My baby's heartbeat at 7 week ultrasound was 78 is this normal I'm so scared

I went to my ultrasound a couple of weeks ago and my baby's heart rate was 78 I'm wondering if this is normal because I read some things and it said it was way to low.. Did any of your baby's have a low heart rate but them still be healthy
