【摘要】 目的：探讨运动康复对急性心肌梗塞（AMI）患者预后的影响。方法：观察了40例作运动康复治疗的AMI患者（康复组）康复前后心电图Q－T离散度（Q－Td）的变化，并与未行运动康复的AMI患者（对照组）进行了比较。结果：运动康复后Q－Tcmax、Q－Td和Q－Tcd（校正Q－T离散度）三项指标均比运动康复前明显减少（P＜0．05或＜0．01）。并且患者出院时康复组Q－Td比对照组显著减少。结论：运动康复能够降低AMI患者Q－T离散度，可改善病人的预后。更多还原

【Abstract】 Objective: In order to investigate effect on prognosis of patients with acute myocardial infarction by exercise rehabilitation. Methods: The changes of Q-T dispersion in 40 cases with AMI were observated before and after exercise rehabilitation (rehabilitation group). Meanwhile, rehabilitative group was compared with no rehabilitation group (control group, 38 cases). Results: Q-Tcmax. Q-Td and Q-Tcd were decrease remarkably after exercise rehabilitation (P<0. 05 or P<0. 01 ). When patients dischaged from hospital, Q-T cmax. Q-Td and Q-Tcd more reduced in rehabilitation group than control group. Conclusion: Cardiac rehabilitation may reduce Q-T dispersion in patients with AMI and improve their prognosis.author’s address: Department of cardiology, First Affiliated Hospital, Medical College of Jiamusi University, Jiamusi. 154002更多还原
