Hi Garmin Community,
Today I noticed something strange — the optical heart rate sensor was showing a much higher heart rate than usual. For example, while walking to my workout, I checked my pulse — the optical sensor showed around 100 bpm. Then I connected my chest strap, and it showed 70 bpm. I thought, okay, maybe just a small difference.
I finished my workout and walked home at a normal pace. Later at home, I noticed that the recorded heart rate during the walk back was unusually high and didn’t match how I actually felt.
Screenshot 1 – Abnormal heart rate:
This shows the issue — an unusually high heart rate recorded while walking calmly after the workout.
Screenshot 2 – Normal heart rate (for comparison):
This is from a similar walk on a previous day, where the heart rate looks normal and realistic.
Between the workouts, I didn’t update the watch software, but there was an update for the Garmin Connect app. I understand this most likely doesn’t affect the issue — just mentioning it for clarity.
Has anyone else experienced a similar issue recently?
Thanks!
