[M-echocardiographic determination of left-ventricular diastolic noncompliance, diastolic wall stress and the rate of relaxation of the circumferential muscle fibers].

New noninvasive contemporary indices for assessment of left ventricular diastolic function are presented. They can be obtained by the simultaneous recording of the M-echocardiographic left ventricular dimensions and the apexcardiogram. These indices are: left ventricular diastolic compliance, left ventricular wall stress and the velocity of the circumferential fibre shortening.
