Observational (n=14)
Right ventricular dilated cardiomyopathy should be considered in patients with unexplained syncope or ventricular tachycardia with an LBBB pattern, as it carries a high risk of sudden death.

May support evaluation for right ventricular dilated cardiomyopathy in unexplained syncope or LBBB-pattern VT; leaves open sudden-death risk and needs prospective validation.
Fourteen patients with predominantly right sided dilated cardiomyopathy were studied, of whom five died suddenly. The condition is characterised by male preponderance, syncope, ventricular tachycardia, which typically has a left bundle branch block pattern on the surface electrocardiogram, and right heart failure. The diagnosis should be considered in patients presenting with otherwise unexplained ventricular tachycardia or syncope; the diagnosis may be readily missed because of the nonspecific nature or absence of signs.
