Tpeak-Tend and Tpeak-Tend dispersion as risk factors for ventricular tachycardia/ventricular fibrillation in patients with the Brugada syndrome.

Objectives: Our objective in this study was to evaluate Tpeak-Tend interval (Tp-e) and other electrocardiographic parameters as risk factors for recurrence of life-threatening cardiac events in patients with the Brugada syndrome (BS).

Background: The Tp-e interval in the electrocardiogram (ECG) has been reported to predict life-threatening arrhythmias in the long QT syndrome.

Methods: Twenty-nine patients with the ECG pattern of BS and 29 healthy age- and gender-matched controls were studied.

[Brugada's syndrome: experience in Cuba in 2001].

The Brugada syndrome is the most frequent electrical cause of sudden death in patients with structurally normal heart. It is characterized by ST segment elevation in V1-V3 leads, pseudo right bundle branch block and proneness for episodes of life-threatening ventricular cardiac arrhythmias. The aim of this study was to characterize patients with Brugada syndrome identified in Cuba between 1995 and 2001.
