Hey, basicly over the last couple of months i will be sitting in my bedroom and all of a sudden my heart will beat out of pace like randomly and not in rythem and really hard which causes me not being able to breath, it lastes around 20 seconds but they seem to be getting worser, im only 16 years old is this normal?
This is not normal at all. High beating heart at times if not controlled can cause breathlessness, chest pain, coughing, dizziness, low blood pressure, and may cause heart block too. You need to consult the cardiologist for the same. If the EKG comes normal you need to go for electrophysiology study too. Moreover get 2D Echo of the heart to see for valvular problem.
