Nov 18, 2022 · Atrioventricular Nodal Reentrant Tachycardia (AVNRT) is a type of SVT and is the commonest cause of palpitations in patients with hearts exhibiting no structurally abnormality.

Oct 5, 2024 · Atrioventricular nodal reentry tachycardia (AVNRT) is a type of irregular heartbeat, also called an arrhythmia. It is the most common type of supraventricular tachycardia.

AVNRT is a type of arrhythmia that makes your heart beat much faster than normal — typically 120 to 200 beats per minute. It’s not life-threatening, but it can cause symptoms that come and go suddenly.

Dec 16, 2025 · Atrioventricular nodal reentrant tachycardia (AVNRT) is a regular supraventricular tachycardia (SVT) that results from the formation of a reentry circuit confined to the AV node and …

AVNRT occurs when a reentrant circuit forms within or just next to the atrioventricular node. The circuit usually involves two anatomical pathways: the fast pathway and the slow pathway, which are both in …

Explore AVNRT: Pathways, node function, ECG patterns, and classifications of Typical (Slow-Fast) and Atypical (Fast-Slow) AVNRT.

Learn about Atrioventricular Nodal Reentry (Reentrant) Tachycardia (AVNRT), with emphasis on ECG, clinical features, physiology, management and prognosis.

Jun 5, 2025 · AV Nodal Reentry Tachycardia (AVNRT) is frequently encountered in the emergency department and electrophysiology lab. It arises not from an ectopic focus, but from a reentrant circuit …

Feb 2, 2026 · AVNRT is a type of arrhythmia that causes a fast and regular heartbeat. Symptoms of AVNRT include palpitations, dizziness, and shortness of breath. AVNRT can sometimes be treated …
