This pass week I have had many heart palpitations & not sure why? I had heart surgery when I was 3 yrs old on arotic value,I have check ups with a heart Dr every few months but they don't find anything unusual I have had stress test & everything ok! Last time I was at hospital they said I had many pvcs & said I had SVT, & I had to wear heart monitor for 24 hrs? I usually don't have any other systoms with them but does scare me,I have an appt with heart Dr next month! Thanks!
