摘　　要：目的应用实时三维超声心动图(RT-3DE)技术对比分析左束支区域起搏(LBBP)与右室流出道起搏LBBP患者25例(LBBP组)和RVOP患者22例(RVOP组)。应用RT-3DE获取两组患者术后1个月左室整体收缩功能参数即左室射血分数(LVEF)、左室每搏量(LVSV)、左室舒张末期容积(LVEDV)及收缩末期容积(LVESV),以及左室收缩同步性参数即左室达最小收缩容积时间的标准差(Tmsv-SD)、最大时间差(Tmsv-Dif)及经心率校正的标准差及时间差(Tmsv-SD%、Tmsv-Dif%),比较两组上述各参数差异。结果两组LVEF、LVSV、LVEDV、LVESV比较差异均无统计学意意义(均P<0.05)。结论 RT-3DE能定量评价LBBP患者和RVOP患者左室收缩同步性,且LBBP患者术后左室收缩同步性优于RVOP。ObjectiveTo compare and analyze the left ventricular global systolic function and synchrony in patients with left bundle branch area pacing(LBBP)and right ventricular outflow tract pacing(RVOP)by real-time three-dimensional echocardiography(RT-3DE).MethodsTwenty-five patients with LBBP(LBBP group)and 22 patients with RVOP(RVOP group)were enrolled in the study.The global systolic function parameters of the left ventricle,including left ventricular ejection fraction(LVEF),left ventricular stroke volume(LVSV),left ventricular end-diastolic volume(LVEDV),left ventricular endsystolic volume(LVESV)and systolic synchronic parameters(Tmsv-SD,Tmsv-Dif,Tmsv-SD%,Tmsv-Dif%)were obtained by RT-3DE.The differences of above parameters were compared between two groups.ResultsThere were no significant differences in LVEF,LVSV,LVEDV and LVESV between the LBBP group and RVOP group.Tmsv-SD,Tmsv-Dif,Tmsv-SD%,Tmsv-Dif%of 16,12,6 segments of left ventricle in LBBP group were lower than those in RVOP group,there were statistically significant differences(all P<0.05).ConclusionRT-3DE can quantitatively assess left ventricular systolic synchrony,and LBBP is superior to RVOP in left ventricular systolic synchrony.
