Sulfites put me into Atrial Fibrillation within 45 minutes. Liquids, like wine, will do it within seconds, foods take a little longer. Every time I go into Afib I end up in the hospital being cardioverted (shocked) back into rhythm. I don't think all people's Afib is caused by sulfites. However, I doubt I am the only one. Most people have no idea what they are and what foods they are in, so they would never make the connection - Carey USA
