When I saw a cardiologist for my PVCs he told me that I had no scarring or inflammation in my heart, that the rhythm I was having is caused a bigemini rhythm and it's a non harming thing. He told me that if it really bothers me there's things that can be done, but said for now let's see you again in 6 months and see how you are. I was out on metropanol, but had to stop taking it as it was making my blood pressure really low.
Lol sorry, but yes COVID 3 years ago PVCs off and on ever since up until heart attack . Mind you I am 54, smoked up until heart attack, but really I was super healthy until COVID. Insomnia, tinnitus, PVCs, shortness of breath all started within 3 weeks of having it. Tinnitus went away after heart attack for awhile, but the crickets in my ears are singing loud as ever now once again..

I've been throwing PVCs my whole life. Mine are also caused by the electrical circuitry in my upper left chambers of my heart. They worsened about a year ago but not from COVID but just from the fact they're getting worse. Diagnosed with supraventricular tachycardia with PVCs . I also and taking toprol...metoprolol. It's helpful to not drink thinks with caffeine, sugar, or a lot of carbohydrates and to stay as stress free as possible. Get plenty of restful sleep. I take melatonin every night to help get better rest. Don't smoke or drink alcohol. Be consistent with the time you take your medicine. Instead of taking mine in the once daily dose, I break it in half and take it twice daily as I have found of I take the whole dose just once daily my system absorbs it too quickly which causes my symptoms to increase. Good luck and I hope I've given you some good pointers that you may find beneficial for you also. It's all trial and error but I must say that after as long as yours has been going on, you too have probably had this prior to COVID but just not to the extent that you ever noticed it. COVID just brought it on more extreme. Unfortunately it's usually a lifelong thing once it starts. That's why it's important to do things to help improve the control of it so the meds will help control it more efficient. Good luck!

My husband finally ended up with AFIB and a cardio version was done. The AFIB didn't stay gone, but his heartbeat slowed down to a proper speed and he is better. For autonomic calming, look at EFT Tapping, intentional breathing.
