@claresmayo, I recommend calling Mayo Clinic directly to ask about their approach to Roemheld syndrome or gastrocardiac syndrome. While the term or diagnosis isn't widely used anymore, the association between heart and gut is known. As you likely know, Mayo Clinic uses a multi-specialty and multi-disciplinary approach, meaning that you receive care from a team of clinicians focused on you and your needs.

Here are the contact numbers should you wish to inquire further: http://mayocl.in/1mtmR63

Clare, what gastric events trigger your a-fib?
