May enhance fMCG signal quality in practice; leaves open prospective clinical validation.
Band-pass filters of 1.0-100 Hz and 2.0-100 Hz optimize signal quality in both shielded and unshielded fetal magnetocardiography, with 1.0-100 Hz preferred for arrhythmic fetuses.
Comani et al. (2005) studied Fetal magnetocardiography (n=66). Band-pass filters (1.0-100 Hz and 2.0-100 Hz) vs. Other filter settings was evaluated on Fetal signal detection rates, signal-to-noise ratio (SNR), and signal-to-distortion ratio (SDR). Band-pass filters (1.0-100 Hz and 2.0-100 Hz) provided the best combinations of fetal signal detection rates, SNR, and SDR for both shielded and unshielded fetal magnetocardiography.
