Abstract
A HyperCard tool has been designed to support research on human fetal heart rate responses to extrauterine auditory and tactile stimuli. This system allows an operator to digitize a standard graphic heart rate strip recording simply by tracing it. In our application, the software produces a listing of fetal heart rate in beats per minute at 1-sec intervals and a variety of summary statistics, which can be saved on disk and printed. This tool has the advantages that it permits rapid and accurate manual scoring and allows for operator judgments concerning artifacts, a flexibility missing from automated systems. This tool can be generalized to allow scoring of any graphic strip recording.
