中老年人心电图TV1〉TV5、V6与冠心病及心脏猝死相关性研究

Relative research on electrocardiogram Tv1〉Tv5 and v6 with sudden cardiac death and coronary heart disease in middle -aged and aged people

目的探讨心电图Tv1〉Tv5、v6的临床意义。方法在7017例正常健康体检人群中，检出所有心电图无其他异常、仅有Tv1〉Tv5、v6者，与心电图正常组对比，并在其后13年中随访。结果Tv1〉Tv5、v6发生率为0．56％，伴高血压病增多占41％，均见于50岁以上者。随访发现，13年后高血压病、心肌缺血、心肌梗死、心脏性猝死率异常组明显增高，分别为74．3％、54．3％、8．6％、11．4％，高于正常组的5．0％、2．4％、0、0，也高于我国人群的11．9％、6．5％、0．06％、0．009％，差异有统计学意义（P〈0．01）。结论中老年人Tv1〉Tv5、v6者随年龄增长与高血压病、冠心病、心脏性猝死呈密切的相关性，应引起临床的高度重视。

Objective To investigate the clinical significance of electrocarocardiogram （ECG） Tv1〉Tv5 and Tv6. Methods Among the physical examinations in 7 017 cases, to select whose ECG were normal except for Tv1〉Tv5 and Tv6 and compared with ECG normal group, and continuously investi- gate in the following 13 years. Results The incidence rate of Tv1〉Tv5 and Tv6 was 0.56% , patients with hypertension increased to 41% , all can be seen in the group of patients over 50 years old. After the 13 years of follow -up investigation, incidence rate of hypertension, myocardial ischemia, myocardial infarction and sudden cardiac death were apparently increased by 74.3% , 54.3% , 8.6% , 11.4% respectively, comparatively higher than those of the normal group by 5.0% ,2.4% ,0,0, also, comparatively higher than those of Chinese people by 11.9% , 6.5% , 0.06% , 0. 009% ,which were significant differences （P 〈 0. 01 ）. Conclusions It is suggested that, the fact Tv1〉Tv5 and Tv6 among middle - age and aged people are significantly correlated with hypertension and coronary heart disease with age, should receive great clinical attention.
