When I was at rest for almost like an hour/s, sitting while painting a poster, I felt sharp pain on my chest but was inconsistently transferring on different parts of my chest area. Last June 24 I had a breathing problem and little palpitations (but not as always) so I went to a pedia-cardiologist for a check up. Then the doctor gave two tests, 2D Echo and ECG test. The results, in my ECG test it said that I have sinus arrhythmia which is normal, while on the 2D echo test, a PFO or a whole in the chambers of the heart was found, the doctor said there's nothing to worry about so I went home without any medicines, just a tailored diet. This august I felt that chest pain which I can't really understand (though I did not ate anything that would gave me an acid reflux) Does someone know about this situation?
