Twelve-lead electrocardiogram demonstrating 2 mm ST segment elevation in leads V1 and V2 with a prominent J wave followed by negative T waves. Suggestive of a type 1 Brugada pattern.

T waves (Figure 1). This was consistent with a type 1 Brugada pattern, facilitating the patient's referral to our department.
Electrophysiological study demonstrating the induction and termination of ventricular fibrillation. (A) Twelve -lead electrocardiogram demonstrating the induction of ventricular fibrillation through triple extrastimuli at the right ventricular outflow tract. (B) Twelve-lead electrocardiogram demonstrating sustained ventricular fibrillation. (C) Twelve-lead electrocardiogram demonstrating the termination of ventricular fibrillation through a 360-J transthoracic direct current shock and subsequent return to sinus rhythm.

An electrophysiological study was performed, which resulted in the induction of polymorphic ventricular tachycardia after programmed electrical stimulation of the right ventricular outflow tract (Figure 2).
Twelve-lead electrocardiogram after the discontinuation of lamotrigine. The electrocardiogram demonstrates normal sinus rhythm with near resolution of the J-point elevation and type 1 Brugada pattern.

In addition, further electrocardiograms obtained after the discontinuation of lamotrigine therapy display normal sinus rhythm with near complete resolution of the J-point elevation and the type 1 Brugada pattern (Figure 3).
