摘要
目的 探讨冠状动脉内心电图(IC-ECG)在经皮冠状动脉腔内成形术(PTCA)术中的应用。方法对44例冠心病病人的51支冠状动脉行PTCA时记录IC-ECG和体表ECG,分析心绞痛组、心肌梗塞溶栓再通组、溶栓未通组IC-ECG的缺血性心电图改变情况,并与体表监护导联ECG相比较。结果96.1%的血管行球囊扩张时IC-ECG有缺血性改变;心绞痛组、心肌梗塞溶栓再通组及溶栓未通组的IC-ECG的ST段上移程度有明显差别。结论IC-ECG比体表ECG在反映心肌缺血方面更敏感,PT-CA时IC-ECG的ST段变化能一定程度地反映残余心肌的成活情况。
Objective To determine the usage of intracoronary ECG (IC-ECG) in the procedure ofpercutaneous transluminal angioplasty. Methods 44 patients with 51 vessel IC-ECG during PTCA procedure were recorded. Three group of patients were compared, angina group, AMI with successfulreperfusion and AMI with reperfusion failed. Results 96.1% vessels had significant ischemia on ICECG during balloon inflation. ST segment elevation on IC-ECG had significant difference among threegroups. Conclusion IC-ECG can be more sensitive than surface ECG in reflecting cardiac ischemia. Insome extent, ST segment elevation on IC-ECG during balloon inflation can reflect the amount of viablecardiac muscle.
