Less ham and more hip radio, hospital staff in the US appear to have been rocked when a Doppler used to assess their patient’s pulse after a hip dislocation played a catchy Mexican melody,  called Thanks for your love, instead.

The 65-year-old man, who had previously undergone total arthroplasty of both hips, presented to hospital with a dislocated right hip after a fall.

However, when staff placed the handheld Doppler device on the dorsalis pedis, the probe picked up an entirely different kind of beat, in addition to the patient’s pulse.

The song — Gracias Por Tu Amor by Banda El Recodo De Cruz Lizárraga — could be heard every time doctors held the device against either of the man’s feet (watch the video here) and occurred even when they used other Doppler devices.
