A method for ecg - identification of the fetus and the nut over a plurality of epochs

摘要

It is a method using a mother''s / fetal monitoring system for monitoring the physiological properties both of a nut (10) provided as well as of a fetus. The method is placed in a series of ecg - electrodes (18) by means of the abdomen (20) of the nut and receives ecg - input shafts forms over a plurality of separate channels. The method, the channels using a ica - algorithm (30), in order to provide a series of ica - output waveforms from (36) to produce. The ica - output waveforms from (36) are analyzed for each individual epoch, in order to determine which of the channels a maternal signal (46) or a fetal signal (42) contains. On the basis of the determination, which channel the fetal and of maternal signals, a further processing to the ica - continuous-time type (36) on the identified channel is carried out in order to physiological properties for the patient and to obtain the fetus. During the next epoch is the same processing so that the system the fetal and of maternal signals themselves can then identify when the fetal and of maternal signals from a channel on a different jumping.
