近年来,心室舒张期顺应性的研究有了较大的进展,心脏舒张性能的研究也引起了重视。采用非创伤性检查方法是当前心功能研究的一个重要方面。近来发现非创伤性检查,如心机械图(MCG)和超声心动图(UCG)测定的指标与创伤性方法测定的指标有良好的相关性。本文采用同步心电图(ECG)、心音图 In recent years, great progress has been made in the study of ventricular diastolic compliance, and the study of diastolic performance has drawn great attention. The use of non-invasive examination is an important aspect of current cardiac function research. It has recently been found that there is a good correlation between noninvasive tests such as cardiac mechanical map (MCG) and echocardiography (UCG) and those determined by traumatic methods. This article uses synchronous electrocardiogram (ECG), phonocardiogram
