Ventricular tachyarrhythmia induced by low doses of sotalol: torsade de pointes or polymorphous ventricular tachycardia?

Abstract

A case of QT prolongation and ventricular tachyarrhythmia in a 57-year-old patient treated with small therapeutic doses of sotalol is reported. There was no concomitant treatment prolonging the QT interval. Hypokalemia could be excluded. Before treatment an electrophysiological study was performed, and ventricular tachycardia could not be initiated. Coronary artery disease was excluded. QT prolongation and ventricular tachyarrhythmias induced by small therapeutic doses of sotalol in normokalemia may occur on rare occasions. It may be problematic to differentiate between torsade de pointes and polymorphous ventricular tachycardia when describing such a ventricular tachyarrhythmia.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
