- 摘要:
- 本文探讨运动性QRS波高频电压改变及临床意义。36例心肌梗死, 45例心绞痛, 52例胸闷,57例康复者及48例正常人, 共238例, 分别于运动前后进行了常规心电图和高频心电图检测。运动后, 常规心电图有改变者很少, 而高频心电图每例都有明显改变; QRS波高频电压, 在冠心病患者中是下降的, 在正常人中是上升的, 两者差异非常显著(P<0.01)。这表明, 运动性QRS波高频电压改变, 可作为心肌是否缺血的参考指标, 其敏感性高达100% , 特异性可达87.5%。
- Abstract:
- This study was to assess the clinical significances of the changes of high frequency voltage(HFV) in the QRS complex induced by exercise. 238 cases were examined with HFECG before and after exercise, respectively.They were classified into 5 groups:Myocardial infarction (n=36), angina pectoris (n=45) , chest discomfort (n=52),recovery(n=57) and normal(n=48).After exercise, HFV is decreased in coronary heart disease(CHD ),but is increased in normal.The diferences after exercise among these groups are very significant(P<0.01).The results show that the changes of HFV in the QRS complex induced by exercise may be used as a diagnosis index of CHD, its sensitivty and specificity are 100% and 87.5% , respectively.
