I can feel my heartbeat raisinga on lying down specially after eating 2-3 hours.mostly while turning to other side . I can also feel it on night when lying down. I had ecg and echo and both were normal.i had attached it.   The thyroid test was also normal. I use raciper tabler as Dr told due to ulcer I feel not lying palpitations when I use it  but after a week again I have same problem.What to do next.is it due to anxiety.
