Summary

This study was designed to see if using an ultra-low X-ray pulse rate (3.75 frames per second) instead of the standard low rate (7.5 frames per second) could reduce the radiation exposure that cardiologists receive while performing coronary angiography through the right wrist. The trial planned to measure radiation at the doctor's chest and eyes, but it was withdrawn before any participants were enrolled, so no results are available.
