Highlights that idiopathic RVOT arrhythmias, typically considered benign, can rarely lead to sudden death, especially in the presence of short-coupled PVCs or polymorphic NSVT.
Short-coupled PVCs or polymorphic NSVT may signal risk in presumed-benign RVOT arrhythmias; leaves open refined risk stratification.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract (RVOT) and idiopathic RVOT extrasystoles are generally considered benign arrhythmias. We describe the case of a patient with typical RVOT arrhythmias without any symptoms for many years, who died suddenly the day before a planned electrophysiological study. The only disquieting signs in her clinical history were a relatively short coupling interval of premature ventricular contractions in some ECG recordings and an isolated run of polymorphic nonsustained ventricular tachycardia induced by an RVOT extrasystole during previous ECG monitoring.
