Abstract:
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.
