Abstract：Objective To analyze the effect of electrocardiogram(ECG) RT fusion on prognosis in first aid. Methods ECGs were recorded in 218 critically ill patients. According to whether or not the ST segment disappears, they were divided into RT fusion group and nonfusion group first. Then they were further divided into tachycardia group, normal heart rate group and bradycardia group according to different heart rates. The QRS wave width, QT interval, QTC interval and mortality were compared among the different groups. Results There was significant difference in QRS wave width, QT interval, QTc interval and mortality between RT fusion group and non-fusion group in the patients with bradycardia and normal heart rate（P<0.05）. There was no significant difference in QRS wave width, QT interval and QTc interval(P>0.05) between RT fusion group and nonfusion group in the patients with tachycardia except mortality. Conclusion The essence of RT fusion phenomenon in emergency center of critically ill patients is serious myocardial ischemia, and the ventricular rate reflects the development trend of severity of myocardial ischemia from fast to slow.
