Atrial fibrillation bradycardia

Atrial fibrillation may have hemodynamic consequences. It can decrease cardiac output due to ineffectual atrial systole and increase pulmonary venous pressure resulting in heart failure. Deleterious hemodynamic effects also include nonphysiologic tachycardia, increased valvular regurgitation, and irregularity in ventricular systole. bradycardia — A distinctly slow heartbeat, which may be a normal idiosyncrasy or with causes ranging from regular strenuous exercise to abnormally slow heart stimulus to the side effects of medication Atrial fibrillation electrical cardioversion to restore normal sinus rhythm, including what to expect For patients in persistent atrial fibrillation, electrical cardioversion may be done early in the process to.. The annual risk of stroke may be even higher in patients with AF who have 1 or more of the following risk factors: older than 65 years, female, diabetes mellitus, hypertension, heart failure, coronary artery disease, previous stroke, or transient ischemic attack. Individual stroke risk stratification can now be calculated for patients on the basis of the presence or absence of such risk factors (ie, CHADS2 and CHADS2 VA2S2C risk scores).27 Several strategies including antithrombotic therapy with vitamin K antagonists (VKA), direct oral anticoagulation (DOAC), and antiplatelet therapy with aspirin, dipyridamole, and clopidogrel. DOAC drugs include Factor Xa inhibitors (eg, apixaban, rivaroxaban, edoxban) and direct thrombin inhibitors (eg, dabigatran). Atrial flutter is related to atrial fibrillation and is usually treated in the same way. This booklet is for people who have been diagnosed with atrial fibrillation or flutter. It has been written to help you to..

Rates of successful immediate cardioversion by pharmacologic means have ranged from 40% to 90%, with success more likely to come for patients with AF of shorter duration.45 Unlike electrical cardioversion, pharmacologic cardioversion does not require sedation. Contemporary use of pharmacologic cardioversion in the US occurs in nonelective scenarios in the emergency department or intensive care unit, and also in stable outpatients treated with a unique type of rhythm control strategy referred to as a pill-in-the-pocket approach. Elective pharmacologic cardioversion is uncommon in the U.S given the superiority of a planned electrical cardioversion under sedation with appropriate airway management personnel on hand.Internal cardioversion is performed with the patient under conscious sedation or general anaesthesia. Due to the potential risk of bleeding, warfarin therapy is usually withheld in view of the procedure and resumed afterward. Temporary anticoagulation before and after the procedure can be accomplished with heparin. Internal cardioversion is indicated: Atrial pacing has been shown to delay the onset of atrial fibrillation (AF) when compared with ventricular The role for pacing in the control of AF in patients without bradycardia is uncertain

Guideline statements only address goals in patients with preserved cardiac function. The optimal rate in patients with heart failure has not been fully defined. For example, some studies show that in patients with heart failure, slow ventricular rates are associated with higher mortality and higher ventricular rates may be needed to improve exercise tolerance.17,18 However, patients with heart failure can easily become decompensated when ventricular rates are uncontrolled. Hence, most clinicians use a patient-specific window of optimal rate control that avoids the consequences of both extreme bradycardia and tachycardia.19 Ventricular slowing is accomplished with medications affecting the AV node (Table 1). The most commonly used drug classes are beta blockers and calcium channel blockers. Most patients with persistent atrial fibrillation receive daily suppressive therapy. However, a pill-in-the-pocket, rate-control strategy has been proposed in patients with a low burden of self-terminating AF, though no studies have investigated this strategy.19

Pacemaker implantation without AV nodal ablation should be considered if the problem is simply excessive bradycardia that prohibits the effectiveness of rate-controlling medication, and the rapid ventricular rates are well controlled by medication. For patients with abnormal LV systolic function, a biventricular pacemaker (ie, cardiac resynchronization therapy) should be considered in conjunction with AV nodal ablation based on the results of the BLOCK HF trial.21 For example, if a patient has atrial fibrillation with a heart rate of 150 b/m, it's unlikely that Some patients with bradycardia will maintain a normal blood pressure, due to an endogenous sympathetic..

