Abstract: Objective To explore the correlation difference between dynamic and routine electrocardiogram when used to diagnose asymptomatic myocardial ischemia.Methods Totally 92 coronary disease patients confirmed clinically from April 2014 to May 2016 were divided equally and randomly into an observation group and a control group.The patients in the control group underwent conventional ECG examination,and the ones in the observation group went through 24 h 12-lead dynamic ECG examination.The positive rates of asymptomatic myocardial ischemia were compared in the two groups,and the onset time and the patient state at that moment were analyzed in the observation group,Results The positive rates in the control group and observation group were 47.83％ and 84.78％ respectively,and there was significant difference between them (P＜0.05).The onset time was restrained within 6:00 and 12:00,when the patient was in the state of manual labor,brain work or excitement.Conclusion 24 h 12-lead dynamic ECG gains advantages in early and timely diagnosis of asymptomatic myocardial ischemia,and thus is worthy promoting clinically.
