1 Introduction
Pregnancy can be one of the most exciting times in your life, filled with fun, hope, and
enjoyment. There is nothing more exciting than hearing your baby’s heart beat
The Topcom Sweetheart is a fetal doppler monitor.
It is a hand-held ultrasound transducer that uses the Doppler effect to detect the heart
beat of a fetus and provides an audible simulation of the heart beat.
It works by bouncing sound waves off of your baby’s heart. The motion that your baby’s
heart makes when it is beating changes the shape of these sound waves. The baby
doppler then picks up these changed sound waves and amplifies it, in the form of your
baby’s heartbeat.
Fetal dopplers are safe to use at home, without the help of a physician.
• Occasionally, the fetal heart can be heart after 10 to 12 weeks pregnancy.
• After 14 weeks, it should be audible 95% of the time.
• After 16 weeks, the fetal heart should be nearly always audible.
