The processes of contraction and relaxation of the myocardium, the compensatory role of the left auricle were studied by echocardiography in patients suffering from essential hypertension with varied intensity of myocardial hypertrophy of the left ventricle. 44 patients with essential hypertension and 10 healthy individuals were examined. The patients suffering from essential hypertension not attended by myocardial hypertrophy of the left ventricle show an increase in inotropism and in the extent of diastolic relaxation as compared to controls. A significant rise of the myocardial weight of the left ventricle entails a reduction in myocardial contractility and in the extent of diastolic relaxation. As hypertrophy of the left ventricle increases, the compensatory role of the left auricle rises, thus ensuring increased diastolic filling and maintenance of the left ventricular contractility.
通过超声心动图研究了原发性高血压患者左心室心肌肥厚程度不同时心肌的收缩和舒张过程以及左心房的代偿作用。对44例原发性高血压患者和10名健康个体进行了检查。与对照组相比，未伴有左心室心肌肥厚的原发性高血压患者的心肌收缩力和舒张松弛程度增加。左心室心肌重量的显著增加导致心肌收缩力和舒张松弛程度降低。随着左心室肥厚的增加，左心房的代偿作用增强，从而确保舒张期充盈增加并维持左心室的收缩力。
