Since the last week, I've noticed that my heart rate during my trainings were erratic and abnormally high.
Below, an example on a treadmill run today. I had to distance the monitor from the skin for a few seconds for it to go back to normal.
3RD INSTANCE
I still had the issue after changing the battery CR2032. I only noticed it once arrived at home.
2ND INSTANCE
Here is an example of the first instance. I distanced the HRM from my skin for a bit and it went back to normal before going crazy again.
I thought it might be because of my bluetooth headphones, but I have had them for a bit already.
Any update who could have caused that on January 14?
Feel free to suggest ways to help.
Here is the model I'm using
