I understand your concern and would explain that your symptoms seem to be related to gastroesophageal reflux. I recommend consulting with your GP for a careful physical examination, and some tests:- resting ECG and cardiac ultrasound to examine your cardiac structure and function-blood lab tests complete blood count, cardiac enzymes, inflammation tests, liver and kidney function tests, blood electrolytes. A fibrogastroscopy is necessary for the diagnosis. I would recommend starting omeprazole or lansoprazole. If your symptoms improve by these Chat Doctor. Hope to have been helpful! Kind regards,
