动态心动图在无症状性心肌缺血诊治中的临床价值

Clinical value of dynamic dectrocardiogram in detecting silent myocardial ischemia

目的探讨动态心动图对无症状性心肌缺血诊治的临床价值。方法对138例冠心病(心绞痛型)确诊患者行24h动态心动图监测。结果 24h动态心电图观察到138例患者因心肌缺血所致ST段下移516次,其中无症状心肌缺血发作439次(占85.08%)。结论冠心病患者无症状性心肌缺血发生率较高,24小时动态心电图检查对诊断无症状性心肌缺血的敏感性,准确性较高,对于该类型冠心病的防治具有重要意义。

Objective To study the clinical value of dynamic dectrocardiogram in detecting silent my- ocardial ischemia（SMI） for patients with coronary heart disease. Methods One hundred and thirty eight patients with coronary heart disease were detected by 12 lead dynamic electrocardiogram for 24 hours. Re- suits There were 439 SMI episodes （85.08%） in total 516 episodes ST segment depression with myo- cardial ischemia. Conclusion The incidence for SMI in coronary heart disease patients was very high. And the dynamic dectrocardiogram in detecting SMI has many advantages, such as high sensitivity and high accuracy. So it is significant for the prevention of SMI.