The intravenous agents approved in the US for immediate pharmacologic cardioversion of AF are procainamide, amiodarone, and ibutilide(Table 2). Amiodarone is the most commonly used drug in emergency department and intensive care unit settings. Pharmacologic conversion of AF can be achieved with oral drugs. The pill-in-the-pocket approach is sometimes used with class Ic drugs like flecainide or propafenone and may be useful for select outpatients in order to quickly abort AF episodes shortly after onset. This approach has the potential to reduce emergency department visits and hospitalizations, but must be carefully initiated and supervised. It is recommended that the first such application of this strategy is done in a monitored environment, such as an emergency department, in order to establish patient-specific safety. Atrial fibrillation patient preferences for oral anticoagulation and stroke knowledge: Results of a Utilizing NOACs in non-valvular atrial fibrillation patients undergoing PCI. Byrne R, Hohnloser S.. Oral anticoagulation should be continued after cardioversion until sinus rhythm has been maintained for at least 4 weeks to allow the atrial transport mechanism to recover. If the cardioversion was performed using the TEE-guided approach with intravenous heparin as the method of anticoagulation, it is advisable to continue intravenous heparin until therapeutic oral anticoagulation is achieved. The decision to initiate and continue anticoagulation for AF shorter than a duration of 48 hours should be based on the presence of other risk factors for thromboembolism. Subgroup analyses from RELY, ROCKET AF, and ARISTOTLE support the use of DOACs at cardioversion in addition to one nonproprietary study.32

Atrial fibrillation rotors represent an emerging concept as a sustaining mechanism for AF involving spiral waves detected by spectral analysis of dominant frequencies recorded by intracardiac mapping catheters. Such spiral waves can be conceptualized as wavelets of consistent electrical activation around a central localized source that could be either structural (ie, scar-related) or purely functional (ie, conduction heterogeneity involving certain cellular sodium and potassium channels). The focal impulse and rotor modulation computational mapping system is used to identify AF rotors.10 Kim A.M., Goldschlager N. (2008) Pseudoventricular fibrillation. Trombert V., Barro J.

Atrial fibrillation may be acutely associated with physiologic stressors such as surgical procedures, pulmonary embolism, chronic lung diseases, hyperthyroidism, and alcohol ingestion. Disease states commonly associated with AF include hypertension, valvular heart disease, CHF, coronary artery disease, Wolff-Parkinson-White syndrome, pericarditis, obstructive sleep apnea, and cardiomyopathy. Considerable research has been devoted to the mechanisms and pathogenesis of AF. Genetic studies have identified specific associations, particularly in the cases of familial AF 4 Achieving a complete understanding of AF is limited by the complexity of this disorder and the heterogeneous patient population it affects. atrial fibrillation.pdf. atrial fibrillation-slides.ppt

Cardioversion in atrial fibrillation describe

  1. ation or an irregular ventricular rhythm seen on the electrocardiogram (ECG) is not always AF. It is necessary to consider and exclude other types of irregular rhythm disturbances, including atrial or ventricular ectopy, atrial tachycardia, or atrial flutter (Figure 1) with variable AV conduction, multifocal atrial tachycardia (Figure 2), and wandering atrial pacemaker. Conversely, a regular pulse or rhythm does not exclude AF. For example, AF can manifest with a regular ventricular response in the presence of AV block or with a ventricular paced rhythm.
  2. Several features of pacemaker systems may be useful for patients with AF. A pacemaker that has the capability to change automatically into a nontracking pacing mode at the onset of an episode of AF (known as mode switching) is essential to avoid the rapid heart rate that might otherwise occur when the pacemaker responds to rapid atrial activity by pacing the heart inappropriately fast in the ventricles. Implantable atrial defibrillators have been developed, either as a stand-alone device or in combination with a ventricular defibrillator. However, the atrial defibrillator has not been widely accepted by patients or physicians. In general, patients have difficulty tolerating even the low-energy internal cardioversion shocks or frequent antitachycardia pacing sequences without the deep sedation provided during conventional external cardioversion.

