Atrioventricular Reentrant Tachycardia

2020
A 19-year-old female underwent EP study for symptomatic SVT. Ventricular pacing demonstrated eccentric conduction was present. Diagnosis of AVRT with left-sided accessory pathway was reached while other SVT types were excluded. Ablation was successful after mapping the mitral ring via a transseptal approach.

Atrioventricular nodal Reentrant Tachycardia with Atrioventricular Block

Journal of Interventional Cardiac Electrophysiology, 1997
Atrioventricular block (AVB) during atrioventricular nodal reentrant tachycardia (AVNRT) has been well documented, although it is not a common phenomenon. The mechanism for the initiation and resolution of AVB during AVNRT have been postulated. However, the site of AVB and its implication on the reentrant circuit in AVNRT is not clear.

Haemodynamic analysis of atrioventricular tachycardia

European Heart Journal, 1992
The aim of the study was to delineate the influence of the ventriculo-atrial interval (VAI) in tachycardia with regard to the underlying heart disease. Haemodynamic studies were performed by the conductance catheter technique during paced tachycardia with a HR of 140, 160 and 180 beat.min-1 at various VAI in 10 patients; three with coronary heart ...

Supraventricular Tachycardia and Atrioventricular Block

Cardiac Electrophysiology Clinics, 2010
The differential diagnosis for a mid- to long-RP supraventricular tachycardia include atrial tachycardia, atypical atrioventricular nodal reentrant tachycardia (AVNRT), and atrioventricular reentrant tachycardia (AVRT) utilizing a slowly conducting concealed accessory pathway. The presence of spontaneous atrioventricular block excludes AVRT.

Antiarrhythmic Treatment of Atrioventricular Tachycardias

Journal of Cardiovascular Pharmacology, 1991
Atrioventricular (AV) tachycardia includes both AV nodal reentrant tachycardia (AVNRT) and AV reentrant tachycardia (AVRT) using an accessory pathway. The treatment of the acute attack is different from the long-term treatment of both AVNRT and AVRT. Verapamil and adenosine, by prolonging the refractory period of the AV node, are highly effective in ...

Atrioventricular nodal supraventricular tachycardia

The American Journal of Cardiology, 1985
Abstract Most patients with paroxysmal supraventricular tachycardia (SVT) have atrioventricular (AV) nodal reentrant SVT using the slow AV nodal pathway for anterograde conduction and the fast pathway for retrograde conduction. Patients with dual pathways may rarely have a form of SVT in which anterograde conduction occurs over the fast pathway and ...

Atrioventricular block after reciprocating atrioventricular junctional tachycardia

The American Journal of Cardiology, 1975
Short runs of symptomatic atrioventricular (A-V) block occurred after spontaneous cessation of reciprocating A-V junctional tachycardia in a patient with right bundle branch block, normal H-V interval and sinus nodal dysfunction. These episodes were characterized by long (more than 1 sec) P-P intervals during which the A deflections were not followed ...

Atrioventricular Reentry Tachycardia

2020
Atrioventricular reentry tachycardia (AVRT) is the second most common type of paroxysmal supraventricular tachycardia and requires an accessory pathway (AP) that bypasses conduction through the atrioventricular (AV) node. The manifestation of ventricular preexcitation in sinus rhythm with paroxysmal tachycardia is called Wolff-Parkinson-White syndrome.

Atrioventricular Nodal Reentrant Tachycardia

Medical Clinics of North America, 1984
This entity represents the most common type of recurrent, regular, narrow QRS tachycardia in the absence of preexcitation syndrome. Electrophysiologic basis for the arrhythmia is reentry within the AV node resulting from dissociation between intranodal pathways.
