These medications can be administered orally on a routine outpatient basis, or via intravenous route if necessary in the emergency room.

What is AVNRT in medicine?

Atrioventricular nodal reentry tachycardia (AVNRT) is the most common type of supraventricular tachycardia. People with AVNRT have episodes of an abnormally fast heartbeat (more than 100 beats per minute) that often start and end suddenly.

What drugs block AV node?
