Global distribution of atrial ectopic foci triggering recurrence of atrial tachyarrhythmia after electrical cardioversion of long-standing atrial fibrillation: a bi-atrial basket mapping study.
OBJECTIVES The objective of this study was to assess the spatial distribution of atrial ectopic foci potentially triggering recurrent atrial tachyarrhythmias after electrical cardioversion of long-standing atrial fibrillation (AF). BACKGROUND It remains unknown whether targeted ablation of atrial ectopic foci concentrated in the pulmonary veins is feasible in patients with long-standin
متن کاملReversal of atrial electrical remodeling following cardioversion of long-standing atrial fibrillation in man.
BACKGROUND In animal studies, atrial fibrillation has been shown to shorten the atrial refractory period and impair its rate adaptation. However, little is known about the effects of chronic atrial fibrillation on atrial electrophysiology and its recovery course in humans. METHODS AND RESULTS Nineteen patients, mean age 64 +/- 14 years, with chronic atrial fibrillation of more than six months...
متن کاملReversal atrial electrical remodeling following cardioversion of long-standing lone atrial fibrillation.
BACKGROUND Atrial fibrillation (AF) itself promotes electrophysiological changes, termed 'electrical remodeling', facilitating its recurrence and maintenance. There is evidence that the remodeling process is reversible after restoration of the sinus rhythm (SR). However, the timing for the recovery of electrophysiological properties is still undefined. OBJECTIVE The aim of this study was to a...
متن کاملAtrial Fibrillation Cycle Length and Atrial Size in Horses with and without Recurrence of Atrial Fibrillation after Electrical Cardioversion
BACKGROUND Atrial fibrillation (AF) cycle length (CL) and atrial size have been used in humans to characterize electrical and structural remodeling to predict outcome of cardioversion of AF and risk for AF recurrence (rAF). HYPOTHESIS Atrial fibrillation cycle length can be determined in horses with AF, and AFCL and atrial size are related to risk for rAF. ANIMALS Eighteen horses with natur...
متن کاملNoninvasive Predictors of Atrial Fibrillation Early Recurrence After Electrical Cardioversion and their Link to Atrial Remodeling
Several clinical factors have been studied to predict atrial fibrillation (AF) recurrence after electrical cardioversion (ECV) with limited predictive value. In this work, several time-frequency parameters from the fibrillatory (f) waves characterization were studied to improve ECV outcome prediction at mid follow-up. By analyzing ECV outcome one month after the procedure of 63 persistent AF pa...
