摘　　要：目的:探讨动态心电图(DCG)对监测心肌缺血,特别是老年无症状心肌缺血(SMI)的价值。方法:分析我院280例老年冠心病患者(有症状与无症状心肌缺血组)的DCG和临床资料。结果:静态心电图检出心肌缺血85例(30.5%),DCG检出心肌缺血180例(64.4%);SMI检出率为67.8%,有症状心肌缺血检出率为29.9%;两组患者在心肌缺血发作持续时间及ST段下降幅度方面差异无显著性;心肌缺血的发作及发作时伴发心律失常有明显的时间分布规律,均以6:00~12:00时为多见,以0:00~6:00时最为少见;无症状组恶性心律失常发生率明显高于有症状组。结论:DCG对SMI检出率高,有助于对老年冠心病的病情评估和早期防治。Objective To study the value of dynamic electrocardiogram(DCG) applying in myocardial ischemia(SMI) especially in subclinical myocardial ischemia(SMI). Methods DCG and clinical data of 280 coronary heart disease(CHD) patients with clinical myocardial ischemia(CMI) or SMI were analyzed. Results 85 Case (30.5%) of MI were detected by electrocardiogram(ECG), 180(64.4%) by DCG. The isolating rate 67.8% was SMI, 29.9% was MI. Incidence rate of malignant arrhythmia of SMI is more higher than CMI. Conclusion DCG h...