Pretreatment with antiarrhythmic drugsPretreatment or repeat treatment with antiarrhythmic drugs such as ibutilide, amiodarone, sotalol, propafenone or flecainide increases the likelihood of restoration of sinus rhythm and helps prevent recurrent atrial fibrillation. (2) Enhanced efficacy may involve decreasing the energy required to achieve cardioversion, prolonging atrial refractory periods, and suppressing atrial ectopy that may cause early recurrence of atrial fibrillation. (55-55) Antiarrhythmic medications may be initiated out of hospital or in hospital immediately prior to direct-current cardioversion. Tachycardia-bradycardia syndrome (characterised by bursts of atrial tachycardia interspersed with periods of bradycardia; paroxysmal atrial flutter or fibrillation may also occur).[2] Practice guidelines include recommendations regarding the form of antithrombotic therapy for patients with AF.1 The AHA/ACC/HRS guidelines recommend the CHA2DS2-VASc score to identify patients with AF at low, moderate, or high risk for thromboembolism. A score of 0 is considered low risk and does not require not antithrombotic therapy. A score of 2 or greater is considered high risk and antithrombotic therapy with VKAs or NOACs should be considered. A score of 1 is considered moderate risk for which antithrombotic therapy or aspirin may be considered. The goal of warfarin therapy for preventing stroke and thromboembolism from AF generally is an international normalized ratio between 2.0 and 3.0. The DOAC classes of medications do not require monitoring. Safety and efficacy have been evaluated in administrative datasets in addition to clinical trials leading to U.S. Food and Drug Administration (FDA) approval. Each DOAC drug has unique properties with respect to half-life, renal clearance, and availability of pharmacologic reversal agents.

Tachycardia-bradycardia syndrome in a patient with atrial fibrillation

According to the 2014 American Heart Association (AHA)/American College of Cardiology (ACC)/Heart Rhythm Society (HRS) clinical practice guidelines, AF can be classified based on the duration of episodes. Paroxysmal AF refers to AF that begins suddenly and ends spontaneously within 7 days of onset.1 Persistent AF refers AF that occurs for longer than 7 days and ends spontaneously or with treatment. Long-standing persistent AF refers to patients who have uninterrupted AF for more than a year. Permanent AF refers to AF that persists despite treatment to restore normal sinus rhythm or that is not treated.Atrial fibrillation is the most common sustained cardiac tachyarrhythmia encountered by clinicians worldwide. An estimated 2.7 to 6.1 million people in the United States have Atrial fibrillation with projections to reach nearly 12.1 million in 2030.1,2

Experienced centers, such as Cleveland Clinic, have reported freedom from AF rates of 75% to 80% at 1 year for patients not taking antiarrhythmic drugs with paroxysmal AF following a single catheter ablation procedure and 85% to 90% following a second ablation procedure.55 Approximately 20% to 30% of patients require a second ablation for AF due to recovery in the PVs, the presence of non-PV triggers, or advanced atrial substrate/myopathy. Outcomes for patients with persistent and long-standing persistent AF are lower than for patients with paroxysmal disease with reported 1-year efficacy rates between 50% and 70% following a single procedure and 70% and 80% following a second procedure.

Warfarin is superior to aspirin and also the combination of aspirin and clopidogrel in stroke prevention.29 Aspirin and clopidogrel is superior to aspirin alone in stroke protection among patients that are warfarin ineligible, but is associated with greater bleeding risk.30

Cardioversion should be performed with the patient in a fasting state under adequate general anaesthesia. The anaesthetic agent must 1) provide analgesia and sedation, and 2) cause the least cardiovascular compromise while allowing for rapid recovery. (10-12) Oxygen saturation and electrolytes should be normal and anticoagulation status monitored. Drug levels, such as digoxin and antiarrhythmic agents, should be within the therapeutic range. Digoxin shouldn't be withheld unless there is a suggestion of digitalis excess or toxicity. (11) A baseline 12-lead electrocardiogram should be recorded and venous cannulation should be secured. A pacing catheter may be placed prophylactically in the right ventricle if sick sinus syndrome is suspected. For backup, external pacing pads may be used for both cardioversion and for prophylaxis should asystole or bradycardia ensue. Overnight hospitalisation is seldom required. (10)The prevalence of AF, already at epidemic proportions, is expected to continue to increase as the population ages and more patients with heart disease live longer. This is especially true for patient with heart failure. The rapid growth of catheter-based and surgical ablation procedures is promising and has already relieved many patients of the burden of AF and the side effects and toxicities of antiarrhythmic medications. However, these approaches are invasive and inherently destructive, and associated with a small but important risk of serious complications. Technological innovation in mapping systems, catheter design (including the use of contract force sensors), and novel energy sources are further expected to improve the safety and perhaps effectiveness of these procedures.

