Day 11 of Covid. Feeling much better than I have been in some ways but overwhelmingly exhausted. Have been keeping an eye on my heart rate and oxygen levels using a pulse oximeter. Oxygen levels have been pretty stable, had a few days where it would drop to 91/92 but with deep breathing I could get it back up to an acceptable level. Resting heart rate between 70-80, rising to over 100 when moving around.
Today I'm feeling very lightheaded (more than the previous 10 days), heavy feeling in my chest and shaky. Oxygen levels very good, 96-98. But resting heart rate hovering around 50-55 rising to 70ish when moving. Lowest has been 48. I've always associated high heart rate with a problem, low = good. But wondering if this is normal or I should be speaking to someone? Anyone know much about low heart rates? Contrary to how I'm feeling, could this just be a good thing?
