Should I be worried?

Alyson

I am 16 and recently i have had these “spurts” of where my heart just begins to race and I lose my breathe. I could literally be sitting or standing and it just happens and last for about 10-15 minutes. Today while at work it happened, and my Apple Watch had read my heartbeat to be up to 185bpm! I go Thursday to see my gyno for my yearly. Should I be worried and should I mention this to him?
