Multiple Arrhythmogenic Substrate for Tachycardia in a Patient with Frequent Palpitations [PDF]

, 2005
We report a 26-year-old woman with frequent episodes of palpitation and dizziness. Resting electrocardiography showed no evidence of ventricular preexcitation.

Oral flecainide is effective in management of refractory tachycardia in infants

Indian Heart Journal, 2013
Background: Propranolol and digoxin have been used as first line drugs for treatment of supraventricular tachycardia (SVT) in infants. Flecainide and other drugs have been effective as a second line treatment for controlling refractory SVT.

Electrophysiologic and antiarrhythmic effects of intravenous bisoprolol in atrioventricular nodal reentry tachycardia [PDF]

, 1996
Beta-blockade may be useful in the termination and prevention of atrioventricular nodal reentry tachycardia (AVNRT), An electrophysiologic study was performed in 9 patients (4 men and 5 women; mean +/- SD age, 56 +/- 16 years) with documented AVNRT ...

Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia: Success Rates and Complications during 14 Years of Experience [PDF]

Journal of Tehran University Heart Center, 2010
Background: Radiofrequency catheter ablation (RFCA) has been introduced as the treatment of choice for supraventricular tachycardia. The aim of this study was to evaluate the success rate as well as procedural and in-hospital complications of RFCA for ...

A jump in the atrioventricular conduction curve is not caused by a switch from fast pathway to slow pathway conduction

Frontiers in Physiology
Background: A jump in the atrioventricular (AV) conduction curve is the current clinical criterion of dual-pathway electrophysiology. However, the assumption that a jump indicates a switch from fast pathway (FP) to slow pathway (SP) conduction remains ...

Orthodromic Atrioventricular Reentry Bradycardia and Tachycardia Caused by an Accessory Pathway in Horses

Journal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Accessory pathways (APs) are muscular bundles directly connecting the atria and ventricles, bypassing the atrioventricular (AV) node‐His‐Purkinje system. Anterograde conduction along the AP results in ventricular preexcitation. A retrograde conducting AP allows ventriculo‐atrial (VA) conduction, creating a reentry circuit that ...

Cryosurgical ablation of atrioventricular nodal reentry: histologic localization of the proximal common pathway.

, 1988

Sex-related differences in patients undergoing radiofrequency ablation of atrioventricular nodal reentrant tachycardia [PDF]

, 2020
Background: Atrioventricular nodal reentry tachycardia (AVNRT) is the most common paroxysmal supraventricular tachycardia. The relatively ineffective antiarrhythmic drugs and the predominant young age makes the catheter ablation the therapy of choice in ...

Assessment of the influence of radiofrequency catheter ablation of the slow pathway of the atrioventricular node on cardiac function in patients with atrioventricular nodal reentrant tachycardia: a speckle tracking echocardiography study

Türk Kardiyoloji Derneği Arşivi, 2014
Objectives: Typical atrioventricular nodal reentrant tachycardia (AVNRT) can be cured with slow pathway ablation. This study was designed to assess the alterations in atrial and ventricular functioning using speckle tracking echocardiography in ...

The Upper Common Pathway in Atrioventricular Nodal Reentrant Tachycardia: A Comprehensive Review of Evidence and Current Perspectives

Reviews in Cardiovascular Medicine
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common form of paroxysmal supraventricular tachycardia, and its diagnostic and therapeutic approaches have been well-established.
