摘　　要：目的 探讨12导联24h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24h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24h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24h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。Objective To investigate the diagnosis and positioning accuracy of SMI by 12 - lead 24 hours Holter. Methods Choose the patients who are suffered from silent myocardial ischemia what were checkedout by 12 - lead 24 hours Hoher,at the period,do coronary angiography operation on these patients and compare with the Holter＇s results. At last, estimate the diagnosis and positioning accuracy of silent myocardi- al ischemia by 12 - lead 24 hours Hoher, Reaults 85 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. The coincidence rate is 85% between the positioning ischemie site of Holter and the blood - supply range of lesioned vessel by coronary angiography. Conclusion 12 - lead 24 hours Holter can diagnosis silent myocardial ischemia, and position the ischemic site.
