A fetus's heart rate is between 130-145 beats per minute. an embryo does not have a heart beat. once a growing person has a heartbeat it is considered a fetus.

The heart rate actually fluctuates throughout the pregnancy. The heart usually starts to beat about five weeks into the pregnancy at a rate of 75-80 beats per minute. It then quickens and reaches 165-185 around the 9th week. It then starts to decline, hitting about 150 around week 15 and maintaining around 145 until the fetus is full term.

A normal heart rate for an embryo ranges from 110 to 180 beats per minute. It can vary depending on the time of day.

The number of beats depends on the size of the embryo; 2 mm: 75 beats per minute, 5 mm embryo: 100 beats per minute, 10 mm embryo: 120 beats per minute, 15 mm embryo: 130 beats per minute.

It is generally between 120 and 160 beats per minute. It can be a little more or a little less without being dangerous though.
