Our patient’s peripheral pulses are hyperkinetic.
Markedly enhanced, or hyperkinetic pulses, may occur when there is an increased velocity of contraction associated with an increased stroke volume, or preload, and a decreased resistance, or afterload. Causes include significant aortic regurgitation, patent ductus arteriosus, and a peripheral arteriovenous fistulae.
When there is a very wide pulse pressure, several peripheral pulse findings may occur, including:
Corrigan's or a waterhammer pulse, demonstrating abrupt distension and collapse;
Traube's sign or pistol shot sounds, referring to sharp systolic sounds heard over the femoral arteries;
Duroziez' sign, consisting of systolic and diastolic "to and fro" bruits heard over the femoral arteries using light pressure on the stethoscope; and
Quincke's sign, referring to visible capillary pulsations with alternate blanching and flushing of the nail beds.
