本文报道1例罕见的非Q波型急性心肌梗塞并发房室传导系统远端持续性Ⅱ°一型传导阻滞。患者女性,75岁,因严重胸骨后疼痛入院。既往患轻度糖尿病和双分支阻滞(左前分支阻滞和不全性石束支阻滞)。入院后血清酶呈典型AMI曲线变化,临床上因并发房室传导阻滞而安装永久性心肌起搏器治疗。图1示下壁和前侧壁导联新出现ST段压低和T波例置,而无明显病理性Q波和R波振幅降低,此种心电图表现符合下壁和前侧壁急性心内膜下心肌梗塞(非Q波型梗
This article reports a rare case of non-Q wave acute myocardial infarction complicated by atrioventricular conduction system distal persistent Ⅱ ° -type block. Female, 75 years old, admitted to hospital for severe chest pain. Previously suffering from mild diabetes and bifurcation (left anterior branch block and incomplete bundle branch block). Serum enzyme showed a typical change of AMI curve after admission. Clinically, permanent myocardial pacemaker was installed due to concurrent atrioventricular block. Figure 1 shows the inferior wall and anterior wall leads new ST-segment depression and T-wave set, without significant pathological Q-wave and R-wave amplitude reduction, such ECG performance consistent with inferior and anterior wall acute endocardium Lower myocardial infarction (non-Q wave stems
