摘　　要：本文报道33例41支血管经皮腔内冠状动脉成形术(PTCA)术中同步监测冠状动脉内心电图(IC-ECG)和体表心电图(S-ECG)的变化.结果提示IC-ECG在球囊充盈时ST段变化发生率高于S-ECG,其抬高幅度亦大于后者且先于后者出现.IC-ECG能灵敏反映PTCA术中心肌缺血的情况,且操作简便.有助于指导PTCA的顺利进行.The changes of intracoronary electrocardiogram (IC-ECG) and surface electro-cardiogram (S-ECG) were recorded simultaneously during percutaneous transluminal coronary angioplasty(PTCA) in 33 cases of coronary heart diseases with 41 vessel lesions. The results sug-gested that ST-segment change rate on IC-ECG(90. 2%) was higher than that on S-ECG(56%). ST-segment elevation on IC-ECG was earlier and more significant than that on S-ECG. The IC-ECG appeared to be more sensitive than S-ECG for detecting myocardial ischemia. The technique for recording IC-ECG is simple and it can help to perfome the PTCA successfully.
