I was diagnosed with celiac disease in my 20's and have IBS-C (forever). Two and a half years was diagnosed with non-sustained ventricular tachycardia. I had had non-serious palpitations off and on over the years. Best to discuss with your doctor. My diagnosis came from having worn a 48 hour holter monitor. No doctor has ever mentioned to me a connection between the colon and my heart. I tend to think in my own particular case, I inherited this from my dad who had heart issues.
