Sudden cardiac death and syncope of unknown origin: Think about catecholaminergic polymorphic ventricular tachycardia!

Sudden cardiac death (SCD) or syncope may remain unexplained after extensive cardiac investigations. However, genetic testing may help to establish a clear diagnosis in a substantial proportion of these cases. We here report our experience in 5 patients referred for SCD or syncope of unknown origin, in whom the diagnosis of catecholaminergic polymorphic ventricular tachycardia (CPVT) was given by genetic testing.
