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 ...

ST‐Segment Elevation Following Adenosine Administration for SVT: Diagnostic Challenge in Acute Cardiac Care

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ST segment elevation following adenosine administration in the inferior leads (II, III, aVF). ABSTRACT Adenosine, used to treat paroxysmal supraventricular tachycardia, commonly causes flushing, sweating, palpitations, and hypotension. Rarely, it may induce ST‐segment elevation with chest pain, suggesting transient myocardial ischemia or coronary ...

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]

, 2000
During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.

Prevalence and Structured Approach to the Diagnoses of A on V Tachycardias

Journal of Arrhythmia, Volume 42, Issue 2, April 2026.
Schematic tachycardia circuit diagram and corresponding laddergram depicting how atrial and ventricular activations become coincident to exhibit true A on V tachycardia, contrasted with the electrophysiologic basis of pseudo A on V patterns. ABSTRACT Background “A on V” tachycardia (AoV‐T) is classically considered suggestive of atrioventricular nodal ...

Supraventricular Arrhythmias in Pulmonary Hypertension: A Comprehensive Review From Preclinical Evidence to Clinical Practice

Pulmonary Circulation, Volume 16, Issue 1, January 2026.
ABSTRACT Pulmonary Hypertension (PH) is a chronic disease that causes significant structural deterioration in the right atrium and ventricle. In the past 1–2 decades, life expectancy in patients with PH has increased due to improved awareness, diagnosis and advancements in treatment.

Zero Fluoroscopy Ablation of Arrhythmias in Patients With Congenital Heart Disease

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Zero‐fluoroscopy radiofrequency ablation using 3D electroanatomic mapping was performed in 42 patients with mild, moderate, or great complexity congenital heart disease. Acute success was 100%, with no complications and minimal recurrence over 48 months. This approach eliminates radiation exposure while maintaining safety and efficacy across select yet
