作者用超声心动图研究房室环运动与左心房、左心室大小变化的关系,并且比较20例健康对照者与左心室肥厚(n=28)或扩大(n=16)的病人的心失超声心动图和二尖瓣血流的多普勒超声频移谱。在左心室收缩期,左心房和左心室共有的结构——房室环——向心失移动,使左心房的容量增加。这一运动与肺静脉回流相适应,因为此时从主动脉根部到左房后壁的左房前后径增大。在舒张早期流经二尖瓣的血流加速时,二失瓣环快速移向左心房。这需要一个由左心室朝向左心
The author used echocardiography to study the relationship between AV motion and left atrium and left ventricular size changes and compared 20 patients with left ventricular hypertrophy (n = 28) or enlarged (n = 16) Echocardiography and Doppler Ultrasound Frequency Shift Spectrum of Mitral Flow. In the left ventricular systole, left atrium and left ventricular common structure - atrioventricular ring - heart loss of movement, so that the capacity of the left atrium increased. This exercise is compatible with pulmonary venous return because the anterior-posterior diameter of the left atrium increases from the root of the aorta to the posterior wall of the left atrium. In the early diastolic flow through the mitral valve of the blood flow, the two lost ring quickly moved to the left atrium. It takes a left heart from the left ventricle
