频率适应性起搏在老年病窦伴变时功能不全患者中的疗效观察

摘要

Objective Clear rate adaptive pacing can improve elderly sick sinus syndrome (SSS) patients with chronotropic incompetence patients’ quality of life, exercise capacity and cardiac function.Methods 60 cases of sick sinus syndrome with clinical data of elderly patients with chronotropic incompetence were retrospectively analyzed. The preoperative evaluation and postoperative 6 month and 12 months after the operation of ultrasonic cardiogram, 6 minutes walk test (6-MWT) and quality of life (QOF) check. Left ventricular end diastolic diameter (LAEDD), left ventricular end diastolic diameter (LVEDD) and ejection fraction (LVEF) were observed by echocardiography.Results LVEF, 6-MWT and QOF were signiifcantly improved compared with preoperative and DDD pacing, and there were signiifcant differences between DDDR and pacing. LAEDD and LVEDD were not signiifcantly different before and during DDD pacing and DDDR pacing.Conclusion The rate adaptive pacing (DDDR) can signiifcantly improve the elderly sick sinus syndrome with varying quality of life dysfunction and exercise tolerance, and can improve the ejection fraction, but did not reduce heart cavity structure. Therefore, the elderly patients also need to implant frequency adaptive pacing.%目的：明确频率适应性起搏是否能改善老年病态窦房结综合征(SSS)伴变时功能不全患者的生活质量、运动能力以及心功能。方法对60例病态窦房结综合征伴心脏变时功能不全的老年患者的临床资料进行回顾性分析，评估其术前、术后6个月及术后12个月的超声心动图、6分钟步行试验（6-MWT）及生存质量(QOF)检查。其中心脏超声观察左房舒张末期内径（LAEDD）、左室舒张末期内径(LVEDD)及射血分数(LVEF)。结果 DDDR起搏时LVEF、6-MWT以及QOF较术前及DDD起搏明显提高，有显著差异。术前、DDD起搏及DDDR起搏,LAEDD、LVEDD均无明显差异。结论频率适应性起搏（DDDR）能显著改善老年病态窦房结综合征伴变时功能不全的患者的生活质量及运动耐量，同时能提高射血分数，但并不能减小心腔结构。因此，老年患者同样需要植入频率适应性起搏。
