Ventricular fibrillation (VF) is characterized by rapid (>300 beats a per minute), irregular electrical activation with variable electrocardiographic waveforms that prevents coordinated myocardial contraction, resulting in immediate loss of cardiac output.1 It most commonly occurs in the context of coronary ...
Cardiovascular care continues to evolve in response to increasingly complex clinical realities, where advances in intervention, electrophysiology and population health must be integrated with a more critical appraisal of long-held assumptions. Across disciplines, there is a growing recognition that improving ...
Sudden cardiac arrest (SCA) in young adults (typically defined as individuals younger than 40 years) has emerged as an important yet under-recognized public health concern. Recent estimates suggest an incidence of approximately 1–4 cases per 100,000 person-years, underscoring the clinical and epidemiological relevance ...
At EHRA 2026, Ben Petrazzini discussed new research that shows AI can improve identification of sudden cardiac death in electronic health records, enabling more accurate large-scale studies and advancing prevention strategies.
Hypertrophic cardiomyopathy (HCM) is a genetic cardiac abnormality characterized by left ventricular hypertrophy and diastolic dysfunction, primarily attributed to mutations in genes that encode sarcomeric proteins.1,2 The disease manifests in two broad phenotypes: obstructive HCM (oHCM), defined by dynamic left ...
The current outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has developed into a worldwide pandemic affecting millions of lives in one way or another.1 Over the period of 1 year since the disease was first ...
Several closely regulated ion channels are involved in the various phases of the myocardial action potential (phases 0–4) (Figure 1).1 In the absence of neuroendocrine and other regulatory signals, the pacing rate of the sinoatrial node is 100 beats per minute (bpm). However, ...
Introduction: Sudden cardiac arrest (SCA) in sport is a tragic event. Elite footballers are at increased risk compared with the general population. The risk in non-elite but competitive individuals is unknown. Rapid response to SCA events is critical to ensure ...
Introduction: Implantable cardiac defibrillators (ICDs) are a lifesaving therapy for children at risk of life-threatening arrhythmias. Often, such children will present with sudden cardiac arrest, and ICDs are vital for secondary prevention of further life-threatening events. If high-risk young patients ...
Introduction: Cardiac arrest in relatively young patients is a difficult presentation to manage, with multiple potential causes. Establishing an accurate diagnosis is crucial and has implications on first-degree relatives. Here we present the case of a 56-year-old female with a ...
Athletes represent the fittest individuals in our society, yet paradoxically carry an increased risk of sudden cardiac death (SCD) when compared to sedentary individuals with the same cardiac disease.1,2 Two recent studies have provided a realistic prevalence of young SCD ...
Coronary artery disease (CAD) is a major global cause of death attributing to nearly 9 million deaths worldwide in 2016.1 The introduction of percutaneous coronary intervention (PCI) has revolutionised the treatment of CAD in current clinical practice, and advances in coronary stent ...
A survivor of cardiac arrest due to ventricular fibrillation (VF), without a cardiac, respiratory, metabolic, or toxicological explanation, is diagnosed with idiopathic VF.1 Idiopathic VF is estimated to account for approximately 5–7% of all out-of-hospital cardiac arrest cases.2,3 Furthermore, the Cardiac ...
Dr Artur Fedorowski briefly explains sudden cardiac arrest. Filmed at the Heart Rhythm Congress (HRC) 2019 in Birmingham, UK, October 2019 in partnership with Arrhythmia Alliance.
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice, and catheter ablation of AF is currently one of the most commonly performed electrophysiology procedures. Growing experience with ablation techniques, and better AF suppression compared with antiarrhythmic ...
Brugada syndrome (BrS), first described in 1992, is an autosomal dominant, arrhythmogenic disease. There is a male predominance of the syndrome and the prevalence is highest in Asian and Southeast Asian countries, reaching 0.5.1 per 1,000.1 BrS is diagnosed in patients with ST-segment ...
Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare, inherited non-ischaemic cardiomyopathy, which is linked to a high incidence of recurrent ventricular arrhythmias (VA) and sudden death, especially in young and athletic people. The purpose of this study was to ...
