Eating certain foods seem to trigger atrial flutter for me - especially wheat. I do have a small haitil hernia, and regurgitate while eating sometimes. It seems as if my esophagus goes into a spasm before the flutter. I was diagnosed with IBS several years ago, and also have been treated for h pylori in the past. Could my stomach issues be the cause of my flutter. Should I ask my cardiologist about certain tests. He says I only have flutter, not fib. I am 56 year old female, 5'6", 128lbs. Take synthroid for Hypothyroidism, due to hashimoto. Some drs. say mitral valve prolapse, some drs say not..
