摘要
目的:研究心腔内心电图引导的心脏同步化治疗优化的可行性。方法入选23例患心脏再同步化治疗患者,根据自身体表心电图QRS波宽度分为A组(QRS波宽120~150ms )、B组(QRS波宽>150ms ),术后1~2周行传统心脏超声引导优化和心腔内心电图引导的优化。比较两者优化结果的相关性。结果 A、B两组应用传统心脏超声优化和心腔内心电图引导的优化的房室间期相关性良好( r^2分别为0.87和0.95)。A组双心室间期(VV间期)相关性不佳( r^2=0.19,P>0.05),B组相关性良好( r^2>0.05,P<0.01)。结论左心室内机械失同步化为主(心室间电生理同步性)患者中应用心腔内心电图引导的优化的可行性有待进一步研究。
Objective To study the feasibility of ECG guiding optimization for cardiac resynchronization therapy.Methods 23 patients who underwent cardiac resynchronization therapy were enrolled in this study.According to the self QRS wave width ,they were divided into two groups:Group A(120-150ms) and group B(〉150ms).The optimization of cardiac resynchronization therapy guided by ECG and Echocardiogram were taken two weeks after operation.The correlation of AV/PV and VV interval of the two methods was analyzed. Results Data analysis showed the tight correlation between the echocardiogram and the ECG method ,and the correlation in-dex(CI) was 0.87 and 0.95 respectively.The correlation of VV optimization in group A ( r^2=0.19 , P〉0.05)is not as well as group B( r^2=0.99 , P〈0.01) .Conclusions The feasibility of ECG guiding optimization for cardiac resynchronization therapy needs further research ,especially ,in patients who with intra-left ventricular mechanical asynchrony but absence of inter-ventricular electri-cal asynchrony.
