[Evaluation of left ventricular function in ischemic heart disease by systolic phase structure and echocardiographic...

The article describes poly- and echocardiographic examination of the ejection fraction, the mean contraction rate of the perimetric fiber of the left ventricle, the total tension period, the period of left ventricular ejection, and the tension period to ejection period ratio. The results obtained in a group of 17 healthy individuals were compared with the findings in patients with angina pectoris who were divided into 2 groups, one without any serious changes in the coronarogram (19) and the other with pathological changes in the coronary arteries (18). In patients with an abnormal coronarogram, the ejection fraction, the rate of contraction of the perimetric fiber, and the ejection period were considerably reduced. These values showed no significant changes in patients with a normal coronarogram. The ECG data correlated well with the systolic phase structure.
