I remembered reading something awhile back about a study that Fitbit was doing about an elevated heart rate indicating Covid infection. Out of curiosity, I checked my Fitbit data and my resting heart rate is currently the highest its been in quite awhile (I normally am between 71 and 74 and yesterday and today am 77). Not a huge spike, and there could be other factors involved as it has been that high at different points before, but since I tested positive today, I'm curious if anyone else has noticed that trend? The articles I found were from the summer and noted that infection correlated with higher heart rates for months after, longer than for patients with other infections such as the flu. The article did not mention if vaccination had any effect on numbers.
