Serial simultaneous M mode echocardiograms, phonocardiograms, and apexcardiograms were recorded and digitised in 20 patients with a first myocardial infarction immediately after and two, three, seven, and 56 days after hospital admission. Left ventricular maximum and minimum dimensions, normalised maximum rate of change of dimension during systole and diastole, and three previously defined indices of the coordination of left ventricular wall motion were measured. Incoordinate left ventricular wall motion was detected in all patients but was more pronounced in those with an anterior infarction (15) than in those with an inferior infarction (5).

Abnormalities of the "A" wave and systolic waves of the apexcardiogram correlated well with akinesia or dyskinesia proven by cinefluoroscopic and cineangiographic studies. Third and fourth heart sounds and apical systolic murmurs also correlated well with evidence of ventricular dysfunction.

Thus, paradoxical bulging (dyskinesis) of the systolic wave or increased "a" wave amplitude with gradual recovery over several weeks was found in all 60 patients with documented ami and in 18 of 20 patients with pia. Electrocardiogram changes were noted, however, in only eight of the pia patients.
