1987年11月～1989年7月,我院收治急性心肌梗塞合并Ⅲ度房室传导阻滞患者12例,应用经静脉右心室心内膜临时和(或)永久起搏11例获得成功,现将结果和体会总结如下。 1 临床与资料 1.1 本组患者男性11例,女性1例,最大年龄75岁,最小年龄54岁,平均64.4岁,全部患者均为急性心肌梗塞Ⅲ度房室传导阻滞,其中下壁心肌梗塞6例,下壁加正后壁心肌梗塞3例,下壁加右室心肌梗塞1例。前壁心肌梗塞2例。起搏前最慢心率19次/分,最快心率40次/分,平均为29.9次/分,其中1例反复发生室性心动过速,心室纤颤,5例发现室性心律失常,2例发生房性心律失常,3例有
From November 1987 to July 1989, 12 cases of acute myocardial infarction complicated with Ⅲ degree atrioventricular block were treated in our hospital. Eleven cases of temporary and / or permanent pacing through the right ventricular endocardium were successfully obtained. The results and experience are summarized below. 1 Clinical and data 1.1 The group of 11 males and 1 females, the maximum age of 75 years, the youngest age of 54 years, average 64.4 years, all patients were acute grade III atrioventricular block heart block, including inferior wall myocardial infarction 6 cases, 3 cases of posterior wall plus posterior wall myocardial infarction and 1 case of inferior wall plus right ventricular myocardial infarction. Anterior myocardial infarction in 2 cases. The slowest heart rate before pacing was 19 beats / min and the fastest heart rate was 40 beats / min, with an average of 29.9 beats / min, including 1 recurrent ventricular tachycardia and ventricular fibrillation, 5 ventricular arrhythmias, 2 Atrial arrhythmia occurred in 3 cases
