Objective It is to explore the predictive value of giant negative twave in resting electrocardiogram for the diagnosis of coronary artery.
目的探讨静息心电图巨大倒置T波在冠心病诊断中的预测价值。
2
Conclusion During moment of coronary angiography, rised pressure of coronary artery and short_lived myocardial ischemia might lead to abnormal QRS _ wave and change of ST _ t in ECG.
结论冠状动脉造影瞬间冠状动脉压力升高、短暂心肌缺血，可引起心电图QRS波群及ST_T的异常改变。
3
Conclusion Symmetrical and giant negative twave not complicating with left ventricular hypertrophy in electrocardiogram has a predictive value for coronary heart disease.
