Hello, I am now 25 years old. When I was 20, my doctor had advised me to do a 2D echo test in a substandard clinic and they saw a mild mitral valve prolapse. I was referred to a heart specialist, he ruled it out saying that it was impossible for me to have such problem. Although, sometimes I experience chest pain and shortness of breath. I had my ECG done and the results was Sinus Arrythmia, is the chest pain due to stress?
