1. Apparatus for generating an output signal indicative of the rate of fluctuation of a human fetal heart, comprising:
- (A) means for coupling an input electrocardiographic signal from a fetus-carrying female human to said apparatus;
(B) means for processing said electrocardiographic signal to produce a first electric signal indicative of the rate of fluctuation of the heart of said fetus;
(C) means for coupling an input mechanical cardiographical signal from said human to said apparatus;
(D) means for processing said mechanical cardiographical signal to produce a second electric signal indicative of the rate of fluctuation of the heart of said fetus; and
,(E) means for comparing said electric signals for choosing the better of the two signals to produce an output signal best indicative of said fetal heart rate.
