Brugada syndrome is an ion channel disease which is associated with an increased risk of sudden cardiac death. Most probably the pathogenesis of ventricular fibrillation in these patients is a combination of both genetically determined repolarisation abnormalities and conduction delay in the right ventricular epicardium. The highest risk of sudden cardiac death is present in patients who have experienced syncope before, who reveal the pathognomic electrocardiographic changes already at rest and who have inducible ventricular fibrillation. Asymptomatic patients who have the J point elevations only after administration of a sodium channel blocker seem to be at lower risk. Most recently the latest joint consensus recommendations of the largest societies for diagnostic criteria, indications for genetic testing and therapy have been published.

Background: Risk stratification for sudden cardiac death (SCD) in patients with nonischemic cardiomyopathy (NICM) remains challenging.
Objectives: This study aimed to investigate the impact of epicardial adipose tissue (EAT) on SCD in NICM patients.
Methods: Our study cohort included 173 consecutive patients (age 53 ± 14 years, 73% men) scheduled for primary prevention implantable cardioverter-defibrillators (ICDs) implantation who underwent preimplant cardiovascular magnetic resonance.

This state-of-the-art review examines disparities in the diagnosis, management, and outcomes of cardiac arrhythmias globally. These arrhythmias include atrial fibrillation, ventricular tachyarrhythmias underlying sudden cardiac death, and bradyarrhythmias associated with sinus node and atrioventricular node disease. Arrhythmias in low- and middle-income countries often result in higher mortality rates due to complex and poorly documented risk factors, lack of clinical expertise among health care personnel, lack of sufficient infrastructure, and challenges in access to care.

This study sought to investigate whether the prolonged QTc was associated with HCM-related death in patients with HCM.
Methods: We included 445 patients with HCM (mean age 51 ± 16 years, 67% men).

Current guidelines recommend cardioverter-defibrillator (ICD) programming, including faster detection rates, longer detection durations, and strict discrimination for supraventricular tachycardia (SVT) to prevent unnecessary ICD treatment. This delayed-style ICD programming could lead to a rise in the possibility of VF undersensing. To avoid this risk, an innovative algorithm known as VF Therapy Assurance (VFTA; Abbott, Sylmar, CA) has been developed.
