Hi, i am 25 years old, i really wanna know why my heart always pounding, i mean it beats really fast, whenever i woke up in the morning ang even after a nap on the afternoon.. when i was in college i also experience palpitations, but now i noticed that its happening almost everyday, as in every waking time. 2years ago i undergo ECG and 2D Echo, And the doctor said its normal. But until now its still like that and happens everyday. I think its not normal. Hope you can help me with this matter and would be very much appreciate your help. thank you Monica
