目的探讨右室心内膜心尖部起搏和右室间隔部起搏对儿童患者心功能的影响。方法选择2006年1月—2015年1月39例植入心脏人工永久起搏器的儿童患者,根据心室电极植入部位分为心尖部起搏(RVA组)(18例)和右室间隔部(RVS)组(21例)。随访18个月。观察两组患者术中、术后18月电极参数(感知、阈值、阻抗)的变化;比较两组患儿术前,术后18月心脏彩超,脑钠肽(BNP)数据,分析不同的起搏部位对心功能的影响。结果分析两组患者术中、术后18月电极参数,两组间数据无差异性(P>0.05)。两组患者心脏左室射血分数(LVEF),心输出量(CO),比较均无统计学差异(P>0.05)。BNP比较存在统计学意义(P<0.05)。结论儿童患者心尖部和室间隔起搏各项参数均较好。随访中未出现心脏功能降低。
Objective To investigate the influence of right ventricular endocardial apical pacing and right ventricular septal pacing on cardiac function in children. Methods From January 2006 to January 2015, 39 children implanted with artificial heart pacemakers were divided into atrial pacing (RVA) group (18 cases) and right ventricular septum (RVS) group (21 cases). Follow-up 18 months. The changes of electrode parameters (perception, threshold, impedance) during the operation and 18 months postoperatively were observed. The data of echocardiography and BNP before and 18 months after operation were compared between the two groups Impact of stroke site on cardiac function. Results The electrode parameters of the two groups were analyzed intraoperatively and postoperatively in 18 months. There was no significant difference between the two groups (P> 0.05). There was no significant difference in left ventricular ejection fraction (LVEF) and cardiac output (CO) between the two groups (P> 0.05). BNP was statistically significant (P <0.05). Conclusion All the parameters of apex and ventricular pacing in children are better. Follow-up did not appear to reduce cardiac function.
