Cryothermal Energy Ablation Of Cardiac Arrhythmias 2005: State Of The Art [PDF]

open access: yes, 2005
At the time of antiarrhythmic surgery, cryothermal energy application by a hand-held probe was used to complement dissections and resections and permanently abolish the arrhythmogenic substrate.

Spread of Activity Through the Atrioventricular Node [PDF]

open access: yesCirculation Research, 1960
Electrophysiologic mapping experiments on the excitation of the A-V node of isolated rabbit heart have been performed with intracellular microelectrodes. An area of tissue showing peculiar physiologic characteristics was shown to coincide, at least in part, with the histologic A-V node and His bundle.

PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

open access: yesAdvanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.

A case of typical atrioventricular nodal (AVN) reentrant tachycardia confined to the compact AV node, showing a variety of rare electrophysiological findings, including eccentric AVN echoes

open access: yesJournal of Arrhythmia, 2014
Herein, we report the case of a 49-year-old woman with typical atrioventricular nodal (AVN) reentrant tachycardia, confined to the compact atrioventricular node, showing numerous rare electrophysiological findings such as unique AVN reentrant echoes ...

Protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using extracellular field potential recordings of isolated atrioventricular-node of rabbit [PDF]

open access: yes, 2011
Introduction: Recent studies have shown acute cardioprotective effects of cyclosporine. The aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using ...

An Opto‐Bio‐Hydrodynamic Platform for Instructing Cardiac Left‐Right Asymmetry Development

open access: yesAdvanced Science, EarlyView.
By establishing mechanistic links among optically tuned ciliary dynamics, flow‐mediated signaling, and organ asymmetry, a multifunctional Opto‐Bio‐Hydrodynamic platform is developed to modulate ciliary motion with the programmable near infrared light for instructing cardiac left‐right asymmetry development in a spatiotemporally controlled manner, which

Ventricular response during lungeing exercise in horses with lone atrial fibrillation [PDF]

open access: yes, 2013
Reasons for performing the study Atrial fibrillation (AF) is the most important dysrhythmia affecting performance in horses and has been associated with incoordination, collapse and sudden death.

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Repeated misclassifications of tachycardia by an implantable cardiac defibrillator

open access: yesIndian Pacing and Electrophysiology Journal, 2020
This case describes repeated misclassifications of SVT due to AV node reentry as VT by an ICD. This case illustrates the limitations of SVT-VT discrimination algorithm.

Age-dependent dynamic electrophysiological field potential behavior of atrioventricular node during experimental AF in rabbit [PDF]

open access: yes, 2010
Introduction: Electrophysiological studies have demonstrated a relationship between aging and atrioventricular (AV) nodal conduction and refractoriness.
