RESULTS: After ligation of coronary arteries, rates of heart electrical alternans of QRS waves, ST segment and T wave were 92%, 81% and 62%, respectively. 结果:结扎冠脉后,QRS波群、ST段及T波电交替的发生率分别为92%,81%及62%。
Conclusion: Temporary coronary artery spasm was not necessarily accompanied by ST segment elevation. Changes of ST segment were correlated to severity of coronary artery stenosis induced by spasm. And tall peaked T wave was more sensitive than ST segment in the detection of coronary artery spasm. 结论:短暂性冠状动脉痉挛不一定伴有ST段抬高,ST段变化与冠状动脉痉挛程度有关,而T波高尖町能比缺血性ST段改变更敏感。
Results Coronary recanalization rate in T wave inversion group and T wave upright group was 93.1% and 11.3% respectively ( P < 0.01). 结果T波倒置组与未倒置组血管再通率分别为93.1%和11.3%(P<0.01)。
Conclusion The absence of left ventricular hypertrophy and the presence of symmetric T-wave inversion suggest the presence of coronary artery disease in those with giant negative T wave. 巨大负性T波患者心电图缺乏左心室肥厚较对称性T波倒置对冠心病更有预测价值。结论心电图巨大负性T波患者不伴左心室肥厚或对称性T波倒置是预测冠心病的重要因素。
The coronary angiography was performed on those patients with positive treadmill test or T wave change in ECG. 对运动试验阳性及心电图有T波变化的高血压病、冠心病患者进行冠状动脉造影。
