Im 44 Had Heart Palpitations For Some Time. Now I

Im 44 had heart palpitations for some time. Now i take take metoprolol its been 5 months. Sometimes i have episodes that my heart rate shoots up from resting to up to 92 98 bpm some times i know if i eat something with high salt content does trigger it that's why at the movies now i do not eat any goodies popcorn corn chips etc...But for a long time i notice when my stomach acts up have the urge to pass my bowels i get dizzy my heart rate goes up can there be an issue with anything from my stomach or small intestine that could cause these symptom because it has been the case every single time. Now i eat very as healthy as possible i dont smoke or drink like i used to i may have a beer bottle a month and do my best to avoid all the salty bad stuff. Any way that's my question
