How To Beat Lightheadedness Born With A Rapid Heart Beat?

Born with a rapid heart beat? - how to beat lightheadedness

I am a man, almost 17 years. My mother told me that he was born with a rapid heartbeat. Now sometimes when I'm upset, mad, scared or nervous, I feel my heart beat faster. Sometimes I stop and breathe deeply several times to stop. Sometimes when this happens, the experience weak arms and legs, dizziness, and a lot of sweat on his hands. My question is: Should I worry about something worry about? I am now after 17 years of my life, live, go see a doctor and get checked out? I also sometimes wet their hands and feet, which could be because my heart beats fast?
