摘　　要：本文调查和分析183名中老年人的高频心电图,其平均年龄为60.38岁,其中50～69岁者占72.13％。结果显示:(1)男女之间的高频切迹数目无明显差异;(2)V_1、V_2导联上高频成分的增多,一方面需考虑右冠状动脉前降支引起前间壁病变的可能性,另一方面可提醒对心脏正后壁的重视;(3)在本次调查的各年龄组中,依其高频切迹之数目,初步看出了缺血性心脏病的发病年龄高峰在50～70岁之间;(4)高频心电图对缺血性心脏病的敏感性比常规心电图高40％;(5)此外,这次检查所采用的9导联方法既保持了6导联的敏感性,又可对心脏疾病的定位诊断提供参考价值。The purpose of this study was to investigate and analyze the high frequency electrocardiogram (HFECG) for middle-aged and elderly people.138 subjects were chosen in our study.The mean age was 60.38 years.Among them,72.1 per cent were between 50 and 69 years.The results showed that (1) the differences were not significant between male and female groups in the mean number of high frequency notches (HFN).(2) For an increase in high frequency notches in the leads V1 and V2,we should consider the possibility of pathological changes of the anterior medial wall of heart,which was supplied by the dessending rami of the right anterior coronary artery,on the one hand,and it might remind us to pay great attention to posteromedian wall of heart,on the other hand.(3) Looking at all age groups in this study,we preliminarily found that the age peak of ischemic heart disease was between 50 and 70 years,according to the number of high frequency notches in the leads of HFECG.(4) The sensitivity of HFECG for diagnosing ischemic heart disease is 40 per cent higher than that of the conventional ECG.(5) In addition,nine leads were used in this examination,which not only preserved sensitivity of six leads but also could provide a localizing value for the diagnosis of heart disease.
