Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

Pacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

3D/2D Registration of Mapping Catheter Images for Arrhythmia Interventional Assistance

, 2009
Radiofrequency (RF) catheter ablation has transformed treatment for tachyarrhythmias and has become first-line therapy for some tachycardias. The precise localization of the arrhythmogenic site and the positioning of the RF catheter over that site are ...

Carbohydrate intake of 10 g/kg body mass rapidly replenishes liver, but not muscle glycogen contents, during 12 h of post‐exercise recovery in well‐trained cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Exhaustive cycling exercise substantially reduces liver and muscle glycogen stores. During 12 h of post‐exercise recovery without carbohydrate intake, glycogen stores remain depleted. In contrast, when carbohydrate is consumed at 10 g/kg body mass (BM), provided during the first 6 h as sucrose beverages (1.2 g/kg BM/h), liver ...

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

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

The 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-

Heart–Lung Interactions in Pulmonary Hypertension due to Heart Failure With Preserved Ejection Fraction

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review considers heart–lung interactions in pulmonary hypertension due to heart failure with preserved ejection fraction across scales, including organ, tissue, and cell scales. Key knowledge gaps in preclinical disease models, tools for clinical phenotyping, and underlying biological mechanisms are identified for future studies.

Idiopathic Fascicular Ventricular Tachycardia [PDF]

, 2004
Idiopathic fascicular ventricular tachycardia is an important cardiac arrhythmia with specific electrocardiographic features and therapeutic options. It is characterized by relatively narrow QRS complex and right bundle branch block pattern. The QRS axis

Suspected Cardioembolic Stroke Linked to Left Atrial Stunning After Pulsed Field Ablation for Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
After pulsed field ablation with pulmonary vein and posterior wall isolation, a patient developed ischemic stroke due to left carotid artery occlusion. Pathology of the retrieved thrombus revealed an acute red thrombus, suggesting left atrial stunning–induced thrombus formation.

Idiopathic Epicardial Ventricular Arrhythmias: Diagnosis and Ablation Technique from the Aortic Sinus of Valsalva [PDF]

, 2005
Idiopathic outflow tract arrhythmias (ventricular tachycardias or symptomatic premature ventricular contractions; OT-VT/PVCs) can originate from the left ventricular (LV) epicardium (Epi-VT/PVCs), and radiofrequency (RF) energy applications from the ...
