Hi sir.. dealing with fast heart beat problem, especially after eating any food rate jumps to 110/120.. though normal range but feel abnormal- palpitations, pounding feeling in chest... Ecg's done always show sinus tachy... tried medicines like metaprol, etizolam, pantosec, ulgel but no improvement... heart rate remains elevated for at least an hour.... i want to know whats causing this?? My gp has ruled out every common cause- thyroid, lft, kft, anaemia, no stimulant usage, no anxiety He now thinks that it can be gastric cardio syndrome. Plz suggest what do tou think??
