Gabriela - Yes, GERD can cause arrhythmias. I've posted quite a bit about
my experiences and the topic of "cardioesophageal reflex" (with an e, not a u) or "linked angina." You can read the posts by putting those terms into the search box, right up under join healing well, at the top of the page. You can also google the terms. A lot of my posts are found by google also.
My triggers are mostly from sulfite sensitivity, which you can also google and search. If I eat something with more than my tolerance amount of sulfite preservative or natural sulfite (pork, onions, etc.) it will cause reflux which triggers arrhythmias, usually sinus tachycardia. A lot of people have posted about
this trigger on the allergy forum.
