That link is to the symptoms of GERD you'll see both the ones we traditionally think of as GERD and the more subtle ones. Once cardiac is ruled out, your doctor may want to try you on a trial of reflux medication. If you get better on medications then the diagnosis will be confirmed. Keep up with your doctor so that you can get to the diagnosis you need.
