Methods patients were randomly assigned to electrocardiogram ST section change group(A) or pure T wave change group(B), receiving coronary angiography.

方法按照病人的心电图ST段压低或抬高和单纯T波改变者分为A、B两组，行冠脉造影。

Objective To evaluate the relationship between t wave change and coronary recanalization in patients who accepted intravenous thrombolytic therapy for acute myocardial infarction.

目的探讨急性心肌梗塞溶栓后早期T波的变化与闭塞冠脉再通的关系。

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。

Of course, like many organisations, it will have growing pains and management issues and communication issues but it is an organisation that has 194 countries subscribing to it, so we can't just wave a magic wand and change things.
