Just a thought: I also have PVCs and palpitations. If you not have a complete thyroid panel done, please go to an endocrinologist. Palpitations can be caused by Thyroid Disease. Primary physicians tend to not do a complete thyroid panel. My palpitations increased after Covid and finally stopped about 3 months later. Palipatations and PVCs alone can make you feel anxious. I was diagnosed after wearing a heart monitor by a cardiologist, I pay them no mind now. When I get the palpitations, I know that my thyroid is "out of whack" again. I have Graves Disease as well....so I alternate between Hypothyroidsime and Hyperthyroidism. I take methamazole for Graves Disease and get bloodwork every 3 months as well as an ultrasound of my thyroid with my endocrinologist.
