目的:分析冠状动脉血管病变与心电图慢性ST-T改变的关系。方法:对213例患者冠状动脉造影和心电图结果进行对比分析。结果:(1)135例患者心电图有慢性ST-T改变,其中冠状动脉造影阳性83例(61.48%),阴性52例(38.52%)。(2)78例患者心电图ST-T表现正常,冠状动脉造影阳性46例(58.97%),阴性32例(41.03%),2组比较差异无统计学意义(P>0.05)。结论:常规静息心电图慢性ST-T改变不能诊断冠心病。
Objective: To analyze the relationship between coronary artery disease and chronic ST-T changes in ECG. Methods: The coronary angiography and electrocardiogram results of 213 patients were analyzed. Results: (1) 135 cases of patients with chronic ST-T ECG changes, including 83 cases of coronary angiography positive (61.48%), negative in 52 cases (38.52%). (2) The electrocardiogram of 78 patients showed normal ST-T, 46 cases (58.97%) were positive coronary angiography and 32 cases were negative (41.03%). There was no significant difference between the two groups (P> 0.05). CONCLUSION: Chronic ST-T changes in conventional resting ECG can not diagnose CHD.
