This ECG is from a 91-year-old man who was being evaluated for replacement of his aortic valve, which was severely calcified. It shows a classic LBBB pattern: wide QRS, supraventricular rhythm (normal sinus rhythm with first-degree AV block), a negative QRS in V1, and a positive QRS in Leads I and V6.
