Welcome to HealingWell. The good news is that PVC's are almost always harmless. Nevertheless they tend
to feel dangerous to those who have them and it can be hard to cope
with the cycle of fear, which leads to stress and anxiety, which often then
leads to more PVC's. You have been to the ER many times and have had the whole series of Cardiac tests so may I kindly suggest now that you work on reducing your stress level.
I know all too well how impossible things seem when the anxiety and panic cycle
takes over. But if there's one thing I can't stress enough to you, it's that
it's not hopeless. In fact, breaking the cycle is not as complicated as you may
think. Try stress-reduction techniques, such as biofeedback, meditation or exercise, or talk to your doctor about anti-anxiety medications. Another thought is looking into therapy to help you deal with your high stress.
