  • Can anyone tell me which electrode from a 12 lead ecg is most like what we get from the Frontier X2? It sort of looks like something like V4 or V5 to me. I am not a health care pro, just a physicist that measures small signals in things like electromyography.

    • I think you’re on the right track. If my memory serves me well, Fourth Frontier has stated somewhere that the Frontier X2 is closest to the V5 lead on a 12 lead ECG.

  • I’m new to this. Is there anyone here that interprets the heart ecgs? Also what web site do I look at on my pc to see the ecgs?
