Abstract: A Doppler fetal heartbeat measurement device and method of use for reliable, convenient and inexpensive detection of fetal heartbeat and measurement of its rate from seven to twelve weeks gestation. The device is a conventional, inexpensive Doppler base unit having an intravaginal probe. Use of the present invention eliminates the need for the expensive procedure of transvaginal ultrasonic imaging for early detection of fetal heartbeat in the event of complications (e.g. cramping, spotting, pain) or the observation of a uterine size that does not correlate to the date of the last menstrual period.
