ABSTRACT

Torsade de pointes is a clinically important ventricular tachyarrhythmia that typically appears in the presence of a long QT interval and which, without prompt identification and treatment, can lead to sudden cardiac death. The prolongation of QT and corrected QT intervals significantly increases the chance of this arrhythmia to appear in congenital or acquired long QT syndromes. In almost all patients, these intervals are markedly long in the period prior to the arrhythmic event. We describe a case of a female patient with a pacemaker who presented this arrhythmia and suffered several syncopal events.
