Ja. Crowe et al., SEQUENTIAL RECORDING OF THE ABDOMINAL FETAL ELECTROCARDIOGRAM AND MAGNETOCARDIOGRAM, Physiological measurement, 16(1), 1995, pp. 43-47
The aim of this study was to demonstrate the acquisition of both the f
etal magnetocardiogram (FMCG) and fetal electrocardiogram (FECG) from
the abdomen of the same subject. This contrasts with previous reported
studies which have generally recorded one or other of these signals b
ut not the two together. Both signals were successfully recorded and a
veraged to produce a typical complex, thus allowing their direct compa
rison.
