用最简便的心音图对心脏功能判定的研究,国内外文献尚未见报道。心音图可以准确测定心脏瓣膜开闭时间,掌握心脏疾病的病情程度,[1,17]及时了解克山病心脏功能的变化。我们用心音图对潜在型及慢型克山病人的左,右心室收缩时间间期进行了测定,探讨临床应用的价值和意义。以期达到 With the most simple heart sound chart on the determination of cardiac function research, domestic and foreign literature has not been reported. Heart sound chart can accurately measure the heart valve opening and closing time, grasp the severity of heart disease, [1,17] Keshan disease in time to understand the changes in cardiac function. We use the phonocardiogram of latent and chronic Keshan patients with left and right ventricular contraction time interval was measured to explore the value and significance of clinical application. In order to achieve
