Having PVCs, Taking Testosterone, Switched From Synthroid To Armour Thyroid. Have Low BP. Culprit?

I am a 56 year old female. I had a 100 mg testosterone pellet implanted four months ago and a 112.5 mg pellet implanted July 24. Late July I started having PVCs. Holter monitor found 8000 in one day. I had also switched from Synthroid to Armour thyroid and added Slo- niacin five weeks before the PVCs kicked in. My last year, and especially the last month have been very stressful. My echo-stress test showed my heart was in good shape with no blockages. I ve stopped all caffeine. My electro physiologist said this was a benign arrhythmia, but he prescribed Flecanide which I have chosen not to take. My blood pressure is usually quite low, so beta blockers and calcium channel blockers aren t appropriate for me. Are one of the above variables likely the culprit for bringing this on? I also struggle with hypoglycemia. I take calcium, magesium and potassium, but don t know if I have the right doses. Thanks for your help.

dear patient

usually pvcs are related to an automatic focus of the heart and unfortunately you dont have much control over them, and the most you can usually do is to stop caffeine, other stimulating substances and try relaxation techniques; 8000 pvcs in a day is a decent burden; one of the options since you have such intolerance to medications is to consider a radiofrequency ablation; I would encourage you to discuss further with your electrophysiologist
