摘要 目的探讨QuickOpt算法对心脏再同步治疗(CRT)患者术后房室和室室间期优化的价值。方法 13例符合CRT植入Ⅰ类适应证的慢性充血性心力衰竭患者,植入具有QuickOpt功能的CRT起搏器,术后6个月随访,分别采用QuickOpt算法和超声法优化得出两种房室和室室间期,再分别测定并比较不同算法下患者左心室射血分数(LVEF)、左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)、左心房内径(LAD)、左心室收缩末期容积(LVESV)、主动脉运动流速时间积分(AVTI)、二尖瓣返流面积(MRA)、QRS波宽度(QRSd)、主肺动脉射血时间差(IVMD)和径向应变延迟指数(RSDI)之间的差异。结果 13例CRT患者在QuickOpt算法所得房室和室室间期下随访6个月后发现,患者LAD、LVEDD、LVESD、LVEDV、LVESV、QRSd、MRA和IVMD较术前1周降低,LVEF、RSDI较术前1周提高(P<0.05)。QuickOpt算法优化后的房室间期较超声法优化后的偏长(P<0.05),室室间期无统计学差异(P>0.05);两种方法优化后的室室间期具有较好的一致相关性(r=0.906,P<0.01)。结论 QuickOpt算法简单便捷,可准确指导CRT患者术后房室和室室间期优化,改善患者心室同步性和心功能。
