INTRODUCTION Testing for the presence of microvolt T wave alternans (TWA) is useful for arrhythmic risk stratification. Whether antiarrhythmic pharmacotherapy affects the presence of TWA is unknown. We tested whether patients with known ventricular tachyarrhythmias who were receiving amiodarone were less likely to manifest TWA as compared with those not receiving amiodarone. METHODS AND RESULTS Forty-four patients with a history of ventricular tachyarrhythmias and an implantable cardioverter… CONTINUE READING
