Optimal cardiac function depends on proper timing of excitation and contraction in various
regions of the heart, as well as on appropriate heart rate. This is accomplished via …

After its recognition as a distinct clinical entity, Brugada syndrome is increasingly recognized
worldwide as an important cause of sudden cardiac death. Brugada syndrome exhibits …

Background—There is emerging evidence that localization and elimination of abnormal
electric activity in the epicardial right ventricular outflow tract may be beneficial in patients …

Background—Whether Brugada syndrome (BrS) depends on functional epicardial
substrates, which may be definitively eliminated by radiofrequency ablation, remains …

Background—Conduction abnormalities serve as a substrate for ventricular fibrillation (VF)
in patients with Brugada syndrome (BS). Signal-averaged electrograms can detect late …

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

Objectives: The goal of our work was to examine the relationships of atrial fibrillation (AF)
with genetic, clinical, and electrophysiological backgrounds in Brugada syndrome (BrS) …

Aims Brugada syndrome (BS) is an ion channelopathy with the risk of sudden cardiac death.
The role of programmed ventricular stimulation (PVS) in risk stratification has been …

Background—Although Brugada syndrome revolves around reduced net depolarizing force,
the electrophysiological mechanisms of its defining features (right precordial ST-segment …

Sinus node dysfunction may be either transient (reversible/physiological) due to the
involvement of the autonomic nervous system or pharmaceuticals, or chronic due to …
