Social determinants of health (SDOH) were found to be associated with increased risk of heart failure (HF) and ventricular arrhythmias (VA) in patients with hypertrophic cardiomyopathy (HCM), ...

Hearts of young cyclists show greater exercise-related adaptation, including more left ventricular enlargement and changes on ...

Ventricular arrhythmia occurs when the heart’s lower chambers beat out of sync, which can prevent the heart from effectively pumping blood throughout the body. Diagnosis of ventricular arrhythmia ...

Monomorphic ventricular tachycardia is an irregular heartbeat where the bottom chambers of your heart beat quicker than usual. It can cause symptoms such as shortness of breath, dizziness, or fatigue.

The His–Purkinje system constitutes a tiny fraction of the ventricular mass, but is specialized for rapid synchronous activation of both ventricles The pathogenic role of the Purkinje system is ...

Although premature ventricular beats (PVBs) in young people and athletes are usually benign, they may rarely mark underlying heart disease and risk of sudden cardiac death during sport. This review ...
