1980年1月至1988年2月,我院收治冠状动脉硬化性心脏病合并急性心肌梗塞(A M I)120例,通过临床分析,进一进探讨不同部位 A M I 心律失常及其临床意义。临床资料120例 A M I 主要诊断依据为:①临床症状;②心电图变化表现。其中男81例,女39例,大于60岁者65例。左心室前部位 AM I87例,左心室后部位 A M I 30例,急性心内膜下心肌梗塞3例。87例左心室前部位 A M I 中室性心律失常35例占41.3%,其中室性早搏31例,占35.6%,室颤4例(5.7%)。其次为完全性束支传导阻滞10例,占11.4%。39例左心室后部位 AM I 中,心律失常房室传导阻滞8例,占26.6%,其中Ⅱ度房室传导阻滞5例,占16.6%,Ⅲ度房室传导
From January 1980 to February 1988, 120 cases of coronary heart disease complicated with acute myocardial infarction (AMI) were admitted to our hospital. Through clinical analysis, we further explored the clinical significance of AMI arrhythmias in different parts. Clinical data 120 cases of A M I based on the main diagnosis: ① clinical symptoms; ② ECG changes. There were 81 males and 39 females, 65 more than 60 years old. Left anterior ventricular AM I87 cases, left ventricular posterior AMI 30 cases, acute subendocardial myocardial infarction in 3 cases. There were 35 cases of ventricular arrhythmia in 87 cases of left ventricular anterior myocardial infarction, accounting for 41.3%, including 31 cases of premature ventricular contractions (35.6%) and ventricular fibrillation in 4 cases (5.7%). Followed by complete bundle branch block in 10 cases, accounting for 11.4%. Among 39 cases of left ventricular posterior AMI, 8 cases had arrhythmia atrioventricular block, accounting for 26.6%. Among them, 5 cases were grade Ⅱ atrioventricular block (16.6%), Ⅲ degree atrioventricular conduction
