In 1992, Brugada and Brugada first described a new entity, which became known as Brugada syndrome, that is associated with a high risk of ventricular arrhythmias and sudden cardiac death in patients without structural heart disease. This syndrome is characterized by a distinct electrocardiographic phenotype, type 1 Brugada pattern, consisting of a coved ST-segment elevation (≥0.2 mV) followed by a negative T wave in more than one right precordial lead. This pattern is dynamic, and can be spontaneous or concealed, but is unmasked under certain circumstances, like febrile states. The authors report a case in which the diagnosis of Brugada syndrome was made in the course of etiologic investigation of recurrent syncope in a febrile state.

Background: The ionic mechanism underlying Brugada syndrome (BrS) arises from an imbalance in transient outward current flow between the epicardium and endocardium. Previous studies report that artemisinin, originally derived from a Chinese herb for antimalarial use, inhibits the Ito current in canines. In a prior study, we showed the antiarrhythmic effects of artemisinin in BrS wedge preparation models.

Introduction: Brugada Syndrome (BrS) is an inherited arrhythmia syndrome characterised by ST-segment elevation in the right precordial ECG leads and is associated with an increased risk of sudden cardiac death. We identify and characterise a novel SCN3B variant encoding the regulatory β3-subunit of the cardiac voltage-gated sodium channel, Na1.5.

Article Synopsis
- Brugada syndrome is a rare condition that elevates the risk of serious heart arrhythmias, with limited guidance on pain management for these patients.
- A case study of a young woman with the syndrome highlights the use of ropivacaine peripheral nerve infusion and intravenous ketamine for managing her acute-on-chronic pain in the left upper limb.
- The approach included a multimodal analgesia strategy with neuropathic agents and opioids, aiming to improve safe pain management practices for those with Brugada syndrome.

Brugada syndrome (BrS) is a genetic channelopathy that may predispose to ventricular arrhythmia. It is inherited as an autosomal dominant pattern with incomplete penetrance. Fever can unmask Brugada syndrome in children who have a genetic predisposition.

Background: Brugada syndrome (BrS) is an inherited channelopathy characterized by right precordial ST-segment elevation. This study investigates the clinical and genetic characteristics of children with BrS in Hong Kong.
Methods: A retrospective review was conducted at the only tertiary pediatric cardiology center in Hong Kong from 2002 to 2022, including all pediatric BrS patients under 18 years old.
