Cx43 and Dual-Pathway Electrophysiology of the Atrioventricular Node and Atrioventricular Nodal Reentry [PDF]
Circulation Research, 2003 Fluorescent imaging has revealed that posterior nodal extensions provide the anatomical substrate for the dual-pathway electrophysiology of the atrioventricular (AV) node during normal conduction and reentry. The reentry can be intranodal, or as well as the posterior nodal extensions, it can involve an endocardial layer of atrial/atrial-nodal (A/AN ...

Prevention of Atrioventricular Block During Radiofrequency Ablation by Pace Mapping of Koch’s Triangle [PDF]
Journal of Tehran University Heart Center, 2008 Background: Complete atrioventricular block (AV block) is a serious complication of slow pathway ablation therapy in the treatment of atrioventricular nodal re-entrant tachycardia (AVNRT).

Ionic basis of a differential effect of adenosine on refractoriness in rabbit AV nodal and atrial isolated myocytes [PDF]
, 1999 Methods: The whole cell patch clamp technique was used to record action potentials and ion currents in AV nodal and left atrial myocytes isolated enzymatically from rabbit hearts.

Radiofrequency catheter ablation in infants and children
SA Heart Journal, 2017 Background: Diagnosis and treatment of paediatric arrhythmias remain challenging. Antiarrhythmic - drugs beta-blockers, class Ic and class III drugs, were the only treatment available for many years. Radiofrequency catheter ablation (RFCA) was introduced

Research in Cardiovascular Medicine, 2016 Background: Ablation will efficiently lead to sinus rhythm preservation, which consequently improves left ventricular function; however, the strain rate and its indices as functional systolic factors of the left ventricle have not been studied ...

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]
, 2000 During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.

Long‐term follow‐up in preschool children after radiofrequency catheter ablation of arrhythmias
Journal of Arrhythmia, 2023 Background Radiofrequency ablation (RFA) is the standard method of treatment for tachyarrhythmias in school children, and it leads to complete recovery in children without structural heart disease. However, RFA in young children is limited by the risk of

Long-term outcomes after catheter-ablation of atrioventricular nodal reentrant tachycardia: A ten-year follow-up [PDF]
Vojnosanitetski Pregled, 2020 Background/Aim. Atrioventricular nodal (AV) reentry tachycardia (AVNRT) is the most common form of supraventricular tachycardia. Treatment of choice is a catheter-ablation of the slow pathway of the AV node.
