Familial ventricular tachycardia

Idiopathic ventricular tachycardia is a generic term that describes the various forms of ventricular arrhythmias that occur in patients without structural heart disease and in the absence of long QT syndrome (summary by Lerman et al., 1998). Familial ventricular tachycardia is usually attributable to recognized conditions such as arrhythmogenic right ventricular dysplasia, hypertrophic cardiomyopathy, familial cardiomyopathy, or one of the long QT syndromes. There are families with ventricular tachycardia in which no recognized underlying condition has been identified. The features of the disorder are variable from family to family (summary by Fisher et al., 1999). See also catecholaminergic polymorphic ventricular tachycardia (CPVT; 604772). [from OMIM]
