[Late ventricular potentials in patients without ventricular tachycardia 3 years after myocardial infarct].

In 57 patients who in the course of 29-48 months (mean 36 months) after myocardial infarction did not develop sustained ventricular tachycardia, late ventricular potentials were investigated. Positive findings were revealed in 13 (22.8%) patients using a 25-250 Hz filter and in 14 patients resp.
