[Relation of elevated ST segment in the electrocardiogram to echocardiography determined wall kinetics in patients after myocardial infarct].

The connection of ECG findings and disturbances of the kinetics after myocardial infarction was controlled on 104 patients in correlation to the echocardiography. The investigations were performed at discharge from hospital and in the 3rd month after infarction by means of ECG at rest and exercise electrocardiogramme as well as echocardiography. In this case was shown that the elevation of the ST-segment after anterior-wall infarction was above all the expression of an ischaemia and was in most cases accompanied by an akinesia of the anterior wall. Only patients with a precordial ST-elevation over 2 mm at rest with increase to more than 4 mm under exercise or patients with a smaller ST-elevation, but a symptom-limited performance to 50 Watt, connected with ST-elevation, ventricular extrasystoles or pathological diastolic pressure of the pulmonary arteries as withdrawal criterion belonged to the group with dyskinesias and aneurysms, respectively.
