本文分析了25名正常人和21名二尖瓣狭窄病人的舒张期左室后壁斜率。目的为:(1)舒张期左室后壁斜率与计算的二尖瓣口面积的相关性。(2)左室后壁斜率预测二尖瓣狭窄的价值。(3)估价人工瓣机能障碍的价值。使用M型超声心动图记录了21名二尖瓣狭窄病人的左室后壁标准区,其中8人
This article analyzes the diastolic left ventricular posterior wall slope in 25 normal subjects and 21 patients with mitral stenosis. The purpose is: (1) The correlation between the diastolic left ventricular posterior wall slope and the calculated mitral orifice area. (2) The value of left ventricular posterior wall slope predicts mitral stenosis. (3) Valuation of artificial valve dysfunction value. M-mode echocardiography was used to record the posterior wall of 21 patients with mitral stenosis in the standard region, of which 8
