two months a go i started having an annoying dry cough and now have chest fullness like there is air and i belch a lot. at first i thought it was from wating but i do it even if i dont eat or drink anything. I feel palpitations like a heavy abnormal heartbeat and i hooked up to an ekg and when i feel full or air i have bigeminy and then belch and it feels better for about 30 seconds and then comes back.  cant lay on left side because i feel the same heartbeat feeling on that side. always have to lay on back or right side. goes on all day long. I am 44 about 150 pounds and no other history of anything.
