Gender & heart rate!?

Guys I’m so excited I find out the gender of my baby Friday morning! I have a 2 year old son and his heart rate was 160 and then dropped to the 140s once I hit about 16 weeks. This baby had a heart rate of 160 in the beginning and 140 now lol do you guys believe that heart rate has anything to do with the gender?! I heard if it’s over 160 a girl? What was your baby’s heart rate & gender?!
