Persistently Split S2

A persistently split S2 describes the presence of a split S2 on expiration that widens further upon inspiration. The most common cause of a persistently split S2 is a right bundle branch block, but it can occur whenever there is prolonged right ventricular ejection, such as outflow obstruction, pulmonary hypertension, or increased RV output.
