摘要 目的评估植入双腔起搏器后行最小化心室起搏(MVP)和抗快速性房性心律失常(AT)对慢快综合征(BTS)患者的治疗价值。方法对48例有明显症状的BTS患者在双腔起搏器植入术后即刻予程控延长房室间期行MVP和抗AT为主要方案的治疗,通过动态心电图、超声心动图、6min步行距离等观察采用自身对照比较患者的房性心律失常发生率、生活质量、住院率和心功能等结果。结果随访2年,5例患者AT消失,4例转为慢性房颤,余39例AT平均发作次数从术前(26.12±3.67)次/月降至术后24个月时(7.85±2.72)次/月(P<0.01),AT平均持续时间从术前(2.05±3.36)h/d降至术后24个月时(0.35±1.25)h/d(P<0.05)、AT相关的住院率显著减少[(3.6±1.91)次/年vs.(0.55±1.82)次/年,P<0.01]、心输出量显著升高(P<0.05),6min步行距离显著延长(P<0.05)。结论 MVP通过预防心动过缓,改善房室收缩同步性,提高心输出量,可显著减少AT发作,降低住院率,提高患者生活质量。
