The past few weeks, my displayed pulse rate on my fitbit will go up for no reason. I test it with my finger on my wrist and it's normal. This happens during excercise too. I've reset it several times. Moved and adjusted the wrist placement. Switched wrists. It's completely arbitrary but scares the xx out of me. No AFIB notifications. It does show up on work outs but the spkie is lower. Is this common?
