Which of the following technique is used to measure foetal heart rate?(a) ECG(b) FECG(c) PCG(d) VCGThe question was posed to me in semester exam.My doubt stems from Ambulatory Monitoring Instruments in chapter Arrhythmia and Ambulatory Monitoring Instruments of Biomedical Instrumentation

Answer»

Right option is (b) FECG

Explanation: Abdominal FECG processing CIRCUIT is used for computing foetal heart RATE. After proper placement of the electrodes, the SIGNALS are amplified in a preamplifier which PROVIDES a very high input impedance (100 MW) and high SENSITIVITY and good common mode rejection ratio (up to 120 dB).
