临床实践与科研中最普遍应用Ｍ -模式 ,即测定ＬＡ的前后维度以确定ＬＡ体积。现作者新研制出双平面法 (ＢｉｐｌａｎｅＭｅｔｈｏｄ)二维 (2 -Ｄ)超声心动图法测定ＬＡ体积大小 ,它是Ｍ -模式超声心动图测定ＬＡ的优化与改进法。统计学处理证明Ｍ -模式与 2 -Ｄ法测定ＬＡ体积
The most commonly used M-mode in clinical practice and research is the determination of LA anteroposterior dimensions to determine LA volume. The authors newly developed a two-dimensional (Biplane Method) two-dimensional (2-D) echocardiography method for the determination of LA volume size, which is M-mode echocardiography LA optimization and improvement. Statistical analysis proves that LA mode is determined by M-mode and 2-D method
