Normal.
If the heartbeat is under 140, its a boy. If it over 140, its a girl!
Between 140 to 160 beats per minute.
A baby's heartbeat can range usually anywhere from 120-160 during your pregnancy. It can fluctuate constantly. The time that they can predict what the sex of the baby is in only when you are in labor and hooked up to the monitor to track the baby's heart rate. It is at this time that the lower numbers (under 140) are usually a boy, and the higher (over 140) are usually a girl.Sounds about right. Ours was 140 this week (32 weeks); we've been told two versions of an "old wives' tale": One says 140=boy and the other says 140=girl. Guess we'll have to wait until the birth!!I'm 32 weeks' and 5 days' pregnant with b/g twins; as of today, the girl was 143 beats per minute and the boy was 130. The doctor said both were in the normal range.
This usually causes the irregular heartbeat to be reset into a normal heartbeat.
Divide [meters] by 1,000 to get [kilometers].140 meters = (140/1,000) = 0.140 kilometers
its not really proven but I guess 140 and over is supposedly a girl under is a boy
Usually because its a Tuesday
140/2
"atrial fibrillation" is the irregular quivering action of the atria, which in turn, may cause "palpitations" (the awareness of an irregular heartbeat) and/or "tachycardia" (rapid heartbeat).
You check their pulse, usually at the wrist or at the neck
There is no way to determine the sex of an unborn child by the fetal heart rate that has been proven.
Males usually are heavier, and have a larger proportion of muscle mass, so they tend to be stronger. What you mean by heartbeat - I have no idea.
