【摘要】：本文报道了1例诊断为扩张型心肌病的患者,通过双腔起搏器单左心室起搏运用频率适应性房室延迟(RAAV)功能实现心脏再同步化治疗(CRT)。通过术后6个月随访,QRS波时限由术前170 ms变窄为术后118 ms,左心室舒张末内径(LVDd)由术前78 mm缩小为术后49 mm,左心室射血分数(LVEF)由术前32%升高为术后48%,心胸比由术前0.64减小为术后0.55,美国纽约心脏病学会(NYHA)心功能分级由术前Ⅲ级降低为术后Ⅰ级,左房室瓣反流面积(MRA)由术前14.0 cm~2减少为术后1.8 cm~2,左心室12节段达峰时间标准差(TS-SD12)由术前150 ms减少为术后77 ms,主、肺动脉射血时间差(IVMD)由术前47 ms改善为术后33 ms,达到超应答标准。同时结合文献复习,以提高临床医生对双腔起搏器通过RAAV实现双室收缩再同步的认识和应用。
