GERD can certainly lead to these symptoms. A barium swallow and upper GI series can help with the diagnosis.
If GERD is not present, it may be worthwhile to further evaluate the heart - especially given the elevated blood pressure. An echocardiogram is a reasonable test to evaluate the heart structure.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
