本文旨在验证如下假说:同仅有下壁梗塞心电图表现者相比,具有后(下)壁梗塞心电图表现者的左回旋支病变发生率较高、程度较重.回顾性选择经冠状动脉造影且有当时心电图资料的44例患者.心电图表现有:单纯后壁梗塞(4例)和下后壁梗塞(17例)属组Ⅰ,单纯下壁梗塞(23例)属组Ⅱ.已除外左室前壁梗塞,右室肥大,右束支传导阻滞,V_(1～6)、I或aVL导联上出现Q波者.右胸导联上出现高而宽的R波(RV_(1.2)型)是后壁梗塞的标志,R波(时间)≥0.03sec,R波(幅度)≥
The purpose of this paper is to verify the hypothesis that the incidence of left circumflex coronary artery lesions in patients with posterior (inferior) wall infarction electrocardiogram is higher and more severe than that of those with only inferior wall infarction ECG.A retrospective review of coronary angiography There were 44 patients with electrocardiogram data at that time.The electrocardiogram showed that simple posterior wall infarction (4 cases) and inferior posterior wall infarction (17 cases) belong to group Ⅰ, simple inferior wall infarction (23 cases) belong to group Ⅱ, Ventricular anterior wall infarction, right ventricular hypertrophy, right bundle branch block, V_ (1-6), I or aVL lead Q wave appeared on the right chest lead high and wide R wave (RV_ (1.2 ) Type) is a sign of posterior wall infarction, R wave (time) ≥ 0.03sec, R wave (amplitude) ≥
