Anyone experiencing post covid heart issues?

I am much older 56, but yes, I too have pots now, not after covid rnd 1 in Nov of 20 , but after rnd 2 jan of 22. I went thru all the tests and they say I stay in sinus rhythem so its autonomic, Nerves. So far no fix. Sorry wish I could help you. Mine is worse durring a flare. When in a flare everything is worse. By flare I mean, headache tired(worse than usal) muscles tenser, sorer...My flares come by over doing. Dehydration. Stress. on a good day I am up to 20 min walks(not fast paced). On a bad day the typical 10 min will do me in. a shower 160, dishes 140... pace your self, dont over do. Learn your breathing exersizes, deep belly breaths, exhale thru mouth slowly, it calms you...good luck, prayers!

When I finally got into a cardiologist he said he is seeing this a lot. I had a 21-day event monitor which showed the palpatations/rapid heart rate at rest and what happened when I stood up. The final diagnosis is "Inappropriate Sinus Tachycardia", a fast heart rate that is not appropriate to level of physical activity. I was put on Metoprolol, a 'Beta-Blocker', which has controlled the heart rate. I can still have runs of palpitations but they are less common and not as fast. It has helped my energy as well since I don't feel like I am starting a sprint every time I stand up.
Take your time changing positions (lay to sit, sit to stand) to avoid dizziness/passing out.

I was a very healthy, active person before COVID, then started the same symptoms about 1 month after infection-that was 1 1/2 years ago when there was little research available to doctors. Finally, I got a '21 day Event Monitor' order from my PMD; a holter monitor is for too short of a time. It was the final evidence of 'Inappropriate Tachycardia'-a heart rate disproportionate to my activity. My cardiologist tells me he is seeing this a lot with his covid patients, and not necessarily those who were hospitalized. I am now on Metoprolol for heart rate control. There is a lot of information on nih.gov, the National Institute of Health; look under COVID and Tachycardia (fast heart rate). There are several possible diagnoses-POTS is certainly one. CDC's website also has great info-you are not alone.
I kept a daily journal, documented my activity (walking at slow, normal, fast rate, climbing stairs, towel drying after a shower, laundry/folding sheets, at rest, getting up and walking after sitting) and heart rate to show the data to my PMD. My heart rate went to 150 washing my hair!! My EKG, Stress Test, Echocardiogram, a test that had me riding a bike and hooked to a monitor.... were all "normal". I am an ER Nurse with 40 years of experience and ran a half marathon for my 60th birthday. I have a lifetime of knowledge about heart rates. It took a LOT of persistence to get the Event Monitor which objectively confirmed the symptoms.

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.

That definitely sounds like POTS. I was diagnosed with POTS after having covid. It’s been 9 months and still have the issue. I’ve gotten used to it so it’s less alarming, but is the cause for the extreme fatigue.
You need to see a cardiologist, especially if you’re experiencing pain too.

Definitely get all the testing done to rule out myocarditis and structural/functional issues. I am 10 months post Pfizer booster and only now starting to pull out of this a bit- seems to be autonomic nervous system stuff as all my tests are normal for structure and function. I did test positive for autoimmune markers, inflammation marker and have really high histamine levels so I take a bunch of supplements and am doing a low histamine diet. I start with a functional dr this week. I also found a return to activity protocol adapted from POTS to long covid heart reconditioning so I’m slowly rowing my way back to a mellower less flighty heart. I’m happy to talk more! It’s a non linear process though…
