Accelerated Idioventricular Rhythm (AIVR)

1. AIVR refers to a ventricular rhythm that is characterized by three or more complexes at a rate >40 beats/min and <120 beats/min. Mechanism is due to abnormal automaticity.

2. AIVR has a characteristic gradual onset and offset and more variability in cycle length. It is typically a brief, self-limiting arrhythmia.

3. AIVR can be seen in

a. Acute myocardial infarction,

b. Cocaine intoxication,

c. Acute myocarditis,

d. Digoxin intoxication,

e. Postoperative cardiac surgery.

4. In the setting of sustained AIVR, hemodynamic compromise can occur because of the loss of AV synchrony.
