Measurement of the fetal heart at 14 weeks of pregnancy can be done by ultrasound Doppler, or obstetric ultrasound.
Fetal heart, the heartbeat of the fetus, is usually 110 to 160 beats per minute. However, the heart rate can be fast in early pregnancy. Primary heart tube beats can usually be seen on ultrasound at around 6 weeks of pregnancy. It can be measured by Doppler echocardiography above the pubic symphysis after 12 weeks of pregnancy. It can also be measured by obstetric ultrasound.
During pregnancy, you should have regular checkups, and you can start to monitor your own fetal movements from the 28th week of pregnancy. The pattern of fetal movements varies greatly among individuals, and pregnant women need to know the pattern of their own fetuses. Eat a healthy and light diet and keep your mood happy. If there is any discomfort, consult a doctor in time.
