Abstract:
Objective:To study the significance of QT dispersion(QTd) changes in electrocardiogram(ECG) after coronary artery bypass graft. Methods:Forty eight patients scheduled for elective coronary artery bypass graft were studied. The changes of QTd were monitored by 12 lead electrocardiogram system before surgery (as baseline values), at the end of surgery, and 1 4 d and 7 d after surgery.Results:The baseline values for QTd was (56.32?2.25) ms.QTd were significantly longer as compared to the baseline values ( P
