Implication
May inform post-MI arrhythmia risk assessment; leaves open prospective validation of MTWA before clinical use.

Population
Patients after myocardial infarction (MI)

Intervention
Noninvasive risk stratification techniques including microvolt T-wave alternans (MTWA), signal-averaged electrocardiography (SAECG), heart rate variability (HRV), and heart rate turbulence (HRT)
O
Outcome
Prediction of lethal ventricular arrhythmias and sudden cardiac death
Among noninvasive risk stratification tools for post-MI patients, microvolt T-wave alternans is currently the most promising for predicting malignant ventricular arrhythmias.
