Collapsing pulse
Collapsing Pulse
Collapsing pulse (pronunciation: /kəˈlæpsɪŋ pʌls/), also known as Corrigan's pulse or water-hammer pulse, is a medical term used to describe a pulse that is bounding and forceful, only to quickly collapse. It is often associated with aortic regurgitation, a condition where the aortic valve does not close tightly, causing blood to leak back into the heart.
Etymology
The term "collapsing pulse" is derived from the Latin word "collapsus", meaning "fall together", and the Old French word "puls", meaning "beat". It was first used in the medical context in the 19th century by Irish physician Sir Dominic Corrigan, hence the alternative name "Corrigan's pulse".
