摘  要:目的:探讨老年男性冠心病患者无症状心肌缺血(SMI)的动态心电图特点。方法:对198例老年男性冠心病患者进行动态心电图检查。结果:老年男性冠心病患者常规心电图心肌缺血检出率低(18.69%),动态心电图心肌缺血检出率高(65.15%),主要为SMI;SMI发生高峰为上午8时,日间SMI发生明显多于夜间;睡眠及日间休息时SMI平均持续时间较活动时明显延长(P<0.05)。结论:老年男性冠心病患者SMI发生率高,其发生和持续时间有一定的规律,动态心电图是冠心病患者SMI的重要检测和评估手段。Objective: To study the character of silent myocardial isehemia (SMI) attacking in gerontal patients with coronary heart disease (CHD). Methods: The 24 h dynamic electrocardiogram monitoring was performed in 198 gerontal male CHD patients. Results: The occurrence rate of the myocardial ischemia in gerontal male CHD patients detected by ECG was lower (18. 69%), but detected by DCG was higher and mainly free of syndromes. The peak of occurrence of SMI was at 8 o'clock AM, SMI occurs obviously more often at daytime than at nighttime. The duration of SMI was significantly longer at sleeping time and rest time than at acting time (P〈0.05). Conclusion: The occurrence rate of SMI in gerontal male CHD patients is higher. DCG is an important means of detection and evaluation for SMI in CHD patients.
