  • Thanks to Jayadev for his great support.
    My FRONTIER X2 gives great ECG’s even whilst wearing merino wool which is high in static!
    I also have no need to use heart monitor contact gel or anti static spray.
    Thanks to the team.

    • Send to your doctor for expert interpretation, but bear in mind Frontier X2’s own disclaimer, that it is not intended for medical diagnosis
