May aid post-MI VT separation beyond Holter or LVEF; hypothesis-generating and requires prospective validation before practice change.
Does high-resolution and signal-averaged ECG accurately separate post-myocardial infarction patients with and without ventricular tachycardia compared to standard clinical parameters?
Combinations of signal-averaged ECG parameters provide better separation of post-MI patients with and without ventricular tachycardia compared to Holter monitoring, ejection fraction, or age.
