Неинвазивная оценка сократительной способности миокарда эхокардиографическим методом у детей

Аннотация

The purpos e of the study. Left ventricular end-systolic measurement (ChQSOO') and myocardial contractility index (MTI) and the relationship between cardiac contraction velocity (TsQT) and MTI development of a simple non-invasive method for characterizing myocardial contractility. Materials and styles . 33 children (21 boys, 12 girls) participated in the study. All patients underwent echocardiographic examination of the heart chambers, and systolic, diastolic and mean arterial pressure were studied. Results . The following linear relationship was found: MTI=20.1 (ChQSOO') +1.46 (r=+0.51; p<0.01); TsQT= -0.0075(MTI)+1.71(r= -0.48; p<0.01). Also, in echocardiography, the left ventricular wall and chambers volume standards were given. More than a century later, the Frank-Starling curvature relation is still in use.
