accelerated ventricular Escape Rhythm

AIVR is a relatively benign reperfusion arrhythmia

Suggests successful reperfusion of an occluded coronary vessel in AMI (spontaneous or s/p thrombolytics)

• Other presentations: digoxin toxicity, severe electrolyte abnormalities, post-arrest rhythms

Unlikely to cause hemodynamic instability

Suppression with antiarrhythmics can cause instability, asystole

Rhythm tends to be transient

Treatment is to simply observe!
