Methods: Eight hundred normal cases were chosen randomly for study. Ultrasound was carried out in vertical section at xiphoid process, cross section at middle abdomen, and coronary section at the waist to detect the presence of AHV. The function site, number of AHV, caliber, flow velocity and the angle between AHV and IVC were investigated.

随机选健康查体者800例行超声检查，取剑突下纵切、右腋前线纵切、横切和中上腹部横切、肋间斜切，观察AHV的汇入部位、走向、数量、内径及其与下腔静脉轴线的夹角及多普勒波形、流速等。

Results Mitral valve dilatation resulted in a decrease in left atrail diameter from (44±6)mm, a decline in transmitral valve pressure gradient from (18.2±6.8)mm?Hg to (7.2±3.8)mm?Hg, and an increase in mitral valve area from (1.04±0.21)cm2 to (1.98±0.55)cm2. 8 cases of severe restenesis developed.

结果 二尖瓣平均跨瓣压差由(18.2±6.8)mm Hg降至(7.2±3.8)mm Hg，瓣口面积由(1.04±0.21)cm2增至(1.98±0.55)cm2，左房内径由(44±8)mm降至(38±6)mm；8例出现明显再狭窄，其中5例再次PBMV术，3例行瓣膜置换术。

Methods: on the application of doppler echocardiography machine of the 20 healthy elderly and 52 cases of different classification of the elderly hypertensive patients atrioventricular cavity diameter, and left ventricular septal wall thickness after a control, statistics analysis.
