About Video

The audio recording from a 45 years old man taken from the 3rd left intercostal space at the left sternal border is shown in this video. All of the following statements are correct except: (A) There is a short ejection systolic murmur noted, (B) There is an audible expiratory split of S2, (C) The S2 split is typical of RBBB, (D) The S2 split is typical of LBBB. The recording does show a short ejection systolic murmur which clearly ends before the S2. The S2 is split intermittent and appears to split only on expiration and remains single on inspiration. The reversed or the paradoxical split is characteristic of left ventricular conduction delay as in LBBB. The right ventricular conduction delay would result in delayed P2 with a normal sequence of A2–P2 and therefore will result in a wide physiologic split and not in a paradoxical split of S2. The LBBB is the most common cause of a reversed split S2.
