Radiofrequency catheter ablation reduces the severity of anxiety in patients with atrioventricular nodal reentry tachycardia, regardless of age, sex, tachycardia type, and laboratory findings

Medicine Science
Assess pre and postinterventional anxiety levels in radiofrequency catheter ablation recipients (RFCA) for atrioventricular nodal reentry tachycardia (AVNRT) and investigate whether changes are associated with demographic and clinical characteristics and

AV Nodal Reentrant Tachycardia in a Patient with Persistent Left Superior Vena Cava: Distinction between AV Nodal Versus Atrial Reentry

Journal of Arrhythmia, 2010
A 75-year-old male presented with palpitation on exertion. He suffered from frequent tachycardia attacks. His 12-leads electrocardiogram showed irregular cycle lengths (400–550 ms) of tachycardia with occasional 2:1 atrioventricular conduction (thus AV ...

Interesting response to ventricular overdrive pacing during regular narrow QRS tachycardia. What is the mechanism?

Indian Pacing and Electrophysiology Journal, 2020
33 year old gentleman has undergone an electrophysiology study for recurrent paroxysmal palpitation. During one of the episodes of palpitation a regular narrow QRS tachycardia was documented which has terminated with intravenous adenosine.

Dynamic age-related changes of extracellular field potential of isolated AV-node of rabbit [PDF]

, 2011
Introduction: Developmental changes in atrioventricular nodal conduction time and refractoriness have been shown in several studies. Prevalence of atrioventricular nodal reentrant tachycardia (AVNRT) is clearly age-dependent.

Electrophysiological properties of myocytes isolated from the mouse atrioventricular node:L-type ICa, IKr, If, and Na-Ca exchange [PDF]

, 2015
The atrioventricular node (AVN) is a key component of the cardiac pacemaker-conduction system. This study investigated the electrophysiology of cells isolated from the AVN region of adult mouse hearts, and compared murine ionic current magnitude with ...

ICD discrimination of SVT versus VT with 1:1 V-A conduction: A review of the literature

Indian Pacing and Electrophysiology Journal, 2015
Inappropriate ICD shocks are associated with increased mortality. They also impair patients' quality of life, increase hospitalizations, and raise health-care costs. Nearly 80% of inappropriate ICD shocks are caused by supraventricular tachycardia.

Differential responses of the septal ventricle and the atrial signals during ongoing entrainment: a method to differentiate orthodromic reciprocating tachycardia using septal accessory pathways from atypical atrioventricular nodal reentry [PDF]

, 2015
[EN]Differential diagnosis between tachycardia mediated by septal accessory pathways (AP) and atypical atrioventricular nodal reentry can be challenging. We hypothesized that an immediate versus delayed pace-related advancement of the atrial electrogram,

Effects of Acute Autonomic Modulation on Atrial Conduction Delay and Local Electrograms Duration in Paroxysmal Atrial Fibrillation [PDF]

, 2011
Slowed atrial conduction may contribute to reentry circuits and vulnerability for atrial fibrillation (AF). The autonomic nervous system (ANS) has modulating effects on electrophysiological properties.
