心功不全时,因左室舒张期终末压、左房压力上升,能引起心电图的P波与心音图的第四音——心房音振幅变化。有人提出有潜在性或早期的心功不全,其症状、体征或对照的心电图与心音图均不明显,当然运动负荷后其P波和心房音出现改变,借此可早期发现心功不全病人。我们为早期诊断克山病的心功不全,于1973年冬在点区对26例潜在型,为对照5名慢型克山病和29例健康人群,做了运动负荷试验,重点观察P波和心房音的变化。兹将结果报告如下:
Heart failure, due to end-diastolic left ventricular end-diastolic pressure, left atrial pressure, can cause ECG P-wave and phonocardiogram of the fourth sound - atrial tone amplitude changes. Some people put forward potential or early heart failure, the symptoms, signs or control of ECG and phonocardiogram are not obvious, of course, after exercise load P wave and atrial fibrillation appear to change, which can be early detection of patients with heart failure. We early diagnosis of Keshan disease of heart failure, in the winter of 1973 in the point area of 26 cases of latent type, control for 5 chronic Keshan disease and 29 healthy people, made the exercise load test, focusing on the observation of P wave And atrial tone changes. We report the result as follows:
