【摘要】目的探讨12导联24 h动态心电图对诊断无症状性心肌缺血及心肌缺血定位的准确性。方法选择100例12导联24 h动态心电图检出无症状心肌缺血的患者，并对其缺血定位，同期行冠脉造影检查，以比较动态心电图对诊断无症状心肌缺血及缺血部位定位的准确性。结果冠脉造影检出至少一支主要冠状动脉或其分支的内径狭窄≥50患者85例，12导联24 h动态心电图心肌缺血部位与冠脉造影病变血管供血范围相符率为85%。结论12导联24 h动态心电图是诊断无症状心肌缺血的有效方法，并能准确定位缺血部位。

【Abstract】ObjectiveTo investigate the diagnosis and positioning accuracy of SMI by 12-lead 24 hours Holter.MethodsChoose the patients who are suffered from silent myocardial ischemia what were checked out by 12-lead 24 hours Holter,at the period,do coronary angiography operation on these patients and compare with the Holters results.At last，estimate the diagnosis and positioning accuracy of silent myocardial ischemia by 12-lead 24 hours Holter.Reaults85 paitients had been found that at least one of their main coronary vessels or one of their branch of coronary vessels were narrow more than 50% by coronary angiography ......
