[Effect of coronary artery patency after myocardial infarction on ventricular late potentials].

This study evaluated the relation between patency of the infarct related artery and the presence of ventricular late potentials (VLP) on the signal-averaged electrocardiogram (ECG). 44 patients (pts) after myocardial infarction (MI) (35 men, 9 women; mean age 50 years) were studied by coronary angiography. measurement of ejection fraction and signal-averaged ECG.