During atrial fibrillation the atria show chaotic depolarisation with multiple foci. Mechanically the atria stop contracting after several days to weeks of atrial fibrillation, the result of the ultra-rapid depolarisations that occur in the atria, typically around 400 bpm, but up to 600 bpm Direct current cardioversion is one of the most effective means of converting atrial fibrillation into sinus rhythm. Medical cardioversion is one alternative. However, direct current cardioversion has the highest overall success rate. (1,2) In all, patients who require cardioversion will often undergo direct current cardioversion rather than pharmacologic conversion because of its: atrial fibrillation rhythm, with a ventricular rate of 100-130. beats/min, was observed followed by a Tachycardia-bradycardia syndrome. Atrial fibrillation is classified into 4 types according to its Additional research informing the genetic aspects of AF is also expected to impact the management of AF. Genetic approaches to AF have identified common genetic variants (like chromosome 4q25 locus) that modulate susceptibility to AF and response to contemporary therapy.59 If perfected, AF therapy for AF may be personalized to improve treatment outcomes. Further research into the underlying molecular and genetic causes of AF may lead to novel methods of disease prevention.

For patients who have been in AF for more than 48 hours and are not adequately anticoagulated, electrical or pharmacologic cardioversion should be delayed until appropriate measures are taken to reduce the thromboembolic risk. There are two approaches to reduce thromboembolic risk in these patients. The conventional approach is to administer oral anticoagulation for at least 3 weeks before electrical or pharmacologic cardioversion. The second approach is transesophageal echocardiography (TEE)-guided electrical cardioversion method when cardioversion cannot be postponed or an expedited approach is preferred. In such cases, once a therapeutic level of anticoagulation has been achieved with an oral agent, intravenous heparin, or subcutaneous enoxaparin, a TEE may be performed to exclude the presence of an intracardiac thrombus. If no thrombus is seen, cardioversion may be performed. TEE can detect the presence of a thrombus in the left atrium, particularly in the left atrial appendage, which is poorly visualized on transthoracic echocardiography. The TEE-guided approach has been validated in several small multicenter trials as well as in a large, randomized, multicenter trial known as the Assessment of Cardioversion Using Transesophageal Echocardiography (ACUTE) trial.31

There are 3 goals in the management of AF: control of the ventricular rate, minimization of thromboembolism risk (particularly stroke), and restoration and maintenance of sinus rhythm. The first 2 goals are essential for most patients, but the third goal may not be necessary in all patients. The AHA/ACC/HRS guidelines provide a more detailed review of the management of patients with AF treated purely with a rate-controlling approach and those patients treated to restore and maintain normal sinus rhythm (ie, a rhythm controlling strategy).1Patients who have implanted permanent pacemakers or cardioverter-defibrillators can undergo external cardioversion with minimal risk to their devices and themselves, provided appropriate precautions are taken. Devices are typically implanted anteriorly, so the electrode paddle should be at least 8 cm from the pacemaker battery; an anteroposterior paddle position is recommended. (2,53,54) Elective cardioversion should be begun with low energies in order to avoid damage to the pacemaker circuitry and the electrode-myocardial interface. After cardioversion, the pacemaker should be interrogated and evaluated to ensure normal pacemaker function. (2)

Suggested Reading. New mathematical model to study the behavior of the human heart. Flickering of cardiac state could provide early warning for onset of atrial fibrillation Dofetilide, a class III antiarrhythmic, has good efficacy rates and is one of the best tolerated antiarrhythmic drugs in terms of its side effects profile. Importantly, dofetilide has also been shown to be safe for patients with cardiomyopathy, CHF, and ischemic heart disease. Therefore, dofetilide may be considered as an alternative treatment option to amiodarone. Like sotalol, dofetilide drug causes QT prolongation that may result in proarrhythmia and rarely death if excessive and is restricted to patients without advanced renal disease. Its use has been restricted by the FDA to certified prescribers and requires monitored initiation in a hospital setting followed by structured outpatient follow-up. Unlike sotalol, however, dofetilide does not cause excessive bradycardia and thus can be administered to patients without concern for exacerbating preexisting bradycardia. Dofetilide has many potentially lethal drug-to-drug interactions, including with many commonly prescribed antibiotics and antihypertensive drugs. Despite these limitations, many patients experience improved AF control with dofeilide with fewer daily side effects compared with other antiarrhythmic drugs. Sinus bradycardia is common in normal individuals during sleep and in those with high vagal tone, such as athletes and young healthy adults. The electrocardiogram shows a P wave before every QRS..

