In this lecture, we will discuss accelerated Idioventricular Rhythm. Accelerated Idioventricular Rhythm is also known as “Slow Ventricular Tachycardia”. AIVR is an increased ventricular rhythm that has at least 3 consecutive ventricular beats with a rate between 50 and 100 beats per minute.

Keep in mind that the AIVR differs from the following rhythm abnormalities.

Ventricular escape rhythm is a self-generated electrical discharge originating in the ventricles and causing their contraction. This is a protective response that occurs in the absence of impulses (e.g. during a third degree heart block when both the SA node and AV node are firing at a rate lower than that of the ventricle.) This occurs almost 2-3 seconds after an electrical impulse has failed to reach the ventricles. The heart rate is less than 40 beats per minute. Since it is a phenomena that prevents cardiac arrest from occurring, its management involves correcting the rhythm, not getting rid of it.
Ventricular tachycardia, which is a heart rate greater than 120 beats per minute.
Remember that both the ventricular escape and ventricular tachycardia are not AIVR

AIVR affects only the ventricles, and is considered an ectopic arrhythmia.

It is usually regarded as a benign, self-limiting arrhythmia, therefore, it does not require treatment.
