Hello,
Since you have a history of gastritis you should take high fiber diet & plenty of water. Take antacids, PPI's to avoid triggering of the heart beats.
Irregular heartbeats with the fluttering of the chest are commonly indicative of Atrial
Fibrillation.
You are suggested to visit ER & get physically examined, get CBC,
Urinalysis, ECG,
Echocardiography,
Lipid profile, stress tests done to rule out any developing cardiac disease(
valve disease).
Limit alcohol intake, cut on high purine diet, stay away from stress & greasy food, do regular exercises.
Your treatment will depend upon the severity of the pathology detected. You may need beta blockers, anti-arrhythmic drugs, anti-coagulants, etc. Take medications under your cardiologist.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
