Hi. I so sympathize with you and am experiencing the same. Trips to ER. Heart rate spiking. I have AFIB and Aflutter. Had ablation 3 years ago. I’ve had my esophagus stretched 3 years ago. Episodes come and go in the past but now they seem be daily. I have appointment with Gastroenterologist Oct 4. Food is definitely a trigger, meat so hard to digest and swallow. Interesting about muscle relaxers helping. I was given GI cocktail (lidocaine & malox) it works temporarily. I hope we all find solutions and share the information we are given. I’ve lost weight, now eat very little. Thank you for sharing.
