Intermittent Ventricular Pre‐Excitation: Clinical Features and Electrophysiological Properties

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Intermittent ventricular pre‐excitation has long been considered a low‐risk marker for sudden death. Accessory pathways (APs) with high‐risk intermittent antegrade conductive properties may exist, but this still represents a gray area in current guidelines.

Etripamil Nasal Spray for Recurrent Paroxysmal Supraventricular Tachycardia Conversion: Results From the NODE‐303 Open‐Label Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Etripamil is a fast‐acting intranasally self‐administered calcium‐channel blocker developed for termination of paroxysmal supraventricular tachycardia (PSVT). Prior studies have demonstrated safety and efficacy of etripamil for PSVT termination following an initial medically supervised test dose during sinus rhythm. NODE‐303 is an

Sex‐specific activation of SK current by isoproterenol facilitates action potential triangulation and arrhythmogenesis in rabbit ventricles [PDF]

, 2018
Sex has a large influence on cardiac electrophysiological properties. Whether sex differences exist in apamin‐sensitive small conductance Ca2+‐activated K+ (SK) current (IKAS) remains unknown.

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

Journal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

Fundamentals of System Design for Cardiac Pulsed Field Ablation: Optimization of Safety, Efficacy, and Usability

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT The goal of a cardiac pulsed field ablation (PFA) system is to provide safe, effective, and usable therapy for the treatment of cardiac arrhythmias. Achieving this goal is a complex exercise in system design, requiring optimization of catheter, waveform, and dosing. This optimization is often iterative, as myriad design factors are balanced to

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-
