heartbeat statistics

[ecg15]

who sends or uploads his/her overnight heartbeats (ECG or oximeter or stethoscope
or whatever, but computer-readable,non-encrypted format, compression is ok)
gets included in my comparison and gets the charts of the heartbeat-frequencies
and list of irregularities.
I also want to upload the comparison of charts from those who don't mind to be included
in the public charts (without names)

At this time I just want the timings of heartbeats, regardless of the exact waveform.

So far I've got 18 nights of mine, with occasional missing beats (maybe due to
cable problems) or small periods
(~10sec-~10min, rarely just one fast beat, but that did occur also)
of fast beats

Maybe later I can do the same with SpO2 or ECG waveforms or other parameters ...,
if there is interest
