Should not yet alter fetal monitoring practice; hypothesis-generating for magnetocardiography in assessing gestational age.
Observational (n=64)
Fetal magnetocardiogram using DC-SQUID can successfully identify fetal QRS complexes independent of maternal cardiac activity, with spectral amplitudes correlating with gestational age.
P.A. ANNINOS P. ANASTASIADIS (1999) conducted an observational in Normal and uncomplicated pregnancies (n=64). Fetal magnetocardiogram (FMCG) using DC-SQUID was evaluated on Power spectral amplitude distribution in the frequency range between 2 and 3 Hz. Fetal magnetocardiogram using DC-SQUID identified fetal QRS complexes unaffected by maternal cardiac activity, with power spectral amplitudes (120-350 fT/Hz) directly related to gestational age.
