Abstract:
Non stress test (NST) followed by a FAST using Coro metric model 146 \vas carried out in
486 subjects with uncomplicated singleton pregnancies and periods of gestation 32 weeks in
early labour. The response to FAST was assessed and compared with the NST. A repeat
NST was recorded in the subjects who had an initial non reactive NST. The results of the
NST and FAST were compared with fetal outcome. Maternal perception of fetal movements
