摘要
目的根据扩张型心肌病（DCM）患者对心脏再同步治疗（CRT）不同的反应性，对其心律失常的性质与数量进行临床观察。方法随机选取近年来90例随访资料完整的心脏再同步治疗起博器（CRT—P）或心脏再同步治疗除颤器（CRT-D）纳入分析，根据其反应性分为超反应组、有反应组及无反应组。并在CRT术后第6个月及1年随访时，进行临床评估、动态心电图及超声心动图评价。结果各组患者在基线状态除QRS时限、心力衰竭症状出现时问有明显差别外，其余参数在基线状态无明显区别。6个月及1年随访时超反应组的室性心律失常及房性心律失常均明显改善，无反应组则无明显变化。结论CRT能改善患者室性及房性心律失常的发生，特别是对于超反应者效果更明显。
Objective The purpose of this study was to investigate the arrhythmia in patients with cardiac resynchronization therapy （CRT-P/CRT-D） of DCM during follow-up. Methods Total 90 patients were included in our study, and were divided into three groups at 6 months after CRT, including suer-reponders, non-responders and responders. AT 6 months and 1 year after resynchronization therapy, we programed the de- vices, Holter, clinical and echocardiographic evaluation were performed. Results At baseline, there were no significant differences among three groups, excepting for the QRS duration, and duration of the onset of heart failure symptoms. After 6 months and 1 year, there were significant improvement in arrhythmia, QRS duration, LVEF and arrhythmias in super-responders. Conclusion Supper-responders patients with cardiac resynchroni- zation therapy had less arrhythmia.
