| cardiorespiratory murmur | <cardiology, clinical sign> An innocent extracardiac murmur, synchronous with the heart's beat but disappearing when the breath is held, believed due to movement of air in a segment of lung compressed by the contracting heart. Synonym: cardiorespiratory murmur. (05 Mar 2000) |
