Solis-Cohen1 has recently called attention to a peculiar heart sound heard in the tricuspid area among normal individuals, which is designated as the xiphosternal crunch. His report emphasized that:
1. It occurred in 17.8 per cent of 4,982 normal Army inductees and in 21.1 per cent of the last 3,115 of this same group who were studied more carefully. It is apparently a normal functional sound.
2. It is commonly misinterpreted as indicating mitral or tricuspid regurgitation, pericarditis or congenital heart disease.
3. It is described in only one of the standard texts on physical diagnosis.
