Heart Rate 238
Not really. Most rides I get one or two spikes of 238. Like it's the default high.
Clearly an error. It's annoying because it throws my cool looking graph off.
I use a Garmin 235. I have an auxiliary chest strap that seems a lot more accurate. I get these spikes using it or just the wrist sensor.
Fwiw, at full capacity, and possibly trying to kill myself, I probably can get to mid 180s. I've seen mid 170s and I'm pretty sure I would forget how to read if I went past that. So yeah, no chance I'd hit 238. I'm somewhat older than 2.
Power lines? Cell signals? Contrails?

I used to get those glitches around the bigger power lines. Now I live in a community with underground utilities and I still get them now and again. ��*♀️

My heart rate monitor is pretty stable, Garmin 810 with cheststrap. I also wear a Garmin Vivosmart watch sometimes, and they don't always agree, but are pretty close. When off the bike I sometimes see high readings on the Garmin watch, compared to my activity, but never over 160 or so. A friend of mine has a Specialized cycle computer. One day while stopped in a left turn lane over a traffic sensor, she looked down, and her cyclometer showed 154 mph, standing still. Stuff happens.

Heart rate monitors sometimes double-count beats, counting the atrial spike as a separate beat from the ventricular spike. As an RN who worked in cardiac care, we had a motto: "treat the patient, not the monitor." When you see an anomalously high (or low) reading, directly palpate a pulse to verify.
A true heart rate of over 200 would likely be symptomatic, as cardiac output will decrease if the rate gets so high the ventricle can't fill between beats.
