Abstract

Torsade de pointes (TdP) is an ear-pleasing term that describes an eye-catching pattern of polymorphic ventricular tachycardia (PVT) with continually changing morphology of the QRS complexes that seem to twist around an imaginary base- line [1]. The quasi-musical term and the intriguing ECG pattern have caught the attention of electrophysiologists for years and have been, to some extent, a dri- ving force behind the recent focused interest in the role of genetics and ion chan- nelopathy in cardiac arrhythmias. More importantly, this is helping to refocus attention on the role of dispersion of ventricular repolarization in the genesis of malignant ventricular tachyarrhythmias [2].
