摘要 目的本研究采用不同部位的右心室起搏,观察各组起搏后QRS波时限及血浆心房利钠肽(ANP)的变化。方法将60例植入起搏器患者分为右室心尖部(RVA)组、右室间隔部(RVS)组和对照组,各20例。测量术后的心电图QRS波时限,分别测定患者术前、起搏1周及起搏3个月后静脉血浆ANP,比较不同时期不同起搏方式下ANP水平变化。结果术后RVS组和RVA组QRS波时限分别为(112.25±15.02)ms、(146.95±20.27)ms,两组比较有统计学意义(P<0.01)。术后3个月ANP水平,RVS组为(144.97±29.07)pg/mL,RVA组为(220.89±40.96)pg/mL,对照组为(132.68±23.13)pg/mL。RVA组与RVS组的差别有统计学意义(P<0.01)。RVS组术后3个月ANP水平与RVA组比较差异有统计学意义(P<0.01);对照组术后3个月ANP水平较RVA组低;对照组与RVS组比较差异无统计学意义(P>0.05)。结论RVS起搏QRS波时限较RVA起搏窄。
