Possible Outcome
_
The above figure shows the expected result of direct electrocardiogram from the fetus head, and Doppler ultrasound signals from two transducers placed in different places on mother.
US1 and US2 is the doppler wave that is emitted to the abdomen. The Lower US envelopes is the Fetal heart rate.
