Idiopathic Ventricular Arrhythmias
Idiopathic ventricular arrhythmias (VAs) occur with a mechanism that is unrelated to myocardial scar. Idiopathic VAs most commonly occur in patients without structural heart disease, but can occur in those with structural heart disease. Idiopathic VAs present as a sustained or a non-sustained ventri...

| 520 | |a Idiopathic ventricular arrhythmias (VAs) occur with a mechanism that is unrelated to myocardial scar. Idiopathic VAs most commonly occur in patients without structural heart disease, but can occur in those with structural heart disease. Idiopathic VAs present as a sustained or a non-sustained ventricular tachycardia or premature ventricular contractions. Imaging examinations such as echocardiography, nuclear tests, and cardiac magnetic resonance imaging are helpful for excluding any association of an idiopathic VA occurrence with myocardial scar. For the past two decades, the sites of idiopathic VA origins, commonly endocardial but sometimes epicardial, have been increasingly recognized. Idiopathic VAs usually originate from specific anatomical structures and exhibit characteristic electrocardiograms based on their anatomical background. Idiopathic VAs are basically benign, but they require medical treatment or catheter ablation when idiopathic VAs are symptomatic, frequent, or cause tachycardia-induced cardiomyopathy. This book chapter describes the up-to-date information on the prevalence of idiopathic VA origins relevant to the anatomy, diagnosis, and treatment of idiopathic VAs. | ||
