I had an SO with a "valve job". When it was quiet, I could hear
her heart "clicking". Could tell to some degree her mental state,
as much as it was reflected in her pulse. But the times when I would
have liked to know, things were usually too noisy to hear that little
clicking sound. Sigh.


Clicking is good! When the clicking stops...not so good.

Some of the implantable defibrillators are equipped with a high pitched tone
activated by certain circumstances. It is amusing to watch hospital staff
freak out at the high pitched tone emanating from patient's chest (if you
have never encountered it can be a bit unnerving).
