pulsometer

[zabujco]

Hi,
are there any experts from electronics here? I would like to do a heart rate monitor, which I could connect to the computer and see online my heart rate, make graphs during apnea and so on. maybe someone already did something like that and could give me the instruction how to do it? I think I could do a program myself and the pulsometer itself can be bought, but a problem is how to do an interface which would send the pulsometer's data to the computer (I haven't seen such an interface on market).
If you saw anywhere documentation of such an interface please let me know.

Suunto offers such equipment for retail customers with the new T series and the corresponding PODs. However you might run into problems being under water (they have an optional belt that stores the data under water but in this case you won't be able to see it online, only after transferring it to the PC)
