ST-T Alternans as a Risk Predictor for Fatal Ventricular Arrhythmia —Reply

In Reply We express our gratitude to Zhao and Wang for their interest in our recent case report in which we detailed polymorphic ventricular tachycardia (PMVT) triggered by premature beats from Purkinje fibers. This occurred within the context of giant R-wave syndrome stemming from coronary artery disease (CAD). We wholeheartedly concur with the statement that ST-T −wave alternans (STTA), serving as an indicator of focal abnormalities in myocardial electrical repolarization, are associated with ventricular arrhythmias in CAD.
