ECG Presentation Typically, AVNRT is a narrow-complex tachycardia, ie, QRS duration <120 ms, unless aberrant conduction, which is usually of the right bundle-branch type, or a previous conduction defect exists. Tachycardia-related ST depression and RR-interval variation may be seen.
Differentiating features of AVNRT and AVRT Download Table
Atrioventricular nodal reentrant tachycardia (AVNRT) is an arrhythmia frequently encountered in an otherwise healthy patient population. Catheter ablation should be considered as an initial treatment choice in symptomatic patients with AVNRT, given the high success rate and low risk for complications.
AV nodal reentrant tachycardia Diagnosis and Treatment
Atrioventricular nodal reentry tachycardia (AVNRT) is the most common type of supraventricular tachycardia. People with AVNRT have episodes of an irregularly fast heartbeat (more than 100 beats per minute) that often start and end suddenly.
PPT Arrhythmias The Good, the Bad and the Ugly PowerPoint Presentation ID6582309
The two main forms of tachyarrhythmias that occur due to accessory pathways are discussed separately — see atrioventricular re-entry tachycardia (AVRT) and atrial fibrillation/flutter in pre-excitation. Overview of Wolff-Parkinson-White (WPW) Syndrome
Supraventricular Tachycardia Types Cardiology Outlines
When AVNRT and AVRT are compared, symptoms appear to significantly differ. Individuals with AVNRT more frequently describe sensations of "neck pounding" that may be related to pulsatile reversed flow when the atria contract against a closed tricuspid valve.

The atrioventricular node and bundle of His are normally the only communication between the atria and the ventricles. The atrial impulse must pass through the atrioventricular node, which delays the impulse due to its slow conduction, before the impulse may reach the ventricles.
Avrt and avnrt
Atrioventricular nodal reentrant tachycardia (AVNRT) is a common tachyarrhythmia occurring in all age groups, from children to elderly. AVNRT is common also among individuals who are healthy. This arrhythmia typically starts and terminates very abruptly.
Differentiating Atrioventricular Reentry Tachycardia and Atrioventricular Node Reentry
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. Because of its abrupt onset and termination, AVNRT is categorized as a paroxysmal SVT (PSVT).
SVT (AVRT, AVNRT) For DO, MD, NP, PA [Part 3] YouTube
Current maneuvers for differentiation of atrioventricular node reentry tachycardia (AVNRT) and atrioventricular reentry tachycardia (AVRT) lack sensitivity and specificity for AVRT circuits located away from the site of pacing.

Atrioventricular Nodal Reentrant Tachycardia is a type of supraventricular tachycardia (ie it originates above the level of the Bundle of His) and is the commonest cause of palpitations in patients with hearts exhibiting no structurally abnormality. Clinical Features of AVNRT
AVNRT VS AVRT How to differentiate AVNRT from AVRT on ECG definition, ECG findings and
AVNRT and AVRT - The Student Physiologist AVNRT and AVRT Arrhythmias caused by a surplus conduction circuit between atrial and ventricular anatomy. They cause the normal electrical circuit to allow an impulse to repeatedly travel around the normal AV node and this new connection. AVNRT Atrioventricular Nodal Re-entrant Tachycardia
Differentiating Atrioventricular Reentry Tachycardia and Atrioventricular Node Reentry
Atrioventricular Nodal Re-entrant Tachycardia is another type of re-entrant tachycardia like AVRT, but it has its differences. So people call this AVNRT for short. Remember, this is very different than AVRT. It's called AVNRT, N is for Nodal, because the abnormal loop of electricity, or that abnormal re-entrant circuit, directly involves the AV.

May 20, 2022 Home ECG Library Atrioventricular Re-entry Tachycardia (AVRT) is a form of paroxysmal supraventricular tachycardia that occurs in patients with accessory pathways, usually due to formation of a re-entry circuit between the AV node and accessory pathway.
Supraventricular Tachycardias Paroxysmal SVT A broad term which includes AVNRT, AVRT and a few
Paroxysmal supraventricular tachycardia is a term that refers to SVTs with abrupt onset and termination. AVNRT is a reentrant tachycardia that utilizes the AV node and perinodal tissues to sustain tachycardia. AVRT is a macro-reentrant tachycardia that utilizes an accessory pathway to create a circuit involving the ventricle.
Differentiation between AVNRT and AVRT_advanced lecture
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common form of regular supraventricular tachycardia and is routinely treated with catheter ablation (CA). AVNRT most commonly affects young and middle-aged otherwise healthy adults; females are more frequently affected than males.[1][2]
