Condition specifically: whether within a preset range each Fetal Heart Rate value in designated time period is judged, if any one Fetal Heart Rate
Value within a preset range, then determines that the Fetal Heart Rate value meets preset condition；If any one Fetal Heart Rate value is not within a preset range,
Then determine that the Fetal Heart Rate value is unsatisfactory for preset condition.The preset range can be 30~240 beats/min, it is not limited here.
Assuming that correct the Fetal Heart Rate value at third time point, then the fetal rhythm at amendment third time point is corrected by linear interpolation
Rate value specifically: by the time point for meeting preset condition before third time point at a distance from third time point it is nearest
Time point was determined as the 4th time point, by the time point for meeting preset condition after third time point with third time point
Distance nearest time point be determined as the 5th time point, when according to the time value at the 4th time point, Fetal Heart Rate value and the 5th
Between time value, the Fetal Heart Rate value put establish linear function, determine according to the time value of the linear function and third time point
Three time points revised Fetal Heart Rate value.
It should be noted that can also by way of cubic spline difference to be unsatisfactory for the Fetal Heart Rate value of preset condition into
Row amendment, is not limited thereto.
