Funny story. I have occasional irregular heartbeats. A number of years ago I was given a monitor to take home and use periodically when I was getting episodes of skipped beats.
This was a while ago, and after I ran it for about an hour I was supposed to call a phone number and basically modem in the data.
I dutifully uploaded my episodes for a few weeks, and apparently the doctor or specialist who was reviewing the data saw nothing out of the ordinary.
With a friend of mine we decided to reverse-engineer the signal the device was making to the telephone. It turns out it was a simple frequency modulation of the EKG Trace.
Long story short, we found the skipped beats, printed out the traces, presented our own printouts to my doctor and confirmed a diagnosis of premature atrial contraction.
