左前分支支配左室前壁包括室间隔、左室侧壁、左室心尖。左前分支阻滞(LAH)改变了前壁心室激动顺序,使前壁心肌梗塞的心电图形发生变异,造成误诊或漏诊。一、前壁心肌梗塞解剖上是指空间隔与前乳头肌中部之间的心肌梗塞,它位于左前方,当梗塞后左前方向量缺失,使QRS环移
The left anterior branch dictates the anterior wall of the left ventricle including the ventricular septum, the left ventricular wall, and the apex of the left ventricle. Left anterior branch block (LAH) changes the anterior chamber ventricular activation sequence, so that the anterior myocardial infarction ECG variability, resulting in misdiagnosis or missed diagnosis. Anterior myocardial infarction Anatomy refers to the spatial separation and anterior myocardial papillary muscle between the middle of the infarction, which is located in the left front, when the left anterior infarction infarction vector, the QRS shift
