How is accelerated idioventricular rhythm (AIVR) treated?
Treatment for accelerated idioventricular rhythm (AIVR) does not change the prognosis. The most important therapy for patients with AIVR is to treat the underlying etiology. AIVR is usually hemodynamically tolerated and self-limited; thus, it rarely requires treatment. Occasionally, patients may not tolerate AIVR due to loss of atrial-ventricular synchrony, relative rapid ventricular rate, or ventricular tachycardia or ventricular fibrillation degenerated from AIVR (extremely rare). Under these situations, atropine can be used to increase the underlying sinus rate to inhibit AIVR.
@bubun Patients with AIVR should be treated mainly for its underlying causes, such as digoxin toxicity, myocardial ischemia, and structure heart diseases. Beta-blockers are often used in patients with myocardial ischemia-reperfusion and cardiomyopathy. Transfer to advanced care facility depends on associated conditions.
