  • A man who had hip replacement surgery went to hospital after sustaining another injury
  • Upon his arrival, doctors took his pulse
  • Instead of only a heartbeat, Mexican music could also be heard

American doctors were blown away when they checked the pulse of a 65-year-old man and heard music playing. A report, published in The New England Journal of Medicine, stated that the man previously underwent a bilateral hip arthroplasty (hip replacement surgery) and had to return to hospital after sustaining a fall and dislocating his hip. 

The doctors used a Doppler – a tool used for prenatal ultrasounds and heartbeat – to check the man’s pulse. Something completely unexpected occurred as they tried to observe his heartbeat: along with the thumping of his heart, music came blasting through the speaker of the ultrasound device. 

Mexican music from patient’s feet

According to the report, the music could only be heard when the device was placed on the man’s feet. The hospital staff even tried using the device on themselves to test if the same would happen, but the music only came from the man’s pulse in his feet.

An application named Shazam (that identifies music) revealed the name of the song was "Gracias Por Tu Amor" by the Mexican band, Banda El Recodo De Cruz Lizárraga. One of the suspected reasons for the music, according to the authors, is that the Doppler may have picked up radio signals that were being projected through the patient’s prosthetic hips.

Another possibility is that another piece of equipment in the room was receiving a radio signal, which was picked up by the device. The doctors had the device tested by engineers to assess whether it was faulty, but they found it to be working optimally.

The report also stated that eight months after his strange hospital visit, the man was doing well, and no more music could be heard along with his
