ECG Markers of Positive Drug Challenge With Ajmaline in Patients With Brugada Syndrome

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
A prominent S‐wave in lead II on a nondiagnostic baseline ECG is a powerful predictor for unmasking Brugada syndrome during an ajmaline challenge. This subtle sign enhances patient selection for provocation testing and aids in risk stratification, particularly in familial screening.
