摘　　要：目的探讨无抽搐电休克治疗对心室复极的影响,评价治疗过程中心脏事件的安全性。方法对108例精神病人无抽搐电休克治疗前30分钟内和治疗后10分钟内进行心电图检查,对测量得出的校正QT间期(QTc)、Q-T离散度(Q-Td)、校正QT离散度(Q-Tcd)进行比较分析。结果治疗前Q-Tc、Q-Td、Q-Tcd[(418.01±27.97)ms、(36.07±18.38)ms、(42.33±21.54)ms]与治疗后[(424.09±40.34)ms、(50.4±16.49)ms、(63.38±21.64)ms]比较差异均有统计学意义(P<0.05)。结论无抽搐电休克治疗会使Q-Tc延长、Q-T离散度增大,可能增加患者心脏事件的风险。Objective To investigate the impact of MECT on Ventricular repolarization,evaluate the risk cardiac events in the course of MECT. Methods 108 patients with mental disorders were checked electrocardiogram in 30 minutes before MECT,then 10 minutes after MECT,check them again. Analysis their Q-Tc、Q-Td、Q-Tcd. Results Pre-mect,the Q-Tc、Q-Td、Q-Tcd is( 418. 01 ± 27. 97) ms,( 36. 07 ± 18. 38) ms,( 42. 33 ± 21. 54) ms],and post-mect,is( 424. 09 ± 40. 34) ms,( 50. 4 ± 16. 49) ms,( 63. 38 ± 21. 64) ms,( P < 0. 05). Conclusion MECT would increase Qtc interphase and Q-T dispersion,this suggest those patients with relong Q-Tc interphase or increased Q-T dispersion pre-MECT have risk of cardiac events.
