What is a Idioventricular rhythm?

As a medical professional with expertise in cardiology, I can provide you with an explanation of what an Idioventricular rhythm is. An Idioventricular rhythm is a type of cardiac rhythm that originates within the ventricles of the heart. This rhythm occurs when the normal conduction system of the heart is bypassed, and the electrical impulses that trigger the heartbeat are generated spontaneously by the ventricular cells themselves. The key characteristics of an Idioventricular rhythm include: 1. QRS Complexes: The QRS complexes on an electrocardiogram (ECG) are wide and may appear bizarre, often greater than 0.12 seconds in duration. This is because the electrical signals are not being transmitted through the normal conduction pathways but are instead spreading cell-to-cell among the ventricular cardiomyocytes. 2. Rate: The rate of an Idioventricular rhythm is typically between 20 and 40 beats per minute (bpm). If the rate exceeds 40 bpm, it is referred to as an accelerated idioventricular rhythm. It's important to note that while an Idioventricular rhythm may be a sign of an underlying heart condition, it is not always indicative of a serious problem. The clinical significance of this rhythm depends on the patient's symptoms and the context in which it occurs.

This is called Idioventricular Rhythm. Ventricular signals are transmitted cell-to-cell between cardiomyocytes and not by the conduction system, creating wide sometimes bizarre QRS complexes(> 0.12 sec). The rate is usually 20-40 bpm. If the rate is >40 bpm, it is called accelerated idioventricular rhythm.
