Implication

Isolated RBBB may warrant familial evaluation; leaves open whether genetic testing improves outcomes in this rare entity.

Structured PICO

Population

Families of two children with isolated complete right bundle-branch block (n=91 evaluated: 69 in one family, 22 in another), descendants of a common ancestor in Sweden.

Intervention

Electrocardiographic screening and genealogical tracing

Outcome

Presence of classical complete right bundle-branch blocksurrogate

Isolated complete right bundle-branch block can be inherited as an autosomal dominant genetic anomaly with reduced penetrance and/or expressivity.
