What is the most common form of supraventricular tachycardia?

Atrioventricular nodal reentrant tachycardia (AVRT) is widely recognized as the most common form of supraventricular tachycardia (SVT). AVRT primarily arises from a reentrant circuit that includes the atrioventricular (AV) node, which plays a crucial role in the electrical conduction system of the heart. This condition is characterized by episodes of rapid heartbeats that can occur suddenly and often resolve spontaneously.

The frequency of AVRT is primarily due to its physiological mechanism and the specific conduction pathways involved. In many cases, it is associated with a reentrant loop that creates an electrical circuit involving both the atria and ventricles, allowing for rapid heart rates that can exceed 150 beats per minute. This makes it a prevalent form of SVT, particularly among younger individuals.

While other forms of supraventricular tachycardia, such as atrial flutter, paroxysmal atrial tachycardia, and conditions like Wolff-Parkinson-White syndrome, certainly exist and can occur with notable frequency, they do not match AVRT in terms of prevalence. Atrial flutter generally has a more distinct rhythm and often requires different management strategies. Paroxysmal atrial
