The relationship between Obstructive sleep apnea (OSA) and Atrialfibrillation (AF) is well established as existing literature has concluded that sleep apnea creates a unique, complex, and dynamic substrate for AF, with various pathophysiological mechanisms.
Previous studies evaluated its value in predicting atrialfibrillation (AF) occurrence. Additionally, thirty-eight patients with AF who underwent radiofrequency catheter ablation were enrolled and followed-up for 3–36 months. IntroductionCorrected QT interval (QTc) is a ventricular repolarization marker on electrocardiography.
Pulsed field ablation (PFA) for paroxysmal atrialfibrillation (AF) has been gaining worldwide acceptance due to its efficacy and safety. A variable loop circular catheter (VLCC, VARIPULSE, Biosense Webster, Inc.)
This systematic review and meta-analysis investigates the efficacy of catheter ablation compared with rate or rhythm control among patients with atrialfibrillation and heart failure.
Data on long-term effects of catheter ablation versus antiarrhythmic drugs (AAD) on health-related quality of life (HRQoL) and atrialfibrillation (AF) burden are limited.
(MedPage Today) -- For patients undergoing catheter ablation for atrialfibrillation (Afib), there was no signal that a brief course of colchicine reduced atrial arrhythmia recurrence or improved clinical outcomes when taken for 10 days starting.
Research conducted across 12 hospitals in China has discovered that combining linear ablation with ethanol infusion via the vein of Marshall (EIVOM) alongside pulmonary vein isolation (PVI) significantly improves sinus rhythm maintenance in patients suffering from persistent atrialfibrillation.
