Computerized diagnosis of fetal heart rate.
Aims: Objective analysis and evaluation of fetal heart rate (FHR) with continuous, sleepless and
restless computer action. Methods: The first step was composed of HP 2100A minicomputer,
paper-tape puncher and reader for FHR, Teletype keyboard and printer, author?s own program
with BASIC interpreter. The second one was MT140 micro computerized simple FHR data
printer for single pregnant woman, then the 4th one was central-computerized time-sharing
parallel working computer for multiple deliveries, composed of expert system, artificial neural
network computer and FHR frequency spectrum analyzer to diagnose sinusoidal FHR and the
loss of variability, with rapid and direct pathologic FHR reporting system to attendant physician.
The 2nd to 4th ones were TOITU product. Results: FHR data were analyzed and printed FHR
continuously, the 4th one resulted significantly reduced perinatal mortality and the loss of
cerebral palsy, confirming the effect of direct reporting system. Conclusion: Computerized FHR
monitoring system is not only automatically analyze FHR changes, but also clinically improved
