The singular and plural forms (torsade de pointes and torsades de pointes) have both often been used. The question of whether either one is grammatically "correct" and the other "incorrect" has repeatedly arisen. This is seen among major medical dictionaries, where one enters only the plural form, another enters the plural form as the headword but lists the singular as a variant, and yet another enters the singular form as the headword and gives a usage comment saying that the plural is not preferred. One group of physicians has suggested[21] that it would make the most sense to use the singular form to refer to the arrhythmia entity (where an arrhythmia may involve one or multiple episodes), and that one might best reserve the plural form for describing repeated twisting during a single episode. Regarding the natural language variation, they concluded, in good nature, "Wasn't it the French who coined the term vive la difference?"[21] There is also a range of conditions and medications that cause or influence the development of torsades de pointes.

In acquired long QT syndrome, the prognosis is excellent once the inciting factor has been identified and reliably withheld.Torsades de pointes is French for “twisting of points” and refers to when the heart’s two lower chambers or ventricles, beat faster than the upper chambers, which are known as the atria.The definition also requires that the QT interval be increased markedly (often to ≥600 msec). Cases of polymorphous ventricular tachycardia in which the QT interval is not prolonged are treated as generic ventricular tachycardia. Torsade usually occurs in bursts that are not sustained; thus, the rhythm strip usually shows the patient's baseline QT prolongation.Implantable cardioverter-defibrillators (ICDs) are useful in instances when torsade recurs despite treatment with beta-blockers, pacing, and possibly left thoracic sympathectomy. Beta-blockers should be used along with ICDs because shock can further precipitate torsade by adrenergic stimulation. In the United States, an ICD for refractory cases may often precede sympathectomy.When the heart beats faster than usual, as in a case of torsades de pointes, it is called tachycardia.

  1. Although I think that “torsades des pointes” is the grammatically correct term, I have used “torsades de pointes” throughout because that is the term used in every document I read, and it is the only way that people will find this point is they need it.
  2. Some authorities recommend supplemental potassium to increase the potassium concentration to high normal, which increases the efflux of potassium from myocardial cells, thus causing rapid repolarization.
  3. Torsades de pointes is a specific form of polymorphic ventricular tachycardia in patients with a long QT interval. Current guidelines recommend the ICD for patients resuscitated from cardiac arrest and those with syncope despite beta-blocker treatment
  4. The electrolyte disturbances that have been reported to precipitate torsade include hypokalemia and hypomagnesemia. These disturbances cause a delay in phase III (ie, reprolongation) and form the substrate for emergence of the dysrhythmia. Close observation is required in predisposed patients, such as those with cirrhosis or hypothyroidism.

The original report described regular variation of the morphology of the QRS vector from positive to net negative and back again. This was symbolically termed torsade de pointes, or "twisting of the point" about the isoelectric axis, because it reminded the authors of the torsade de pointes movement in ballet. Most cases exhibit polymorphism, but the axis changes may not have regularity. Torsades de pointes is usually preceded by a short-long-short ECG sequence (Figure More recent studies have also provided guidelines for the estimation of transmural S. Viskin, Torsades de pointes, Current Treatment Options in Cardiovascular Medicine.. We found at least 10 Websites Listing below when search with torsades de pointes treatment on Search Engine The ECG tracing in torsades demonstrates a polymorphic ventricular tachycardia with a characteristic illusion of a twisting of the QRS complex around the isoelectric baseline (peaks, which are at first pointing up, appear to be pointing down for subsequent "beats" when looking at ECG traces of the "heartbeat"). It is hemodynamically unstable and causes a sudden drop in arterial blood pressure, leading to dizziness and fainting. Depending on their cause, most individual episodes of torsades de pointes revert to normal sinus rhythm within a few seconds; however, episodes may also persist and possibly degenerate into ventricular fibrillation, leading to sudden death in the absence of prompt medical intervention. Torsades de pointes is associated with long QT syndrome, a condition whereby prolonged QT intervals are visible on an ECG. Long QT intervals predispose the patient to an R-on-T phenomenon, wherein the R-wave, representing ventricular depolarization, occurs during the relative refractory period at the end of repolarization (represented by the latter half of the T-wave). An R-on-T can initiate torsades. Sometimes, pathologic T-U waves may be seen in the ECG before the initiation of torsades.[16]

