双腔频率适应性起搏器对病态窦房结综合征老年患者心功能和生活质量的影响

Influence of dual-chamber rate adaptive pacemakers on cardiac function and quality of life of elderly patients with sick sinus syndrome

目的:探讨双腔频率适应性起搏器对病态窦房结综合征老年患者心功能和生活质量的影响效果。方法:收集病态窦房结综合征老年患者40例,随机分为对照组和实验组(各20例),对照组给予双腔非频率适应性起搏器治疗,实验组给予双腔频率适应性起搏器治疗,比较2组患者治疗前、后心功能及生活质量变化。结果:实验组患者术后6个月LVEF、6-MWT和BNP水平与对照组存在显著性差异(均P<0.01);2组患者治疗后心功能等级分布存在明显差异(P<0.05);实验组患者术后6个月生理机能、生理职能、精力、精神健康与总体健康评分与对照组存在显著性差异(均P<0.01)。结论:双腔频率适应性起搏器对病态窦房结综合征老年患者心功能和生活质量的影响效果显著,并优于双腔非频率适应性起搏器。

Objective： To investigate the influence of dual-chamber rate adaptive pacemakers on cardiac function and quality of life of elderly patients with sick sinus syndrome. Methods： Forty elderly patients with sick sinus syndrome were collected and randomly divided into two groups（ 20 cases each）. The patients in the control group were given a non-dual-chamber rate adaptive pacemaker,and those in the experimental group received dual-chamber rate adaptive pacemaker. Before and after treatment,heart function and quality of life were compared. Results： There were significant differences in LVEF,6-MWT and BNP levels between two groups at 6th month after treatment（ all P〈0. 01）. After treatment,there was significant difference in cardiac function grade distribution between two groups（ P〈0. 05）. At 6th month after treatment,physiological function,physical function,energy,mental health and overall health score showed significant difference between two groups（ all P〈0. 01）. Conclusion： The effect of dual-chamber rate adaptive pacemakers on cardiac function and quality of life of elderly patients with sick sinus syndrome was significant,and better than the non-dual-chamber rate adaptive pacemakers.
