The electrical loop causing rapid heartbeats in the AV node
In short: Understand the mechanics of atrioventricular re-entry tachycardia (AVRNT), a common heart rhythm disorder. This video breaks down how abnormal electrical pathways create a self-sustaining loop, leading to rapid heartbeats.
AVRNT is a type of supraventricular tachycardia where electrical signals travel in an abnormal circuit within or near the atrioventricular (AV) node. This re-entry mechanism causes the heart to beat rapidly and can be particularly common in young women.
The video explores the pathophysiology of these circuits, the clinical symptoms patients experience, and various intervention methods. These range from non-invasive vagal maneuvers and medications to more permanent procedures like ablation therapy.
