T Wave Alternans For Risk Stratification in Non-ischemic Dilated Cardiomyopathy
All studies used TWA criteria that included alternans voltage ≥ 1.9 μV and alternans ratio ≥ 3. Unless specified, events in follow up columns reflect patients with a positive TWA test. EF = ejection fraction, HR = heart rate, NSVT = nonsustained ventricular tachycardia, TWA = T Wave Alternans, VT = ventricular tachycardia.
