Idioventricular Rhythm is a cardiac rhythm where the electrical impulses originate within the ventricles, typically at a rate slower than the normal sinus rhythm. It occurs when the normal pacemaker sites in the atria or the atrioventricular (AV) junction fail to generate impulses or are blocked, and the ventricles take over as the primary pacemaker.
Heart Rate: 20 to 40 beats per minute
Rhythm: Regular
P wave: Absent
PR Interval:Not applicable
QRS:greater than 0.12 seconds
Idioventricular Rhythm is diagnosed through an electrocardiogram (ECG) or continuous cardiac monitoring. Characteristic features include a regular rhythm with wide QRS complexes and the absence of a preceding P wave or a dissociated P wave morphology.
Treatment may involve managing any reversible factors contributing to the idioventricular rhythm. Temporary Pacing: in some cases, temporary pacing may be initiated to stabilize the heart rate while addressing the underlying issues. Permanent Pacing:If idioventricular rhythm persists and causes symptoms or complications, permanent pacing with the implantation of a pacemaker may be considered. The pacemaker ensures a regular and appropriate heart rate.
