Impact of ECG changes on the in - hospital mortality after non-cardiac surgeries

In order to assess the preoperative ECG abnormalities on the short-term mortality after operation, a consecutive two sere is of 52 patients, who were undergoing elective surgery were designed in the setting of Shaheed Mobasher Kashani Hospital, Hamedan University of Medical Sceinces. Preoperative characteristic ECG changes in 52 patients were analysed by using Chi-square test in comparison with a group of normal preoperative ECG data. Main results showed that post operative mortality was occurred in 34 patients (%65.4) but only 7 patients (13.34%) with normal ECG were died. Comparing the risk of death between two group showed that in those with abnormal ECG, confidence interval was (%52.38-%78.38J but (%5-%22.46 (P<0.05) in the group with normal ECG Our results suggest that ECG changes before surgery, apart of other effective indexes, appear to have al especially high risk of in-hospital mortality after non-cardiac surgery.
