Abstract
U-wave changes on surface inferior electrocardiograms (ECGs) of patien ts with coronary artery disease are poorly characterized in comparison with surface precordial ECGs. The tip of the guidewire used for coron ary angioplasty lies close to the lesion and transmits electrical sign als, thus enabling epicardial U-waves to be clearly recorded.(1) The a im of the present study was to investigate U-wave changes in surface i nferior ECGs in relation to epicardial U-wave changes determined by in tracoronary ECG during angioplasty-induced inferoposterior or anterior wall myocardial ischemia.
