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.

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.

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 perinodal atrial tissue.

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

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 …

Dec 29, 2025 · 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 …

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

Jun 5, 2025 · AVNRT is a reentrant rhythm that exploits dual conduction pathways within the AV node. It initiates when conduction conditions—especially following a premature atrial beat—favor travel down …

Jul 1, 2025 · Data regarding the effects of pulsed field ablation (PFA) on atrioventricular nodal reentrant tachycardia (AVNRT) are limited. This study was undertaken to evaluate the outcomes of PFA for …
