摘　　要：目的分析急性心肌梗死(acute myocardial infarction,AMI)患者心电图复极相关参数的变化情况,并评估其对胸痛患者临床综合评估的指导作用。方法选取93例经冠状动脉造影证实的AMI患者(AMI组),同时选取年龄、性别与之匹配的正常对照组82例。比较两组心电图肢体导联和胸导联复极相关参数。结果 AMI组肢体导联QT间期、QTc间期和T波时间明显高于正常对照组[(387. 4±36. 9) ms vs.(370. 0±24. 7) ms;(422. 8±35. 6) ms vs.(405. 0±23. 0) ms;(174. 4±26. 8) ms vs.(167. 0±11. 0) ms],且差异均有统计学意义(P <0. 05)。胸导联QT间期、QTc间期和T波时间也明显高于正常对照组[(399. 3±44. 6) ms vs.(368. 9±24. 0) ms;(435. 0±37. 5) ms vs.(404. 2±23. 1) ms;(195. 0±30. 9) ms vs.(174. 9±12. 1) ms],且差异均有统计学意义(P <0. 05)。结论 AMI患者心电图复极时间延长。心电图复极相关参数的变化对胸痛患者的临床综合评估有一定的指导作用。Objective To analyze the change of indexes related to ECG repolarization in the patients with acute myocardial infarction(AMI), and to judge its instruction for clinical comprehensive evaluation in the patients with chest pain. Methods Ninety-three patients with AMI confirmed by coronary angiography were selected as AMI group while 82 normal controls were simultaneously selected. Cases and controls were matched in age and sex. The indexes related to repolarization in limb and chest leads were compared between the two groups. Results In the AMI group, the QT interval, QTc interval and T wave duration in limb leads were significantly higher than those in the control group[(387.4±36.9) ms vs.(370.0±24.7) ms;(422.8±35.6) ms vs.(405.0±23.0) ms;(174.4±26.8) ms vs.(167.0±11.0) ms] with statistically significant differences ( P < 0.05);the index values in chest leads were also significantly higher[(399.3±44.6) ms vs.(368.9±24.0) ms;(435.0±37.5) ms vs.(404.2±23.1) ms;(195.0±30.9) ms vs.(174.9±12.1) ms] with statistically significant differences( P <0.05). Conclusion The repolarization time is prolonged on the ECG of AMI patients. Variation of repolarization-related indexes are instructive for clinical comprehensive evaluation in the patients with chest pain.
