1960年以来,有关室内传导阻滞与房室传导阻滞的关系,多数学者提出了单支、双支以及三支阻滞的新概念。左室有器质性病变时往往伴有左前分支阻滞(以下简称LAH),因此对LAH的心电图表现,应引起足够的重视。现将我们见到的115例复习如下: 资料诊断标准:本组的诊断标准是Ⅱ、Ⅲ、aVF呈rS,Ⅰ、aVL呈qR,S_Ⅲ>S_Ⅱ,电轴左偏-45°以上,一般QRS时间在0.10秒以内。临床及心电图资料:本组心电图诊断为LAH者115例,男性99例,女性16例。年龄分布、
Since 1960, regarding the relationship between conduction block and atrioventricular block, most scholars proposed the new concept of single branch, double branch and three blocks. Left ventricular organic disease is often accompanied by left anterior branch block (hereinafter referred to as LAH), so the performance of LAH ECG should be given enough attention. Now we see the 115 cases reviewed as follows: Data diagnostic criteria: the diagnostic criteria of this group is Ⅱ, Ⅲ, aVF was rS, Ⅰ, aVL was qR, S_Ⅲ> S_ Ⅱ, left axis deviation of -45 ° above the general QRS The time is within 0.10 seconds. Clinical and ECG data: The group of 115 cases of LAH ECG diagnosis, 99 males and 16 females. age distribution,
