Heart issues started for me at 36 in peri, now at 61 I have developed a-fib. Changing hormones ramped up my anxiety causing the pvc's and pac's and I never was able to get my anxiety under control. Now I fight daily with short episodes of a-fib, still have pvc's and pac's too. Thyroid is fine, all other labs always normal, just very sensitive nerves in my atriums causing the irregular beats. Do, take, whatever your doctor recommends, living with this daily is no fun.