In a young patient with torsade, a diagnosis of congenital long QT syndrome should be considered, especially if a family history of sudden cardiac death or sudden infant death syndrome is present. In these patients, episodes of torsade are triggered by adrenergic stimulation such as stress, fear, or physical exertion, [17] but other predisposing factors also should be considered. See Long QT Syndrome.The treatment of torsades de pointes aims to restore a normal rhythm and to prevent the arrhythmia recurring. While torsades may spontaneously revert to a normal sinus rhythm, sustained torsades requires emergency treatment to prevent cardiac arrest.[18] The most effective treatment to terminate torsades is an electrical cardioversion - a procedure in which an electrical current is applied across the heart to temporarily stop and then resynchronise the heart's cells.[18] Treatment to prevent recurrent torsades includes infusion of magnesium sulphate,[19] correction of electrolyte imbalances such as low blood potassium levels (hypokalaemia), and withdrawal of any medications that prolong the QT interval. Treatments used to prevent torsades in specific circumstances include beta blockers or mexiletine in long QT syndrome.[20] Occasionally a pacemaker may be used to accelerate the heart's own sinus rhythm, and those at risk of further torsades may be offered an implantable defibrillator to automatically detect and defibrillate further episodes of the arrhythmia.[20] Torsade is 2-3 times more common in women than in men. Women have longer QT intervals, [15] as well as have more QT prolongation secondary to drug therapy. Congenital long QT syndrome is autosomal in genetic transmission but shows a greater frequency of expression and a greater lengthening of the QT interval in women than in men. Implementation of the Standard Treatment Guidelines and Essential Medicines List is still a major challenge.

Torsade de pointes: A ventricular tachycardia characterized by periodic twisting of the points of the QRS complexes and rates between 200 and 250 beats per minute To address this challenge, the guide is also available on the Internet and will be updated regularly by WHO. These guidelines were written using the following methodology: 1. Writing team Each chapter was allocated to a WHO coordinator and at least one non-WHO lead writer Torsade occurs in patients of a wide age range, from newborns to the very elderly. The highest frequency is in patients aged 35-50 years. Torsade that occurs at an early age usually is due to congenital long QT syndrome. In older persons, it usually is due to acquired long QT syndrome. In a systematic review, investigators found that slightly over half (50.8%) of elderly patients (age ≥80 years) with drug-induced torsade experienced it as the result of "reckless administration" of a QT-interval prolonging agent. [16] The most common occurrences of reckless administration of a QT-interval prolonging were in conjunction with another such agent (51.6%) or despite a known QT-interval prolongation (25.8%). [16]

Pharmacologic interventions should be reserved for patients who are a.. The etiology and management of torsade are, in general, quite different from those of garden-variety VT. In particular, the use of group IA antidysrhythmic drugs, which tend to prolong the QT interval, can have disastrous consequences in torsade. Differentiating between these entities, therefore, is critically important.

Torsades de pointes or torsade de pointes (TdP) (French: [tɔʁsad də pwɑ̃t], translated as twisting of peaks) is a specific type of abnormal heart rhythm that can lead to sudden.. Common causes for torsades de pointes include drug-induced QT prolongation and less often diarrhea, low serum magnesium, and low serum potassium or congenital long QT syndrome. It can be seen in malnourished individuals and chronic alcoholics, due to a deficiency in potassium and/or magnesium. Certain drugs and combinations of drugs resulting in drug interactions are common contributors to torsades de pointes risk. QT-prolonging medications such as clarithromycin, levofloxacin, or haloperidol, when taken concurrently with cytochrome P450 inhibitors, such as fluoxetine, cimetidine, or particular foods including grapefruit, can result in higher-than-normal levels of medications that prolong the QT interval in the bloodstream and therefore increase a person's risk of developing torsades de pointes. In addition, patients with inherited long QT syndrome have a very high risk of episodes of TdP and that risk can be further increased by drugs and electrolyte disorders that further prolong QT.

Treatment for seven to 14 days is recommended, but should be individualized to the patient's clinical response. Cultures from abscesses and other purulent infections are recommended in patients who have received antibiotic therapy, those with severe local infection or signs of systemic illness.. Torsades de Pointes(TdP), is a polymorphic ventricular arrhythmia that can progress to v-fib of sudden death. Characterized by QRS complexes of changing amplitude that appear to twist around the isoelectric line. Can be asymptomatic, or can cause palpitations.. Methadone maintenance treatment (MMT) is commonly used for chronic pain control and for substitution in heroin addicts undergoing rehabilitation. Methadone is known to prolong QT interval and sometimes cause torsade de pointes (TdP) and ventricular fibrillation (VF)

