Abstract
|
|
|
|
Ventricular arrhythmias (VAs) in structurally normal hearts can be broadly considered under non-lifethreatening monomorphic and life-threatening polymorphic rhythms. VAs are commonly seen in young patients and typically have a benign course. Monomorphic VAs are classified on the basis of the site of origin in the heart, and the most common areas are the ventricular outflow tracts and left ventricular fascicles. The morphology of the QRS complexes on an electrocardiogram is an excellent tool to identify the site of origin of the rhythm. Treatment options include reassurance, medical therapy, and catheter ablation. Very frequent ventricular ectopy may result in cardiomyopathy in a minority of patients.
