I am 28 and weigh about 135.  I am generally very healthy. Last nite I was walking up the stairs and my heart rate went out of control....I could see my heart beating through my chest.  I felt fine other then my high heart rate.  Today im experiencing horrible heart burn.  Can you give me an idea what this may be or if i need to see my doctor.
