Corrigan's pulse
Corrigan's Pulse
Corrigan's pulse (pronounced: kor-ri-gan's pulse), also known as water-hammer pulse, is a medical term that describes a specific type of arterial pulse associated with aortic regurgitation. The term is named after the Irish physician Sir Dominic John Corrigan who first described it in the 19th century.
Etymology
The term "Corrigan's pulse" is derived from the name of Sir Dominic John Corrigan (1802–1880), an Irish physician who made significant contributions to the understanding of cardiovascular diseases. The alternate term "water-hammer pulse" is a descriptive term that refers to the pulse's characteristic feel, similar to the sensation of a water hammer in a pipe.
Description
Corrigan's pulse is characterized by a rapid upstroke and collapse of the arterial pulse. This is due to the rapid ejection of a large stroke volume into a non-compliant aorta, followed by rapid runoff of blood into the periphery during diastole. This phenomenon is typically observed in patients with significant aortic regurgitation.
