| 摘 要： | 目的 探讨起搏器植入患者起搏前后QT离散度 (QTd)的变化。方法 采用美国产十二导联心电图仪同步记录 ,计算分析两组不同起搏方式QTcd(其中VVI起搏组 30例 ,DDD起搏组 19例 )的QTd变化。结果 以DDD起搏方式明显优于VVI起搏方式 ,起搏后 2～ 3天 ,DDD起搏组的QTcd较VVI起搏组明显减少 (t =2 .14 ,P <0 .0 5 )。结论 DDD起搏方式保留良好的房室顺序起搏 ,起搏后血流动力学改善 ,心肌复极趋于一致性 ,心电活动稳定。

| Abstract: | Objective To investigate the changes of QT dispersion (QTd) before and after cardiac pacing in patients receiving artificial pacemaker implant.Methods An American 12-lead surface electrocardiogram (ECG) instrument was used to simutanously record the QTcd changes. Then the changes of QTd in QTcd of different pacing mode in Group A and B (Group A: 30 cases of VVI pacing group; Group B: 19 cases of DDD pacing group) were caculated and analyzed.Results DDD pacing mode was obviously better than VVI pacing mode. 2～3 days after cardiac pacing, QTcd in Group B decreased more significantly than that in Group A (t=2.14, P<0.05).Conclusions DDD pacing mode could retain good atrioventricular sequential pacing, improve post-pacing hemodynamics, make the myocardial repolarization tend to be uniformity and keep the stability of cardioelectric activity. |
