BACKGROUND Catheter ablation is increasingly used to manage atrial fibrillation, but arrhythmia recurrences are common. Adenosine might identify pulmonary veins at risk of reconnection by unmasking dormant conduction, and thereby guide additional ablation to improve arrhythmia-free survival. We assessed whether adenosine-guided pulmonary vein isolation(More)
BACKGROUND Defibrillation testing by induction and termination of ventricular fibrillation is widely done at the time of implantation of implantable cardioverter defibrillators (ICDs). We aimed to compare the efficacy and safety of ICD implantation without defibrillation testing versus the standard of ICD implantation with defibrillation testing. METHODS(More)
UNLABELLED Syncope is experienced by a third of the population, and in the absence of cardiac pathology is most commonly of vasovagal (VVS) or unexplained origin (US). Psychiatric morbidity has been observed in up to 81% of patients with US but findings with VVS are contradictory. Little is known regarding the chronicity of their psychiatric morbidity. (More)
Focal point-by-point radiofrequency catheter ablation has shown considerable success in the treatment of paroxysmal atrial fibrillation. However, it is not without limitations. Recent clinical and preclinical studies have demonstrated that cryothermal ablation using a balloon catheter (Artic Front©, Medtronic CryoCath LP) provides an effective alternative(More)
This paper is dedicated to design an efficient met heuristic based on Bayesian approach to solve continuous optimization problems. The proposed approach is based on the use of different search strategies (crossover and mutation) and then selects the best strategy from those possible ones based on the Bayes theorem. The obtained results were compared to(More)
BACKGROUND It is well recognized that right ventricular apical pacing can have deleterious effects on ventricular function. We performed a head-to-head comparison of the SafeR pacing algorithm versus DDD pacing with a long atrioventricular delay in a heterogeneous population of patients with dual-chamber pacemakers. METHODS AND RESULTS In a multicenter(More)
Cardiac resynchronization therapy (CRT) aims at improving systolic function in patients with heart failure. We investigated the use of body surface potential mapping (BSPM) in the understanding of the activation sequence in the myocardium during biventricular (BiV) pacing. We acquired BSPM recordings in 29 patients with an implanted BiV device during normal(More)
