【摘要】：目的運用實時三維超聲心動圖評價房室順序型心臟起搏器的右心室間隔部(RVS)起搏及心尖部(RVA)起搏對房室傳導阻滯患者左心房收縮功能的影響。資料與方法 51例具備埋藏式心臟起搏器植入適應證的房室傳導阻滯患者采用擲硬幣法隨機分為RVS組31例和RVA組20例,應用實時三維超聲心動圖測定患者植入房室順序型心臟起搏器術(shù)前、術(shù)后1個月、3個月、6個月及12個月的左心房最小容積(LAVmin)、左心房最大容積(LAVmax)、左心房收縮前容積(LAVprep)、左心房總射血分數(shù)(LATEF)及左心房主動射血分數(shù)(LAAEF)。結(jié)果兩組LAVmin于術(shù)后3個月開始較術(shù)前和術(shù)后1個月降低(RVA組:t=2.97、2.74,P0.05;RVS組:t=3.24、2.86,P0.05);RVA組自術(shù)后6個月開始、RVS組自術(shù)后3個月開始,LAVprep均較術(shù)前縮小(RVA組:t=3.20,P0.05;RVS組:t=2.71,P0.05);兩組LATEF和LAAEF均于術(shù)后3個月開始較術(shù)前提高(RVA組:t=2.87、9.68,P0.05;RVS組:t=3.56、8.22,P0.05);RVS組術(shù)后6個月、12個月的LATEF和LAAEF均大于同時間點的RVA組(t=2.90、5.22、3.03、3.55,P0.05)。結(jié)論房室順序起搏有利于房室傳導阻滯患者左心房收縮功能的恢復,RVS起搏較RVA起搏可以更大幅度地提升患者左心房射血分數(shù)。
[Abstract]:Objective to evaluate the effects of RVS (right ventricular septum) pacing and apical RVA (apical) pacing on left atrial systolic function in patients with atrioventricular block (AVB) by real time three dimensional echocardiography. Materials and methods 51 patients with atrioventricular block (AVB) who had indications for implantation of implantable pacemakers were randomly divided into RVS group (n = 31) and RVA group (n = 20). Real time three dimensional echocardiography was used to determine the preoperative implantation of sequential atrioventricular pacemakers. At 1 month, 3 months, 6 months and 12 months after operation, the minimum volume of left atrium (LAVmin), the maximal volume of left atrium (LAVmax1), the presystolic volume of left atrium (LAVprepen), the total ejection fraction of left atrium (LATEFF) and the left atrial active ejection fraction (LAAEF1) were measured. Results LAVmin in both groups were lower than those before operation and one month after operation. In RVS group, LATEF and LAAEF were decreased from 3 months after operation to 2. 72.72.74% and 3 months after operation. Both LATEF and LAAEF in RVS group were reduced by 3 months after operation, and LATEF and LAAEF in RVS group were all decreased by 3 months after operation compared with those in RVS group before operation. The LATEF and LAAEF in RVS group were 3. 71a and 3. 71p 0. 05% P 0. 05%, respectively, after operation, 3 months after operation, both LATEF and LAAEF in RVVS group were reduced from 3 months after operation to that in RVS group (P < 0. 05). After 6 months of operation, the LATEF and LAAEF in RVA group were higher than those in RVA group at the same time point. The LATEF and LAAEF were higher than those in RVA group at the same time point (5.223.033.5N, P0.05P 0.05N). The results showed that the LATEF and LAAEF of RVS group were higher than those of RVA group at the same time point (P 0.05), and the LATEF and LAAEF of RVS group at 12 months after operation were higher than those of RVS group (P < 0.05). Conclusion the sequential pacing of atrioventricular pacing is beneficial to the recovery of left atrial systolic function in patients with atrioventricular block. Compared with RVA pacing, RVs pacing can significantly improve the left atrial ejection fraction in patients with atrioventricular block.
