A bounding pulse in an infant may be associated with:
a. patent ductus arteriosus.
b. coarctation of the aorta.
c. decreased cardiac output.
d. peripheral vaso-occlusion.
A
A bounding pulse is associated with a large left-to-right shunt produced by a patent ductus arte-riosus. A weaker or thinner pulse represents diminished cardiac output or peripheral vasocon-striction. A difference in pulse amplitude between the upper extremities or between the femoral and radial pulses, and absence of the femoral pulse, suggest a coarctation of the aorta.
