I am on round 2 of long covid. I had it last July 2021 and had it again in May 2022. This time is much worse, going on 4-5 months now. I was feeling better but was exposed again. My body fought it off, but I now have an autoimmune response to anything, including increased heart rate, not appropriate for activity level. I can be sitting an it is 95. Stand up and its 110. And I am in excellent physical health. I am a high intensity athlete at my usual level. I have been on metoprolol already for a POTS like syndrome. It helps some. But I feel like you have to just wait these episodes out and they go away. This time the palpitations are terrible. My cardiologist diagnosed me with LGL syndrome. A shortened PR interval. He says it is benign, which gives me some sort of comfort. So a week ago, I was feeling better, and decided to get botox. I had the same cascade of long covid symptoms with heart rate elevations and palpitations. It just keeps getting crazier! I give up on trying to figure it out.
