FIELD: medical engineering.
SUBSTANCE: method involves applying techniques for suppressing pregnant working electrocardiogram due to uniting all electrodes and sharply reducing her high-intensity high-amplitude electrocardiogram potential with low-amplitude electrocardiogram of the fetus being kept practically unchanged. The fetus electrocardiogram is recorded by several channels with broad coverage of zone under recording. Recording process is carried out from pregnant woman abdomen surface in non-invasive manner.
EFFECT: high accuracy of recording; removed noise; higher discretization frequency; suppressed high-voltage artifacts.
