You have not mentioned how you feel after taking antacids. Take at least 15 days of regular antacids and if you feel better than you don't have to worry about anything. It appears from your details that you are probably suffering from gastric acidity an as all the tests are normal it is less likely to be related to heart. Just need to ask you few more histories
