Question

AECG technique fails in those rare cases where the amniotic fluid fails to provide adequate electrical coupling from foetus to mother.

(a) True

(b) False

I got this question at a job interview.

My question is based upon Ambulatory Monitoring Instruments topic in portion Arrhythmia and Ambulatory Monitoring Instruments of Biomedical Instrumentation

Answer 1

Correct choice is (a) True

The explanation is: Clinical trials have shown that the AECG technique is usually effective in most cases except in those rare cases where the amniotic fluid fails to provide adequate electrical coupling from foetus to mother. However, during labour, the uterine and abdominal wall electromyogram signals tend to obliterate the FECG signal, making FHR counting quite difficult. At present, the abdominal FECG, therefore, does not seem to offer a practical reliable means of FHR monitoring during labour and delivery.
