Background Early repolarization is a common electrocardiographic finding that is generally
considered to be benign. Its potential to cause cardiac arrhythmias has been hypothesized …

Pulsed field ablation (PFA) is an emerging technology for the treatment of atrial fibrillation (AF),
for which pre-clinical and early-stage clinical data are suggestive of some degree of …

Aims Left atrial appendage closure is a non-pharmacological alternative for stroke prevention
in high-risk patients with non-valvular atrial fibrillation. The objective of the multicentre …

Background Single-chamber ventricular leadless pacemakers do not support atrial pacing
or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system …

Background Sleep apnea (SA) is associated with cardiovascular diseases and is highly
prevalent in patients with pacemakers (PMs). Objective To validate a transthoracic impedance …

Background— Brugada syndrome is an arrhythmogenic disease characterized by an increased
risk of sudden cardiac death (SCD) by ventricular fibrillation. At present, an implantable …

Objectives : Our purpose was to evaluate the efficacy of antiarrhythmic drugs (AADs) in
recurrent ventricular fibrillation (VF) associated with inferolateral early repolarization pattern on …

Background : Transcatheter left atrial appendage (LAA) occlusion is an alternative strategy
for stroke prevention in patients with atrial fibrillation (AF). Objectives : This study sought to …

Background— Cardiovascular diseases leading to pacemaker implantations are suspected
of being associated with a high rate of undiagnosed sleep apnea syndrome (SAS). We …

A thrombin-like serine protease, jararassin-I, was isolated from the venom of Bothrops jararaca.
The protein was obtained in high yield and purity by a single chromatographic step using …
