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. ECG features depend on the direction of conduction, which can be orthodromic or antidromic.

Sep 6, 2024 · It could be atrioventricular reentrant tachycardia (AVRT), a condition caused by an extra connection between the upper and lower chambers of your heart. Find out what causes it and how to...

Atrioventricular reentrant tachycardia (AVRT), or atrioventricular reciprocating tachycardia, is a type of heart arrhythmia with an abnormally fast rhythm (tachycardia); it is classified as a type of supraventricular tachycardia (SVT).

Feb 27, 2024 · Any chronic arrhythmia can cause tachycardia-induced cardiomyopathy, such as incessant AVRT due to a septal accessory pathway, permanent junctional reciprocating tachycardia, rapid AF, idiopathic ventricular tachycardia, and focal atrial tachycardia.

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.

Sep 13, 2024 · Atrioventricular reentrant tachycardia (AVRT) is a common variety of SVT. While it frequently produces significant symptoms and can be quite disruptive to life, AVRT today is often curable with ablation.

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. People with AVNRT have an irregularly fast heartbeat that often starts and ends suddenly. In AVNRT, the heart beats more than 100 times a minute.

Apr 28, 2022 · What causes AVNRT? Electrical signals control the rate and rhythm of your heart. They start in the sinoatrial (SA) node, a special group of muscle fibers in your heart’s upper right chamber (atrium). The SA node is your heart’s natural pacemaker.

Individuals with accessory pathways are at risk of developing atrioventricular reentrant tachycardia (AVRT). This is a rapid tachyarrhythmia in which a macroscopic re-entry circuit involves the atria, atrioventricular node, accessory pathway and the ventricles. In most cases, the re-entry is induced by a premature atrial beat.

Atrioventricular Reentry Tachycardia is a type of heart arrhythmia, or irregular heartbeat. In AVRT, extra electrical signals enter the heart’s upper chambers, or atria, by an abnormal electrical pathway. This causes multiple electrical signals, resulting in a fast heartbeat, or tachycardia.
