| Accelerated idioventricular rhythm |
|
Accelerated idioventricular rhythm (AIVR) at a rate of 55/min presumably originating from the left ventricle (LV). Note the typical QRS morphology in lead V1 characteristic of ventricular ectopy from the LV. Monophasic R-wave with smooth upstroke and notching on the downstroke (i.e., the so-called taller left peak or "rabbit-ear".)

Accelerated idioventricular rhythm is ventricular rhythm with a rate of between 40 and 120 beats per minute. Idioventricular means "“relating to or affecting the cardiac ventricle alone“ and refers to any ectopic ventricular arrythmia.[1] Accelerated idioventricular arrhythmias are distinguished from ventricular rhythms with rates less than 40 (ventricular escape) and those faster than 120 (ventricular tachycardia).[2] Though some other references limit to between 60 and 100 beats per minute.[3] It is also referred to as AIVR and "slow ventricular tachycardia."
It can be present at birth.[4] However it is more commonly associated with reperfusion after myocardial injury.[2]
Pathophysiology
In normal hearts the sinoatrial node in the atria is the first area to depolarize and generates the action potential that leads to depolarization of the rest of the myocardium. This suppresses the intrinsic depolarization of the other parts of the heart.
The accelerated idioventricular rhythm occurs when depolarization rate of a normally suppressed focus increases to above that of the "higher order" focuses (the sinoatrial node and the atrioventricular node). This most commonly occurs in the setting of a sinus bradycardia.[5]
Accelerated idioventricular rhythm is also the most common reperfusion arrhythmia in humans. However, ventricular tachycardia and ventricular fibrillation remain the most important causes of sudden death following spontaneous restoration of antegrade flow.[6] Prior to the modern practice of percutaneous coronary intervention for acute coronary syndrome, pharmacologic thrombolysis was more common and accelerated idioventricular rhythms were used as a sign of successful reperfusion.[7] It is considered a benign arrythmia that does not require intervention, though through AV dyssynchrony can cause hemodynamic instability which can be treated through overdrive pacing or atropine.[2]
Appearance
AIVR appears similar to ventricular tachycardia with wide QRS complexes (QRS >120) and a regular rhythm. It can most easily be distinguished from VT in that the rate is less than 120 and usually less than 100 bpm. There may or may not be AV dissociation depending on whether it is due to ventricular escape or AV block.[8]

- Accelerated idioventricular rhythm associated with propranolol treatment in a child.
- Ozdemir O, Ceylan Y, Koksoy AY, Aydin H, Gultekin A, Andiran N.AbstractAccelerated idioventricular rhythm (AIVR) is a ventricular arrhythmia most commonly seen in adults with underlying cardiac disease. It is important to establish the diagnosis when it occurs to differentiate this benign phenomenon from dangerous ventricular tachycardia. We present the case of a healthy child who developed episodes of AIVR associated with propranolol treatment. Her 24-hour electrocardiography recording showed AIVR with difference between sinus and ventricular beats. The arrhythmia resolved with the discontinuation of propranolol, and eventually the case was in sinus rhythm. This patient is the first case of AIVR associated with propranolol treatment in the literature.
