An Unusual Cause of a “Double Pulse”

We report an unusual cause of a dicrotic pulse that was detected in a patient with no underlying cardiac disease. We postulate that this was the result of elastic recoil from a huge abdominal aortic aneurysm. The palpable double pulsation of either a dicrotic pulse or pulsus bisferiens is evidence of significant cardiac disease but may be associated with other cardiovascular pathology.
