A hyperkinetic pulse occurs in the setting of an elevated stroke volume (anemia, fever, anxiety) or an abnormally rapid runoff from the arterial system (aortic regurgitation, patent ductus arteriosus, arteriovenous fistula).
The hyperkinetic pulse is characterized by an increase in the velocity of the upstroke and amplitude.
Hyperkinetic pulses may be associated with anxiety, exercise, fever, thyrotoxicosis, hypertension, aortic regurgitation, arterio-venous fistula, and patent ductus arteriosus.
Patients with marked bradycardia may compensate with a large stroke volume clinically manifest by a hyperkinetic pulse.
The water-hammer, or Corrigan’s, pulse is characterized by a very brisk upstroke, large amplitude, and rapid collapse; it is an extreme form of the hyperkinetic pulse.