Atrial flutter is another type of commonly seen supraventricular tachyarrhythmia that is usually caused by a single macroreentrant rhythm within the atria. The risk factors for atrial flutter are similar to those of Afib. In atrial flutter, the atrial rate is slower than in Afib and the ventricular rhythm is usually regular. Treatment is similar to that of Afib, consisting of anticoagulation and strategies to control heart rate and rhythm. Atrial flutter frequently degenerates into atrial fibrillation.Pacemakers are also implanted in conjunction with catheter ablation of the AV node. This type of ablation is the ultimate method of ventricular rate control and is often reserved for patients with permanent or paroxysmal AF refractory to medical or ablative therapy. The potential benefits of this type of approach extend beyond simply controlling ventricular response, because there is evidence that regularization of the ventricular rhythm also confers hemodynamic or symptomatic benefits, particularly in the heart failure population in conjunction with the use of a biventricular pacemaker. This approach has been shown to be effective and leads to improved quality of life for patients. However, this approach does not address the fibrillating atria, and such patients still require systemic anticoagulation for thromboembolism and stroke prevention. Managing atrial fibrillation The main goals of AF management are to prevent thromboembolic complications and decrease symptoms by controlling the heart rate or restoring normal sinus rhythm Consider using the HAS-BLED Score instead of, or in conjunction with, other bleeding risk scores such as HEMORR2HAGES and ATRIA to determine risk of major bleeding in a patient with atrial fibrillation Persistent atrial fibrillation: Episodes of AF not terminating spontaneously or lasting longer than 7 days or requires cardioversion.

Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by the rapid and irregular beating of the atrial chambers of the heart. It often begins as short periods of abnormal beating, which become longer or continuous over time Published 1-year efficacy rates of AF ablation range from 66% to 86 % in randomized control trials comparing ablation to antiarrhythmic drugs or rate control agents.51 Refinement in techniques have resulted in a lower incidence of complications, notably PV stenosis, which was common in the early era of catheter ablation. Experienced centers have reported high rates of successful AF ablation resulting in discontinuation of antiarrhythmic drug therapy.52,53 The ideal candidate is a patient with paroxysmal AF in the absence of structural heart disease.

Cardiac Arrhythmias - Atrial & Ventricular Fibrillation - Tachycardia & Bradycardia Guidance, advice and information services for health, public health and social care professionals Atrial fibrillation carries a considerable risk for thromboembolism and stroke. The Framingham study has shown that during a follow up period of 30 years, patients with nonvalvular AF had a more than fivefold risk of stroke and the risk of stroke attributed to stroke increased with age.12 Ischemic stroke can be the first manifestation of occult AF, which is also referred to as subclinical AF. Ischemic strokes related to AF tend to be associated with greater morbidity and mortality than from other causes of stroke.23 As the CRYSTAL AF and EMBRACE trials have demonstrated, AF is frequently detected in patients during post stroke cardiac rhythm monitoring in patients with cryptogenic stroke.24, 25 Some data suggests that such asymptomatic AF can carry a worse prognosis ostensibly related to the stroke risk incurred without the presence of symptoms to provide a warning.26

A 12-lead ECG is best to establish the diagnosis of AF. Electrocardiographic findings in AF include the absence of P waves and the presence of low-amplitude, high-frequency atrial fibrillary waves (F waves). The atrial rate varies in the range of 300 to 700 beats per minute. In the absence of drug therapy, a patient with normal AV conduction has an irregularly irregular ventricular rhythm and often has a ventricular rate in the range of 120 to 180 beats per minute.13 The baseline on the ECG strip often is undulating and occasionally has coarse irregular activity (Figure 3). This activity may resemble atrial flutter, but it is not as uniform wave to wave as atrial flutter. Tag: atrial fibrillation. Wearable necklace-ECG can detect abnormal heart rhythm.

