This seems to come from the bromide getting pushed out of the tissues and into the bloodstream. It's not getting out of the body fast enough through the kidneys so it acts like an anti-iodine, slowing down the metabolism and irritating the heart.
Is the client(pulse dosing)stopping Iodine for 48 hours every five days? Salt loading every day?
That should help the bromide blow back.
Please let us know. I've seen some good results with Afib but not while the bromide is running free.
