Hello, I'm a 21 year old male. Recently I have felt like something is wrong with my heart. I feel palpitations and or skipping beats. Also, I kind of feel uncomfortable in my chest area sometimes. I've had the following tests done: chest x-ray, echo, blood tests, heart monitor, physical exams, and an EKG. The only thing they said that was wrong was sinus arrhythmia which was normal they said. I was wondering why I might feel like something is wrong with my heart and are these tests enough? Also, I have high stress and anxiety now that I feel something is wrong with my heart. Can stress and anxiety cause skipping beats and palpitations? Are these tests that I've had enough to say my heart is allright? Lastly, I'm always worrying about my heart now and my mind is always on it, so please help me!
