question: Hi Im 15 and Im a girl. A few months ago during a flu that Ive got my heart started beating really fast and continued for a day or two. Ive been told that its normal. But after that these episodes started coming back for no reason and sometimes I get cramps around the area of my heart for no reason as well. Just today my heart started beating fast and hard again and Ive checked my blood pressure but its fine. Right now Im a bit lightheaded/dizzy and Im starting to worry. I play basketball and practise regularly, but my normal heart rate is a bit high (84bpm)...is there anything wrong? Should I go to the doc?
