Abstract:
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.
