  • I’ve been using the Frontier X2 for a few weeks now. Not really interested in the workout statistics at 76yo with a lot of heart damage and diastolic dysfunction. I have a certain level of PVCs and want to track them for sleeping, walking, working, etc. The X2 is very good at identifying arrythmias and the stress level seems to monitor the S-T…Read More

      • Thank you for your response, I have a couple of other suggestions for a future update. The main one is that I would like to do a file download to my phone or Google Drive rather than to my e-mail. It seems to take forever for a file attached to e-mail to get to my inbox in gmail. Also, just caught this scary 1 minute AIVR episode yesterday. I…Read More

      • Wet the shiny, skin-facing sensors on the strap with a few drops of water before wearing it. In cold weather, the skin can be dry and may…Read More

  • How to interprete my ECG is ok or not
    How to know if there is any defect or not in ECG

  • Not sure if this has been mentioned, but I just discovered that my X2 has a great new use. I’ve had the X2 for a year and a half and I’m loving it–I have exercise-induced Left Bundle Branch Block and my X2 has been invaluable in showing me (on the ECG) exactly when I get LBBB, which allows me modify my training and medication schedule effectively…Read More
