Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that your symptoms seem to be relate to gastro esophageal 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 drugs, the diagnosis of gastroesophageal reflux would be much probable. Hope to have been helpful! Kind regards, Dr. Iliri
