170 is a little higher than normal at 13 weeks of pregnancy but you may have had a raised pulse yourself because of infection or nervousness. Actually this is not true. It is very normal for the baby's heartbeat to be in the 170's this early in your pregnancy. My research shows that several people have even had their baby's heartbeat in the 180's in the early stages, and had normal healthy pregnancies and baby's. "Normal" is 140-160, however Doctors have found 170 - 180's to be normal too.

An arrhythmia is an irregular heartbeat, which divides into two categories - tachycardia in which an adult's heartbeat averages above 100 beats per minute, and bradycardia - in which an adult's heartbeat averages below 60 beats per minute.
