无症状性心肌缺血的动态心电图分析

摘要

Objective To analyze the feature of dynamic electrocardiogram(ECG) of silent myocardial ischemia(SMI) patients to provide basis for clinical diagnosis of SMI. Methods Selected 230 cases of coronary heart disease patients as research objects, its 24-hour Holter monitor, analyzed its dynamic ECG features. Results Out of 230 cases of coronary heart disease patients, 216 cases of myocardial ischemia were detected, the detection rate was 93.9%, incidence of SMI was significantly higher than symptomatic myocardial ischemia, the difference was statistically significant(76.4%VS 23.6%, P0.05]. Conclusion For SMI is lack of clinical symptoms, dynamic electrocardiographic monitoring can provide a reliable basis.%目的分析无症状性心肌缺血(SMI)患者的动态心电图特点,为临床诊断SMI提供依据。方法230例冠心病患者为研究对象,对其进行24 h动态心电图监测,分析其动态心电图特点。结果230例冠心病患者共检出心肌缺血216例,检出率为93.9%, SMI发生率明显高于有症状性心肌缺血,差异有统计学意义(76.4%VS 23.6%, P0.05]。结论无症状性心肌缺血患者缺乏临床症状,动态心电图可以为其提供可靠地依据。
