[Late ventricular potentials in acute and rehabilitative periods of myocardial infarct].
The study was undertaken to examine 121 individuals: 48 apparently healthy subjects, 43 patients with angina pectoris and 42 patients with acute myocardial infarction (MI). Late ventricular potentials (LVP) were recorded in 6.2% of healthy subjects, 25.6% of patients with angina and 40.5% of those with MI in the first 24 hours, 28.5% on day 3, and 45.2% on day 14 of the onset of infarction. They were not recorded in 35.7% of MI patients. On days 3-4 of MI, the presence of LVP depended on the severity of diastolic left ventricular dysfunction; on day 14, LVP occur more frequently with circular than with anterior MI; in days 3 and 14, LVP were recorded much more frequently with Q wave; the total R-wave amplitude in leads V2-V4 is of definite importance for LVP in anterior MI, whereas that in 35 leads is of definite significance in posterior MI.
