【摘要】：目的比较右室不同起搏部位对老年病窦综合征(SSS)患者左心室收缩功能的影响。方法选取该院2014-2016年收治的78例SSS患者,按照右室不同起搏部位分为右室心尖部(RVA)起搏组(40例)和右室流出道(RVOT)起搏组(38例),比较术前、术后3个月和术后9个月两组起搏器QRS波时限、总计右心室起搏百分比和左心室收缩功能指标。结果两组患者术前QRS波时限和各项左心室收缩功能指标比较,差异均无统计学意义(P0.05)。术后3个月和术后9个月,RVA起搏组患者QRS波时限较RVOT起搏组长,差异有统计学意义(P0.05)。术后9个月两组总计起搏百分比比较,差异无统计学意义(P0.05);而RVOT起搏组左心室射血分数高于RVA起搏组,左心室舒张末内径小于RVA起搏组,差异均有统计学意义(P0.05)。结论 RVOT起搏对SSS患者左心室收缩功能的作用优于RVA起搏。
[Abstract]:Objective to compare the effects of different pacing sites of right ventricle on left ventricular systolic function in patients with senile sinus syndrome (SSS). Methods Seventy-eight patients with SSS from 2014 to 2016 were divided into right ventricular apex pacing group (n = 40) and right ventricular outflow tract pacing group (n = 38). The duration of pacemaker QRS wave, the percentage of right ventricular pacing and the index of left ventricular systolic function were measured 3 months after operation and 9 months after operation. Results there was no significant difference in QRS wave duration and left ventricular systolic function between the two groups (P 0.05). The duration of QRS wave in RVA pacing group was significantly longer than that in RVOT pacing group 3 months after operation and 9 months after operation, and the difference was statistically significant (P 0.05). There was no significant difference in the percentage of total pacing between the two groups 9 months after operation, but the left ventricular ejection fraction in the RVOT pacing group was higher than that in the RVA pacing group, and the left ventricular end-diastolic diameter was smaller than that in the RVA pacing group (P 0.05). Conclusion the effect of RVOT pacing on left ventricular systolic function in patients with SSS is better than that of RVA pacing.
