本文应用M-型超声心动图与心电图、心音图同步记录,对56例高原心脏病患者估测了心脏结构和功能的变化,并以50例高原健康人作对照。结果显示患者以右室肥大为主,同时可有左室肥厚。当心功失代偿时心指数正常或减低。左室收缩功能改变不显而左室舒张早期充盈障碍。 In this paper, M-type echocardiography and ECG, phonocardiogram simultaneously recorded in 56 cases of heart disease patients with heart disease assessment of cardiac structure and function changes, and 50 cases of healthy controls for the plateau. The results showed that patients with right ventricular hypertrophy mainly at the same time may have left ventricular hypertrophy. When heart failure decompensated heart index normal or reduced. Left ventricular systolic function was not significantly changed left ventricular diastolic filling syndrome.
