As a medical professional with a background in cardiology, I can explain the term "Idioventricular."
Idioventricular rhythm, also known as **accelerated idioventricular rhythm (AIVR)**, is a type of abnormal heart rhythm that originates in the ventricles of the heart. This rhythm is characterized by a slower than normal heart rate, typically between 60 and 100 beats per minute. It is called "idioventricular" because it occurs due to the ventricles' own pacemaker cells, rather than being initiated by the heart's normal pacemaker, the sinoatrial (SA) node.
In some cases, AIVR can be a normal response to certain conditions, such as a heart attack or the use of certain medications. However, it can also be a sign of an underlying heart condition that requires medical attention.
