Medication Summary

Atropine 0.25-1 mg is sometimes used to accelerate underlying sinus rate to inhibit accelerated idioventricular rhythm (AIVR).

Isoproterenol, verapamil, and antiarrhythmic drugs such as lidocaine and amiodarone are rarely used for AIVR.



Class Summary

The goal is to accelerate sinus rate or to improve AV conduction in atrial fibrillation to inhibit AIVR.

Atropine IV/IM (Atropisol)

Used to increase heart rate through vagolytic effects, causing an increase in cardiac output (secondary, and generally not a factor in suppressing the AIVR).
