Summary

This trial compares three common heart-rate-lowering drugs—metoprolol, atenolol, and ivabradine—to see which one reduces heart rate fastest before a cardiac CT scan. About 350 adults aged 30–80 with a heart rate over 65 beats per minute will receive one of the drugs or a placebo. The goal is to improve scan quality by quickly achieving a lower heart rate.
