Anteroposterior Diameter of the Left Atrium Determines the Occurrence of Left Atrial Tachycardia in Non-paroxysmal Atrial Fibrillation Patients after Catheter Ablation

Majalah Kardiologi Indonesia
Objectives:             The relationship between left atrial (LA) size and atrial fibrillation (AF) is well-established. However, the specifics of LA regional remodeling and its connection to left atrial tachycardia (LA-AT) post-ablation in patients ...

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Susceptibility to Paroxysmal Atrial Fibrillation: A Study using Sinus Rhythm P Wave Parameters [PDF]

, 2010
International audienceEarly recognition of patients at high risk for atrial fibrillation may help to minimize potential health risks. The detection of susceptibility to develop atrial fibrillation is thus a real clinical challenge.

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Biomarkers in paroxysmal atrial fibrillation

Heart - Lung (Varna), 2011
През последните десетилетия заболеваемостта от предсърдномъждене(ПМ) сеувеличизначително, поради редица причини като застаряване на населението, подобрен терапевтичен подход и повишена преживяемост на пациентите със сърдечно-съдови заболявания. ПМ се асоциира с по-голям брой хоспитализации, влошено качество на живот и повишена смъртност.

Myocardial toxicity in two dogs with natural exposure to ractopamine

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract Two dogs that lived in a farm setting were presented to the Texas A&M University Veterinary Medical Teaching Hospital's Emergency Service exhibiting muscle tremors and ventricular arrhythmias following ingestion of ractopamine, a ß‐2 agonist feed‐additive used in beef cattle, pigs and turkeys intended for slaughter to increase muscle mass. The

A rare case of an unexpected trigger of paroxysmal atrial fibrillation in the right atrial appendage diverticulum

BMC Cardiovascular Disorders
Introduction We described a rare case of an adolescent girl with paroxysmal atrial fibrillation originating from the right atrial appendage diverticulum and successfully converted to sinus rhythm after surgical intervention.

Possible Deslanoside‐Induced Left Posterior Fascicular Ventricular Tachycardia: A Case Report

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
A 73‐year‐old man with paroxysmal AF and no structural heart disease who developed left posterior fascicular ventricular tachycardia (LPFVT) shortly after intravenous Deslanoside administration for rate control. Highlights: cardiac glycosides, though effective for rate control, may occasionally precipitate Purkinje‐related ventricular tachycardia ...

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 ...