Abstract Background Patients with recent-onset atrial fibrillation commonly undergo immediate restoration of sinus rhythm by pharmacologic or electrical cardioversion Study with AMBOSS for: STEP 1 | STEP 2 CK | STEP 2 CS | Shelf Exams Atrial Fibrillation Guidelines. History Establish Severity (including impact on QOL) Identify Atrial Fibrillation Guidelines. Physical Examination Measure blood pressure and heart rate Determine.. If bradycardia develops, reduce the dose to the previous titration step. In patients who develop bradycardia at the recommended initial dosage Discontinue Corlanor if atrial fibrillation develops Atrial Fibrillation Atrial Flutter. Interventions. Drug: warfarin Drug: apixaban. Sinus bradycardia † 1

Despite such significant advantages, the spread of this new methodology in clinical practice has been limited by the need of a laboratory of electrophysiology with fluoroscopy and of specific technical competence for lead positioning, either in the coronary sinus or in the left pulmonary artery. Simplification of the procedure is obviously very important for the future of internal cardioversion, particularly because of the recent improvement in success rates of external cardioversion using biphasic shocks, higher energy shocks or pretreatment with drugs before cardioversion. (24,42,43) Atrial fibrillation (AFib) is an abnormal heart rhythm that causes an irregular and rapid heartbeat. Medications to treat AFib include beta-blockers, blood thinners, and heart rhythm drugs

These AF classifications are not mutually exclusive and it is common for patients with one type of AF to exhibit overlapping features of another type. These classifications are relevant clinically with respect to outcomes and prognosis with rhythm-controlling treatment strategies. Atrial fibrillation is commonly associated with other supraventricular arrhythmias, namely atrial flutter and focal atrial tachycardia.Atrial fibrillation (AF) is a common heart rhythm disorder caused by degeneration of the electrical impulses in the upper cardiac chambers (atria) resulting in a change from an organized heart rhythm to a rapid, chaotic rhythm. The resulting arrhythmia is often rapid and irregular with no discernible pattern (known as irregularly irregular). The disrupted rhythm occurs because of the unpredictable conduction of disordered impulses across the electrical bridge, called the atrioventricular (AV) node, to the lower cardiac chambers (ventricles). The arrhythmia also results in ineffectual atrial contractions affecting cardiac output and vulnerability to blood clot (thrombus) formation that can result in stroke events. Used to treat Atrial Fibrillation, Atrial Flutter, Atrial Tach, and Symptomatic VT. Shock performed at peak of R wave. Requires proper lead/pad placement to monitor ECG Atrial fibrillation. In some cases pathological foci of heart cells are created, which themselves begin to generate a pulse. If there are many such foci, the work of the heart becomes uncoordinated and..

Dronedarone is an antiarrhythmic drug designed to function similarly to amiodarone but without the molecular iodine interface associated with some of the previously described amiodarone toxicities. Early enthusiasm for this drug, based on results from the initial studies, was later tempered by safety concerns and limitations. The biggest safety concern with this drug involves use in patients with CHF. It is contraindicated for patients with advanced (New York Heart Association functional class IV failure) and was found to increase cardiovascular death rates when given to patients with permanent AF in the Permanent Atrial Fibrillation Outcome Study Using Dronedarone on Top of Standard Therapy (PALLAS) study.47 This drug also has gastrointestinal side effects that can be partially mitigated by taking the drug with food. It also has some important drug-to-drug interactions, including with the anticoagulant drug dabigatran. That said, it is a reasonable treatment option for patients without structural heart disease or advanced liver disease and does not require hospital-based initiation like dofetilide. It has also been one of the most heavily studied antiarrhythmic drugs on the market.However after cardioversion, potential life-threatening complications, such as arrhythmias and thromboembolism, remain a possibility.

Bradycardia is a condition of the heart, where the heart is beating in a (sometimes irregular) rhythm that is too slow to maintain sufficient supply of oxygenated blood throughout the body These findings suggested that both the ventricular bradycardia and the atrial fibrillation were caused by frequent APBs and that pacing therapy was unnecessary The relationship between atrial fibrillation and coronary artery disease is more complex. Such excitement is rarely good therapy for atrial fibrillation. In treating patients with AF, it's good to give..
