Answer»

The correct choice is (b) two

Easiest explanation: The foetal heart rate is COMPUTED from the foetal ECG by appropriately SHAPING the foetal QRS WAVE. The FOETUS heart rate is approximately twice that of the NORMAL adult ranging approximately from 110 to 180 bpm. The main problem in processing the foetal heart signals is the poor SNR.
