The left ventricular diameter at end-diastole and the thickness of interventricular septum and posterior wall were measured with echocardiography. Left ventricular mass index (LVMI) was calculated.
以超声心动图检测左室舒张末期内径，舒张末期室间隔和左室后壁厚度等，计算左室重量指数(LVMI)。

The heart beating model is described as cusp catastrophe with end node of systole and diastole.
心脏运动的势函数模型是以收缩末和舒张末为节点的尖点突变的形式来表示的。

Arterial compliance was calculated as the integrated area starting at the well-defined nadir of the incisura of the dicrotic notch to the end of diastole of the radial artery pulse wave.
