Drugs that block the AV node are used for rate control in narrow complex supraventricular tachyarrhythmias.
- Adenosine
- Beta-Blockers
- Calcium channel blockers (non-dihydropyridine)
- Digoxin
***”These AV nodal blocking agents must be avoided in conditions like WPW because they may facilitate conduction over the accessory pathway and increase ventricular rate paradoxically, initiating VF.”
