摘要
目的对比植入第二代无导线起搏器(Micra AV)与传统双腔起搏器所致患者辐射剂量。方法回顾性分析74例因心动过缓接受植入起搏器患者,按照植入起搏器类型将其分为AV组(n=30)与传统组(n=44);比较2组透视时间、空气比释动能(AK)、剂量面积乘积(DAP)、电影序列数及电影合计帧数。结果AV组AK、电影DAP、电影序列数及电影合计帧数均高于传统组(P均<0.05);组间透视时间和透视DAP差异均无统计学意义(P均>0.05)。2组患者X线辐射投射范围基本一致,且多分布于躯体左半侧。结论相比植入传统双腔起搏器,植入Micra AV时患者所受电影采集辐射剂量更大,而透视所致辐射剂量无显著差异。
Objective To compare patient radiation dose during implantation of the second generation wireless pacemaker(Micra AV)and traditional dual-chamber pacemaker.Methods Data of 74 patients who received pacemaker implantation for bradycardia were retrospectively analyzed.According to the kind of pacemaker,the patients were divided into AV group(n=30)and traditional group(n=44).The perspective time,air kerma(AK),dose area product(DAP),number of movie sequences and total movie frames were compared between groups.Results AK,movie DAP,number of movie sequence and total movie frames in AV group were all higher than those in traditional group(all P<0.05).No significant difference of the perspective time nor perspective DAP was found between groups(both P>0.05).Patients’X-ray radiation projection range were essentially the same in both groups,most distributing on the left side of the bodies.Conclusion Compared with implantation of traditional dual-chamber pacemaker,implantation of Micra AV brought patient greater radiation dose from movie acquisition,while radiation dose from fluoroscopy were not significantly different.
