摘要
本丈分析了心电图正常的14例心绞痛病人的向量图T环改变,T/QRS<1/4,14例(100%),T环长/宽<2.5,12例(86%),QRS-T夹角增大8例(57%),而横面T环转向异常2例(14%),T环阳性征为2.6,故认为心电向量图T环异常对静息心电图正常的心绞痛病人可提供诊断帮助。
The change of vectorcardiogram T ring of normal electrocardiogram of 14 cases with angina pectoris was analysed: T/QRS<1/4 was 14 cases (100%), T ring length/width<2.5 was 12 (86%), QRS-T angle increased in 8 cases(57%), but the abnormal turn of transverse level T ring appeared in 2 cases (14%), T ring positive rate was 2.6. It is suggested that the abnormal vectorcardiogram T ring gives a useful clue to diagnosis of angina pectoris with quiescent normal electrocardiogram.
