Has anyone else seen spikes like this in their heart rate? I'm sure my heart isn't actually doing this. I made sure the Watch band was tight. Apple support told me to cycle power to the Watch - no difference. They told me to unpair and then pair - no difference. They replaced the Watch - no difference. They never actually acknowledged that this is a problem they have seen before, they just seemed to be offering up solutions that they resort to when they don't know what else to suggest. I understand that the Watch heart rate algorithm might not work for everyone, but I am surprised that I have not yet found a reference to anyone else having a similar problems. Others have complained about the accuracy, but they always report the heart rate measurement to be too low, whereas in my case it spikes to a value that is way too high.
