Abstract Objectives The aim of this study was to evaluate the impact of a new ultra low-dose radiation protocol on radiation doses, feasibility and safety during electrophysiological device implantation. Background Radiation is one of the main hazards during electrophysiological procedures. Shielding is especially difficult during device implantation and particularly implantation of cardiac resynchronisation therapy devices (CRT) is associated with high radiation doses. Methods From January 2005 to January 2019, 8612 patients underwent de novo device implantation at our University Heart Center. During 2018, we established a new ultra low-dose radiation protocol and compared 661 patients who were treated during 2017 utilizing the conventional low-dose protocol with 512 patients after the application of the new program (11.5% one-chamber devices, 68.5% two-chamber devices and 19.9% CRT). Results After establishment of the radiation reduction protocol, dose area products could be reduced by 62% and the effective doses by 59% (113 (47–292) vs. 43 (14–130) cGycm2, p
