[Electro- and echocardiographic changes during an angina attack in an ergometrine pharmacological test].
The authors examined 29 patients with ischemic heart disease and 3 patients with neurocirculatory dystonia. According to the results of echocardiography it was found that dilatation of the left ventricle and decrease in its contractility were more pronounced when the anginous attack was attended by a rise of the ST segment on the ECG than when it was attended by depression of the ST segment. During an ergometry-induced anginose attack with no changes on the ECG the diastolic filling of the left ventricle was disturbed but its contractility did not change, which evidently points to early manifestations of ischemic changes in the myocardium.
