2:1 Atrioventricular Block During Atrioventricular Node Reentrant Tachycardia

Journal of the American College of Cardiology, 1996
The purpose of this study was to determine the incidence and to clarify the mechanism of 2:1 atrioventricular (AV) block during AV node reentrant tachycardia induced in the electrophysiology laboratory.In patients with 2:1 AV block during AV node reentrant tachycardia, the absence of a His bundle potential in the blocked beats has been considered ...

New‐Onset Device‐Detected Atrial Fibrillation in Patients With Atrial Floating Dipole Implantable Cardioverter‐Defibrillators: A Propensity Score‐Matched Comparison With Conventional Dual‐Chamber Systems

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Device‐detected subclinical atrial fibrillation (DDAF) is a significant risk factor for major cardiovascular events, especially in implantable cardioverter‐defibrillator (ICD) recipients. The DX ICD, which utilizes a single ventricular lead with a floating atrial dipole, has demonstrated superior performance in diagnosing DDAF ...

Radiofrequency Catheter Ablation for Atrioventricular Node Reentry Tachycardia with Multiple Slow Atrioventricular Node Pathways.

Japanese Circulation Journal, 1995
Catheter ablation was attempted in 2 patients with atrioventricular node reentry tachycardia which showed fast, intermediate and slow anterograde atrioventricular node pathways. Radiofrequency currents were applied within a restricted area of the tricuspid annulus between the His bundle and the ostium of the coronary sinus where presumed slow pathway ...

Clinical Significance and Management of Atrioventricular Block Associated With Bradycardic/Antiarrhythmic Drug Therapy: Drug‐Induced or Drug‐Revealed?

Journal of Cardiovascular Electrophysiology, EarlyView.
Schematic representation of the management pathway in drug‐related advanced atrioventricular block. ABSTRACT The development of advanced atrioventricular block (AVB) in patients on bradycardic and/or antiarrhythmic therapy (drug‐related AVB) represents a clinical challenge, raising the question of whether the AVB is directly caused by these agents ...

Dual network structure of the AV node [PDF]

arXiv
Biological systems, particularly the brain, are frequently analyzed as networks, conveying mechanistic insights into their function and pathophysiology. This is the first study of a functional network of cardiac tissue. We use calcium imaging to obtain two functional networks in a subsidiary but essential pacemaker of the heart, the atrioventricular ...

Characterization of Driver Nodes of Anti-Stable Networks [PDF]

arXiv, 2014
A controllable network can be driven from any initial state to any desired state using driver nodes. A set of driver nodes to control a network is not unique. It is important to characterize these driver nodes and select the right driver nodes. The work discusses theory and algorithms to select driver node such that largest region of attraction can be ...

Mesothelioma in the Atrioventricular Node. Case Report.

Japanese Heart Journal, 1994
A patient with complete atrioventricular block and an implanted permanent pacemaker died of colon cancer at the age of 64 years. At autopsy, a cardiac tumor in the region of the atrioventricular node (mesothelioma of the atrioventricular node) was found. The origin of this type of tumor is controversial.

Efficacy and safety of etrasimod in alopecia areata: A multicentre, randomized, double‐blind, placebo‐controlled, Phase 2 study

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Patients with alopecia areata received etrasimod 2 mg, 3 mg or placebo oncedaily for 24 weeks, followed by a 28‐week open‐label extension period. Overall, etrasimod 2 mg and 3 mg were safe and well tolerated in patients; their efficacy was numerically higher than placebo and appeared to be dose dependent.

Repeated misclassifications of tachycardia by an implantable cardiac defibrillator

Indian 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.
