摘要
目的探讨老年人无症状心肌缺血(SMI)的动态心电图特点及临床意义。方法1109例干部体检常规心电图发现心肌缺血323例,经24小时动态心电图(DCE)检查,按年龄分两组(≥60岁为老年组,<60岁为对照组)进行分析讨论。结果323例中SMI有225例(占69.66%),SMI发生率老年组较对照组高,SMI发生时间、诱发因素、频率依赖性老年组与对照组不同(P<0.05)。结论老年人的SMI发生率较高,多发生于傍晚和夜间,发病前多无明显诱因。动态心电图在早期发现SMI有可靠的诊断价值及重要的临床意义。
Objective To explore the feature and clinical significance of the dynamic electrocardiogram on the senile patients with silent myocardial ischemia.Methods In the medical examination of the 1109 cases,323 cases were diagnosed myocardial ischemia.Through the examination of the 24 hours dynamic electrocardiogram,the cases were divided into two groups according to the age,the elder group ≥60 years old,the control group 〈60,then,we analysed and discussed the result.Results 323 cases were diagnosed with myocardial ischemia,and 225 cases were diagnosed with SMI among them（69.66﹪）.About the incidence of SMI,the elder group was higher than the control group,there were differences in two groups on the time of occurrence,causative factor and frequency dependence.To compare the parameter,there was significant deviation（P 〈 0.05）.Conclusions The incidence rate of the senile patients on SMI was high,and the morbility was high at night.Before the illness,the incentive was rare.The dynamic electrocardiogram showed the reliable diagnostic value and considerable clinical significance for the early discovery of the SMI.
