Has anyone done any research on the effects of the electrical spinal stim on people with heart electrical issues? I had two ablations done and a 3rd one that they couldn't do as it was too near the valve. I've noticed that since they finally got the stim working, I've been having more palpitations and chest pains. If I turn the stim off during the palpitations, they go away quite quickly, If I don't turn it off, they can last longer. Just wondering if anyone has heard of any research on it. I haven't found anything online, but I don't know how to get to medical websites.