Torsades de pointes is usually not sustained and terminates spontaneously but frequently recurs unless the underlying cause is corrected. Torsades de pointes may degenerate into sustained ventricular tachycardia or ventricular fibrillation. Torsades is a life-threatening arrhythmia and may present as sudden cardiac death in patients with structurally normal hearts.Torsades de pointes is a ventricular tachycardia. In the unstable patient, cardiovert. In the pulseless, defibrillate. (The polymorphic nature of the rhythm may interfere with the defibrillator’s ability to synchronize, so cardioversion may not be possible. In that case, in the unstable patient, deliver an unsynchronized shock.)1 Antiarrhythmic drugs reported to be etiologic include class IA agents (eg, quinidine, procainamide, disopyramide), class IC agents (eg, encainide, flecainide), and class III agents (eg, sotalol, amiodarone).

This guideline strongly recommends opioid agonist treatment with buprenorphine-naloxone as the preferred first-line treatment when possible, because methadone who were experiencing torsades de pointes to buprenorphine corrected the condition.48,49 Magnesium is the drug of choice for suppressing early afterdepolarizations (EADs) and terminating the arrhythmia. Magnesium achieves this by decreasing the influx of calcium, thus lowering the amplitude of EADs. [19] Torsades de pointes or torsade de pointes (TdP) (French: [tɔʁsad də pwɑ̃t], translated as "twisting of peaks") is a specific type of abnormal heart rhythm that can lead to sudden cardiac death. It is a polymorphic ventricular tachycardia that exhibits distinct characteristics on the electrocardiogram (ECG). It was described by French physician François Dessertenne in 1966.[1] Prolongation of the QT interval can increase a person's risk of developing this abnormal heart rhythm.

Torsades de pointes is a distinctive polymorphic ventricular tachycardia in which the QRS amplitude varies and the QRS complexes appear to twist around the baseline. Torsades de pointes is associated with a prolonged QT interval, which may be congenital or acquired.[1, 2]Shah M, Carter C. Long QT syndrome: a therapeutic challenge.

I have seen that repeated 2 or 3 times in the first hour – so that would be more than 100meq through a peripheral IV over an hour. The magneisum doses used in obstetrics are usually considerably higher than we use elsewhere, and it gives me some comfort. I have never started a central line for magnesium, and I had a similar case that was defibrillated more than 30 times before the Torsades was controlled. I just kept pushing mag through the peripheral IV. However, mag dosing isn’t a topic that I have specifically looked into.Close follow-up is needed because of a risk of sudden cardiac death. Offer emotional support; suggest attending a cardiac support group.Repolarization of the cardiomyocytes occurs in phases 1-3, and is caused predominantly by the outward movement of potassium ions. In Torsades de pointes, however, the repolarization is prolonged; this can be due to electrolyte disturbances (hypokalemia, hypomagnesemia, hypocalcemia), bradycardia, certain drugs (disopyramide, sotalol, amiodarone, amitriptyline, chlorpromazine, erythromycin) and/or congenital syndromes.[13]

However, guidelines can never replace clinical expertise when treatment decisions for individual patients are being taken. Guidelines help to focus decisions. Clinical decisions must also take into account patients' personal values and preferences and their individual circumstances This Guideline is intended to provide guidance on the clinical development of new medicinal products for the treatment of pain. It replaces and updates the separate guidelines on neuropathic (CPMP/EWP/252/03) and nociceptive pain (CPMP/EWP/612/00) In terms of distilling information – I find its best to approach it from both directions. Find people that have already summarized the literature, look at their citations, and download those to have a look for yourself. At the same time, do a search of pubmed or google scholar to see if you uncover any important information they missed. Its a little more timely, but at the end of the day you will be a lot more certain that you ended up with the best answer.

The physical findings in torsade depend on the rate and duration of tachycardia and the degree of cerebral hypoperfusion.Other tests should be ordered depending on the etiological factors being considered (see the section Etiology of Torsade). Although Torsades de Pointes (TdP) is a rare ventricular arrhythmia, it can degenerate into ventricular fibrillation TREATMENT: if unstable - Unsynchronized Cardioversion (Defib) 120-200 J biphasic, 360 J monophasic. Based on AHA ACLS 2016 Guidelines These guidelines are current until they are replaced on October 2020. If patient has torsades de pointes rhythm on ECG. Management and treatment for a stable tachycardia with a wide QRS complex and either a regular or irregular rhythm should be done in the hospital setting with expert..
