Epicardial stimulation from a left ventricular site through the coronary sinus successfully induced polymorphic ventricular tachycardia in a Brugada syndrome patient after right ventricular stimulation failed.

Does epicardial left ventricular programmed stimulation induce polymorphic VT in a Brugada syndrome patient when right ventricular stimulation fails?
Epicardial left ventricular programmed stimulation may be useful for risk stratification in Brugada syndrome when standard right ventricular stimulation fails.
CARLSSON, J., et al. : Possible Role of Epicardial Left Ventricular Programmed Stimulation in Brugada Syndrome. A patient with recurrent syncope due to polymorphic ventricular tachcardia was diagnosed with Brugada syndrome. Programmed right ventricular stimulation could not induce arrhythmia. Epicardial stimulation from a left ventricular site through the coronary sinus led to polymorhic VT. The stimulation protocol for risk stratification in Brugada syndrome is discussed.
Carlsson et al. (Thu,) conducted a case report in Brugada syndrome (n=1). Epicardial left ventricular programmed stimulation vs. Programmed right ventricular stimulation was evaluated on Induction of polymorphic ventricular tachycardia. Epicardial stimulation from a left ventricular site through the coronary sinus successfully induced polymorphic ventricular tachycardia in a Brugada syndrome patient after right ventricular stimulation failed.
