Safety and feasibility of a 1 frame-per-second X-ray framerate in cardiac electrophysiology.

Background: We investigated the feasibility and safety of a framerate of 1 frame per second ("fps") for fluoroscopy and cine-angiography, to lower radiation exposure for patients and personnel in cardiac electrophysiology ("EP").

Method: Analysis of 2521 EP procedures, 899 (36%) with the lowest available conventional framerate (3.75 fps) and 1622 (64%) procedures performed with a framerate lowered further to 1.
