I kep getting this pain in my heart, i cant describe it, its almost like a sharp pulling feeling like a dull pain which makes my heart rate increase ALOT ita like severe palpitations where my heart is very fast, irregular and visible with alot of pvc s :( I get out of breath cometimes, slightly tingelly and most of the time i pass out due to it Im getting kind of worried about it now because I am a 15 year old girl, i am a gymnast so im fit and everything else but this has caused me to pass out during gymnastics alot of times before I dont know what the cause it. P.S I have noticed a heart murmur and I know there is heart problems in my family
