Ventricular arrhythmias

Ventricular arrhythmias encompass a spectrum of abnormal cardiac rhythms originating distal to the bundle of His within the ventricles, including premature ventricular complexes, ventricular tachycardia, and ventricular fibrillation These electrophysiologic disorders affect the cardiovascular system and commonly arise in adults with structural heart disease, such as ischemic cardiomyopathy, though they may also manifest in structurally normal hearts via channelopathies or idiopathic foci Pathoph...

These electrophysiologic disorders affect the cardiovascular system and commonly arise in adults with structural heart disease, such as ischemic cardiomyopathy, though they may also manifest in structurally normal hearts via channelopathies or idiopathic foci Clinically, manifestations range from asymptomatic palpitations to hemodynamic instability, syncope, and cardiac arrest

Pathophysiologically, they are driven by mechanisms of re-entry, abnormal automaticity, or triggered activity, producing wide QRS complexes on electrocardiography

Clinically, manifestations range from asymptomatic palpitations to hemodynamic instability, syncope, and cardiac arrest
