I experienced an unusual heart rate reading during a run yesterday and I'm trying to understand what might have caused it. I was about 1 hour into my run, listening to music through Spotify on my Garmin Venu 4, when my heart rate suddenly jumped from 150 bpm to 192 bpm. The thing is, I didn't change my pace or effort level at all - I was running exactly the same as I had been for the previous hour and felt completely normal. The elevated reading of 192 bpm stayed like that for approximately 3 minutes, and then it dropped back down to 150 bpm on its own and remained stable for the rest of the run.
Any insights or troubleshooting suggestions would be appreciated, as I want to make sure my training data is accurate going forward.
