Doctors hear Mexican song while checking pulse in 65-year-old US man's feet
A 65-year-old US man, who had undergone hip-replacement surgery, visited a hospital after experiencing a fall and dislocating his hip. When doctors assessed pulse in his feet using a Doppler device, they heard a Mexican song playing through the device's speaker. Doctors assume that Doppler might've picked up a radio signal that was being received by the patient's prosthetic hips.
