Coronary CT angiography is commonly performed using beta blockers to slow the heart rate and reduce motion artifacts in the images, thereby improving diagnostic accuracy. Oral metoprolol is often prescribed one hour prior to the procedure. Intravenous metoprolol may be given immediately prior to the procedure as an alternative or if oral beta blocker alone did not achieve adequate heart rate control.
