Hya hun ive got a heart murmur, same thing like an extra heartbeat or valve I cant remember, ive had about 50 ECG in my lifetime…lol they couldnt make their minds up if it was serious, I was told it wasnt and was discharged from further investigation in 2007, so I hope this is not a problem for me also as I know theyll here it on the ECG but ive never had any issues with it.
