The Gallavardin phenomenon is a
cardiac apex.[1] The presence of a murmur at the apex can be misinterpreted as mitral regurgitation. However, the apical murmur of the Gallavardin phenomenon does not radiate to the left axilla and is accentuated by a slowing of the heart rate (such as a compensatory pause after a premature beat) whereas the mitral regurgitation murmur does not change.[2]
The sign is named after Louis Gallavardin, having been described by Gallavardin and Ravault in 1925.[3]
