摘要
目的探讨心电图持续性ST-T改变与慢性冠状动脉供血不足之间的关系。方法对158例心电图持续性ST-T改变的患者进行选择性平板运动试验和冠脉造影。结果54例平板运动试验阳性(34.2%),104例平板运动试验为阴性(65.8%)。冠脉造影发现冠状动脉狭窄者36例(22.7%)。平板运动试验阳性者中33例有冠状动脉狭窄,占冠状动脉狭窄病例91.6%。结论静息心电图持续性ST-T改变并非慢性心肌缺血的特异性改变,而绝大多数即是由其他原因所引起。
Objective To explore the relationship between the ST-T continuous changes of ECG and the chronic coronary insufficiency. Methods 158 cases of ST-T continuous changes of ECG were treated with selective plate exercise tests and the coronary arteriography. Results 54 cases of plate exercise tests were positive（34.2 % ）, 104 cases were negative（65.8 % ）. 36 cases were diagnosed as the stenosis of coronary through the coronary arteriography（22.7 % ）. But among 54 positive cases of plate exercise tests, 33 cases had the stenosis of coronary, accounting for 91.6 % in the cases of stenosis of coronary. Conclusion The quiescent ECG ST-T continuous changes aren＇t specfic changes of chronic myocardial ischemia. Most of them are caused by other reasons.
