[|AI|]  Hello! Thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms don't seem to be cardiac related. A gastroesophageal reflux or hiatal hernia could be the cause of this clinical situation. So it is necessary to perform a careful physical examination and some tests: - a resting ECG- a chest X-ray study - a fibrogastroscopy to examine your gastroesophageal junction-some blood lab tests (complete blood count, PCR, sedimentation rate, blood electrolytes, kidney and liver function tests) to exclude other causes. You should discuss with your attending physician on the above-mentioned issues. Hope to have been helpful! Best regards!
