摘　　要：目的探讨冠心病冠状动脉内支架术（PCI）后心电图动态变化。方法分析比较38例冠心病PCI后1周、3周、2个月、3个月后不同时间段12导联心电图变化规律。结果与术前心电图比较，T波低平、双向发生在术后第1周明显增多并持续至2—3周后（5．0％，9．6％比2．6％，P〈0．05）。ST段抬高在术后第1周增多（P〈0．05），而后逐渐回落。sT段下移〉1．0mm和T波倒置在PCI术后第3周，第2月显著增多（5．0％和5．7％比2．6％；18．0％和25．2％比16．2％，均P〈0．05），继而ST段下移者减少到PCI术前水平；T倒显著减少（P〈0．01）。结论冠心病患者PCI术后，常伴出现早期一过性异常Q波、T波改变（倒或低平、双向）ST段下移等变化。心肌梗死患者冠脉再通后一过性ST段抬高。而后，上述改变时间逐渐恢复至术前水平。Objective To explore the dynamic changes of electrocardiography（ECG） in patients with coro： nary heart disease（CHD） after the percutaneous coronary intervention（PCI）. Methods To compare and analyze the regularity of the changes of 12-lead EGG on 38 cases in times, including one week, three weeks, one month, two and three months after the PCI Results Compared with the ECG before the operation,the occurrences of the low-lying or the bidirectional T-wave were significantly increased, and lasting to 2 - 3 weeks after the operation （5.0% and 9.6% vs2.6% ,P 〈0.05）. The ST segment depression（ 〉 1.0mm） and inverted T-wave in the 3 weeks and 2 months after the operation were significantly increased（5.0% ,5, 7% vs 2.6% ,P 〈 0. 05 ; 18.0% and 25.2% vs 16. 2% ,P 〈 0. 01 ）. After that,the eases of ST segment depression were reduced to the level before PCI,and there was a significant reduction in the cases of the inverted T-wave （P 〈 0. 01 ）. Conclusions In the ECG of the patients with CHD after PCI,there were always early one-off abnormal Q-wave,changes of T-wave（ inverted or low-lying,bidirectional）and ST segment depressions, etc. After that, the changes above would turn back to the level before the operation.
