    • Max strain represents the peak value of Heart Strain during each workout.

      Heart Strain is a measurement based on the ST-segment deviation recorded by the Frontier X from the CC5 Lead position. This deviation could be due to a variety of reasons, including oxygen deprivation to a part of your heart, electrolyte imbalance and conduction…Read More

      • Thanks for the reply. It seems that at times noise can be influencing a momentary spike in strain especially when there is movement.

    • i’ve just started with the device today. Im medical by trade (not a cardiologist no physician – im in a surgical specialty). I’m 8 years post stenting and worried about , well pretty much everything. I had a bit of a panic at my first mild exercise with the device where I had a peak strain of 0.17, but then I looked at where the peak came and this…Read More

      • Thank you. I would agree that transient spikes of less than .25 or so are not an indication of ischaemia. Thanks again for your reply.
