If there's a discrepancy in the heart rate data, it might be due to incorrect or non-standard wearing of your device, such as the strap being too tight or too loose, or moving your arm during the measurement.
Proper Measurement Method: Keep your arm flat, relaxed and still, and make sure the wristband fits snugly around your wrist.
Note: Heart rate data is for reference only and should not be used for medical diagnosis.
