A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

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.

Utility of a Novel 12‐Lead ECG Criterion for Localizing Manifest Right Sided Accessory Pathways: A Derivation Study

Journal of Arrhythmia, Volume 42, Issue 2, April 2026.
Compared to previously tested ECG signs, The PR/QRS ratio had the best predictive performance of right septal versus right free wall accessory pathway locations. This simple yet powerful tool has the potential to improve patient safety, optimize ablation strategies, and ultimately lead to better outcomes for patients with accessory pathways.

A surgical resection case of myxoma arising from the posterior wall of the left atrium complicated with complete atrioventricular block

Journal of Cardiothoracic Surgery
An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near

Exploring heart rate variability as a biomarker for frailty: A narrative review

European Journal of Clinical Investigation, Volume 56, Issue 4, April 2026.
Frailty arises from progressive multisystem dysregulation, prompting interest in biomarkers that capture declining physiological reserve. This review positions heart rate variability (HRV) within this evolving biomarker landscape, outlining its physiological basis, analytical domains and relevance to clinical research.

Familial sick sinus syndrome in two siblings

The Turkish Journal of Pediatrics, 1993
Two siblings with sinus node disease are presented. The patients were severely affected and required permanent pacing. A cardiac electrophysiologic study was conducted in Case 2, which revealed an atrioventricular conduction disturbance in ...
