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。 This paper investigates and analyzes the high-frequency electrocardiogram of 183 middle-aged and elderly people, with an average age of 60.38 years, of which 72.13% are 50-69 years old. The results showed that: (1) There was no significant difference in the number of high-frequency notch between men and women; (2) The increase of high-frequency components in V_1 and V_2 leads the possibility of considering the possibility of anterior wall anterior descending coronary artery Sexuality, on the other hand can remind the heart of the positive posterior wall; (3) in this survey of all age groups, according to the number of high-frequency notch, preliminarily saw the peak age of onset of ischemic heart disease In the 50 to 70 years old; (4) high-frequency electrocardiogram of ischemic heart disease sensitivity 40% higher than conventional ECG; (5) In addition, the examination of the 9 lead method used by both maintaining 6 Joint sensitivity, but also on the positioning of heart disease diagnosis provides a reference value.
