What's a way to distinguish between gastroesophageal reflux and cardiac problem symptoms?

Sometime difficult : Both can give you chest pain. In general gerd is associated with burning chest pain, acid/sour taste in your mouth, cough at night, burning abdominal pain with stomach. Ascad associated with pressure type chest pain worsening during activities, heart palpitations, shortness if breath. Esophageal spasm from gerd can give you pressure pain. Good history/physical, stress test, endoscopy.
