How fast is it going? If you have a stethoscope or can get one, listen to his heart for ten seconds, and count the beats making sure to count every other one. Write it down and do it two more times in a minute, find the average of the three numbers, and multiply that number by 6. That will tell you how many beats per minute. Anything over 200 is cause for concern. If you put your hand on his chest, and it feels like a hum, that is also a sign that it's going too fast. It's really hard to count w/your hand. You can also count by the pulse on his wrist or neck if you can find it. I always had a hard time w/that one on Ki because she is wiggly. If you can't count it, but it feels really fast, you need to talk to the doctor. Fast heart rate is very serious if it's too fast. Kiwi was born w/WPW, a heart condition that made it beat too fast and a lot of times it goes undiagnosed and causes heart attacks in kids as young as 12.
