Holter Monitor

I just got the results from the doctor's about Makenzie's Holtor and Michelle said that the max heart rate was 144 and the min was 48 and that is when she is sleeping, and her average is 91. She had a few pauses, but there were 2 pauses that were 2 seconds or greater. Michelle said that is good for her. I am a little nervous because the last one before this one her max was 144 her min was 55 and her average was 102. But Michelle said it could be that she is growing. Still makes me nervous though. But Makenzie seems to be doing great with those numbers she is up and running around like a 4 year old does.
