Does anyone know of any studies that link maximum breath hold times to average heart rate and/or number of heart beats during the hold?
I know that metabolic rate, heart rate, and O2 consumption rate are pretty closely correlated. Therefore, it seems like it should be possible to estimate how quickly you are burning through oxygen based on your heart rate preceding and during the dive.
It would be really handy to have a computer that could estimate how much time you have left before you are at risk for a blackout, particularly if you are going deep enough that ascent blackout is a concern.
