hI i i have been having problems with afib and heart flutter. It seams to be triggered always by drinking cold water ALWAYS! My cardiologist says drinking cold water has nothing to do with heart rhythm and insist that i take heart rhythm medicine and it makes me feel like crap when i am working. I have been researching the vagus nerve and seams like a avenue to try but he does not seam open to anythingbut pills. I have seen two doctors now with the same results, i live in the seattle area is there any doctors here that you can recommend that think outside the box i take enough pills already for ankylosing spondylitis. thanks Ken
