Hello, I have gone through your query. Thanks for using Chat Doctor. Yes there can be heart problem with normal blood pressure. If you had chest pain with Oxygen of 85% there are high chances of having heart problem. Acid reflux will never lead to low oxygen. You should get ECG and further work up for your symptoms best wishes Chat Doctor.
