Electrophysiological differences of randomized deep sedation with dexmedetomidine versus propofol

open access: yesBMC Anesthesiology
Background Dexmedetomidine and propofol are common sedatives in intensive care units and for interventional procedures. Both may compromise sinus node function and atrioventricular conduction.

Surgical and Electrical Anatomy of the Inter-Nodal and Intra-Atrial Conduction System in the Heart

open access: yesJournal of Chest Surgery, 2022
An anatomical understanding of the atrial myocardium is crucial for surgeons and interventionists who treat atrial arrhythmias. We reviewed the anatomy of the inter-nodal and intra-atrial conduction systems.

Cystic tumour of the atrioventricular node: case report and literature review

open access: yesForensic Sciences Research, 2019
Cystic tumour of the atrioventricular node is the smallest tumour that can cause sudden cardiac death. This lesion arises from foregut endodermal rests which become enfolded into the heart during embryogenesis.

Atrioventricular canal defect and genetic syndromes: the unifying role of sonic hedgehog [PDF]

open access: yes, 2019
The atrioventricular canal defect (AVCD) is a congenital heart defect (CHD) frequently associated with extracardiac anomalies (75%). Previous observations from a personal series of patients with AVCD and "polydactyly syndromes" showed that the distinct ...

Effect of nitric oxide modulation on the basic and rate-dependent electrophysiological properties of AV-node in the isolated heart of rabbit: The role of adrenergic and cholinergic receptors [PDF]

open access: yes, 2010
Introduction: Recent studies showed that nitrergic system have specific modulatory effects on electrophysiological properties of atrioventricular (AV) node.

Advanced ablation strategies for management of post-surgical atrial arrhythmias. [PDF]

open access: yes, 2013
Post-surgical arrhythmias include a wide range of arrhythmias occurring late after cardiac surgery and represent a complex substrate for catheter ablation either because of extended scar and remodeling or because of limited access to the area of interest.

Radiofrequency catheter ablation of accessory pathways and modification of atrioventricular node in children and adolescents

open access: yesThe Turkish Journal of Pediatrics, 1996
Catheter ablation of an accessory pathway and atrioventricular node modification using 550 kHz radiofrequency was attempted in 23 children and adolescents between five and 19 years of age (mean = 15.7 years). Fifteen children had accessory-pathway-

Not only Van Gogh: a case of BRASH syndrome with concomitant digoxin toxicity

open access: yesJournal of Medical Case Reports
Background Bradycardia, renal failure, atrioventricular (AV) node blocking, shock, and hyperkalemia syndrome is a potentially life-threatening clinical condition characterized by bradycardia, renal failure, atrioventricular (AV) node blocking, shock, and
