My son's was always around the 140 mark whereas this one is usually around the 170-180 mark. I think it's another boy though. I find out on Saturday, so will update then.
My mum told me that with one of my older brothers she kept being told he was a girl as he had a high heart rate, so it didn't work for her.
As for labour, my son's heart rate was really high. So high in the end that they nearly considered c-section and they checked his oxygen levels by taking a blood sample from the top of his head. Luckily it was within the normal range, so they then did an assisted delivery with forceps to get him out in a hurry.
