LBBB is diagnosed on a 12-lead ECG. In adults, it is seen as wide QRS complexes lasting ≥120ms with characteristic QRS shapes in the precordial leads, although narrower complexes are seen in children. In lead V1, the QRS complex is often entirely negative (QS morphology), although a small initial R wave may be seen (rS morphology).
