Short coupled premature ventricular contraction initiating ventricular fibrillation in a patient with Brugada syndrome.

Abstract

Patients with Brugada syndrome typically have ST segment elevation in ECG leads V1–V3, infrequent ventricular premature contractions with variable coupling intervals, inducible ventricular arrhythmia during electrophysiologic studies, and ventricular fibrillation (VF). In contrast, patients with short-coupled tosades de pointes (TdP) typically have no ST segment elevation on ECG, with frequent and short-coupled (<300 ms) ventricular premature contractions and TdP but no inducible ventricular arrhythmia. We report the case of a 20-year-old female patient who was admitted with electrical storm
