ABSTRACT
The correlation of indices of the phase structure of the left ventricular systole in patients with isolated left ventricular (140 patients) and combined biventricular (60 patients) myocardial infarction showed prolonged tension time resulting from isometric contraction, and a great difference between the actual and proper systolic values in the affection of both ventricles irrespective of the outcome of disease. In low sensitivity of indices of the phase analysis of the left ventricular systole the following indices proved to be specific and informative for recognition of the right ventricle involvement: a period of isometric contraction, duration of the common systole, difference between the actual and proper systolic values, and tension time.
