Hi, yesterday evening I felt that my heart was bumbing a bit fast and It felt it was bubbling air inside my heart,, so when I burp it feels like the air gets out of my heart. And today I haven't felt that way, but now when the evening came It started again to feel the same way.
I Have felt like this for 1-2 years ago, but in that time I did a ECG test, and results was fine.
Do you know what it could be?
