目的:探讨动态心电图(DCG)对老年无症状心肌缺血(SMI)的意义。方法:分析131例冠心病SMI患者,按年龄分为老年组和中年组。结果:老年组SMI发生率、SMI出现阵次、以及心律失常发生率均高于中年组(P<0.05或P<0.01)。结论:老年冠心病患者SMI和心律失常发生率高。
Objective: To investigate the significance of ambulatory electrocardiogram (DCG) on senile asymptomatic myocardial ischemia (SMI). Methods: One hundred and thirty-one patients with coronary heart disease (SMI) were divided into the elderly group and the middle-aged group by age. Results: The prevalence of SMI, incidence of SMI and the incidence of arrhythmia in the elderly group were higher than those in the middle age group (P <0.05 or P <0.01). Conclusion: The incidence of SMI and arrhythmia in elderly patients with coronary heart disease is high.
