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 perinatal medicine.
