A 17-year-old woman had two admissions within five months for recurrent episodes of ventricular tachycardia in conjunction with a prolonged QT interval. On both occasions these were refractory to intravenous lidocaine and bretylium. During her first admission her dysrhythmia was controlled by repeated doses of intravenous propranolol; however, she ...

Torsade de pointes is a polymorphic ventricular tachycardia showing a peculiar electrocardiographic pattern characterised by a continuous twisting in QRS axis around an imaginary baseline. An abnormally prolonged QT interval is actually associated with torsade de pointes and it is constantly observed in the sinus beats preceding the onset of the ...

Heart & lung : the journal of critical care, 1981
Prolonged QT or QU intervals can be caused by a variety of conditions which include drugs, electrolyte imbalance, and acquired and congenital diseases. This finding is associated with life-threatening ventricular arrhythmias that, at times, have unusual morphologies characteristically named "torsade de pointes." Treatment, when iatrogenic, is obvious ...

Confederation of Australian Critical Care Nurses Journal, 1990
Torsades de Pointes (T.D.P.) is a ventricular dysrhythmia that is a commonly undiagnosed condition seen within Critical Care areas of most Major Metropolitan Hospitals. It is a condition that requires prompt diagnosis and treatment. Experience has shown a lack of understanding of the clinical features and the treatment of this particular life ...

Current Treatment Options in Cardiovascular Medicine, 1999
The treatment of torsades de pointes is very effective but also very specific. Prompt recognition of torsades de pointes is imperative, and the clue to its recognition is increased awareness. The QT interval in the long QT syndrome (LQTS) is not only prolonged but also odd looking.

Archives of Internal Medicine, 1980
• Two patients with syncope due to an atypical ventricular tachycardia are described. In both, undulation of the QRS axis during episodes of tachycardia, a prolonged QT interval, the initiation of the tachycardia by a late ventricular premature depolarization, and the association with high-degree atrioventricular block suggested a diagnosis of "torsade

Torsades de Pointes. Torsades de pointes are typically characterized by an ECG pattern of polymorphous but organized electrical activity of ventricular origin that occurs in the setting of a long QT interval, long‐coupled bigeminy, and has specific precipitating causes and therapeutic responses.

Resume Les torsades de pointes sont des arythmies ventriculaires rares, particulieres par leur aspect (rotation des QRS autour de l'axe electrique), leurs circonstances d'apparition et leur traitement specifique. De durees variables, elles sont souvent repetitives, formant de veritables orages rythmiques. Quoique rapides, elles peuvent eventuellement

Torsades de pointes is a form of paroxysmal ventricular tachycardia which meets the following morphologic criteria: 1. A ventricular rate typically greater than 200/min. 2. QRS morphology which displays alternating polarity in an undulating pattern so that the complexes appear to be twisting about the base line. 3.

Torsades de pointe were described by Dessertenne as a variety of non-sustained polymorphous ventricular tachycardia in subjects presenting bradycardia due to atrio-ventricular block [1]. The name ‘torsades de pointe’ is now universally accepted and is preferred to other synonyms referring to the same aspect of the waves in the ectopic ventricular ...
