2024年10月5日 · Supraventricular tachycardia (SVT) is an irregularly fast or erratic heartbeat. It occurs when faulty electrical signaling in the heart set off a series of early beats in the upper chambers of the heart. Most people with atrioventricular nodal …

2024年10月8日 · Paroxysmal SVT (pSVT) describes an SVT with abrupt onset and offset – characteristically seen with re-entrant tachycardias involving the AV node such as AVNRT or atrioventricular re-entry tachycardia (AVRT)

Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common kind of supraventricular tachycardia (SVT) due to an extra electrical pathway. SVT is a heart condition that makes the heart suddenly beat much faster than normal.

AV nodal reentrant tachycardia, AVNRT, is the most common cause of supraventricular tachycardia (SVT). It is more common in women than in men and presents in all age groups. Patients with AVNRT have at least two pathways of tissue in their AV node that allows for an abnormal electrical circuit to perpetuate within their AV node.

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 …

AV-nodal reentrant tachycardia (AVNRT) is a type of abnormal fast heart rhythm. It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His .

2022年11月18日 · 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.

2010年8月24日 · Atrioventricular nodal reentrant tachycardia (AVNRT) represents the most common regular supraventricular arrhythmia in humans. 1 The precise anatomic site and nature of the pathways involved have not yet been established, and several attempts to provide a reasonable hypothesis based on anatomic or anisotropic models have been made. 2 There has ...

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.

2015年11月1日 · Although atrial flutter, atrial fibrillation, and multi-focal atrial tachycardia also arise from this area, in practice, SVT refers to atrioventricular nodal reentrant tachycardia (AVNRT ...
