Stomach or heart: Valvular heart disease, although possible, is less likely unless other symptoms appear. Seems most cardiac tests have been done to rule in heart problems. To evaluate for valve problems, one would check an echocardiogram (ultrasound of your heart). Are you compliant with your GERD medications? If so, speak with your gastroenterologist for alternative therapy or even titration of your current meds
