In Corrigan Pulse is all are true except
Corrigan's pulse also called water-hammer pulse
Characterized rapid carotid upstroke during systole and rapid fall in pressure is during diastole.
This happens due to cardiac output with reduced resistance.
In the case of aortic regurgitation left ventricle is dilated this produces large cardiac output during systole. But in diastole, blood flows back into the low-pressure left ventricle this produces rapid fall in pressure leading Corrigan's pulse
In case the of the artery to the venous fistula, there is increased cardiac output due to hyperdynamic circulation. Diastolic pressure is decreased because the flow of blood happens to the low-pressure venous system this produces Corrigon's Pulse.
Pulse pressure means the gap between systolic and diastolic pressure. This is increased in Corrigan's Pulse
Effectively all cause of hyperdynamic circulation can produce Corrigon's Pulse
Causes of Corrigan's Pulse are
|Cardiac lesions||Hyperdynamic circulatory states include||Physiological etiologies include|
|Patent ductus arteriosus||Anemia||Fever|
|Aortopulmonary window||Paget disease||Pregnancy|
|Sinus of Valsalva rupture||Liver cirrhosis|
|Leaking aortic valve prosthesis||Thiamine deficiency or beriberi|
|A ventricular septal defect with aortic regurgitation||Systolic hypertension|
|Truncus arteriosus||Arteriovenous fistula|
|Mitral regurgitation||Cor pulmonale|
|Complete heart block|
