Heartburn /Gerd or something else???

Hello, Just wondering if anyone has experienced what i have had. I have acid reflux on and off, sometime i feel like someone is sitting on my chest and i cant get oxygen and sometimes i feel a flutter in my chest as if my heart stopped for a split second. It winds me. (Hard to explain). I have done heart test and all is good but because of these symptoms i second guess my dr. Anyone experience this at all???
