What is a characteristic feature of Idioventricular rhythms?

The characteristic feature of Idioventricular rhythms is a rate of 20-50 beats per minute. This rhythm arises from the ventricles when the pacemaker activity from higher up in the conduction system (such as the atria or AV node) fails. As a result, the ventricles initiate their own electrical impulse, which usually propagates at a slower rate than normal, leading to the identified range of 20-50 beats per minute. Understanding this rate is crucial for recognizing and interpreting Idioventricular rhythms in clinical practice.
