Fetal magnetocardiography (FMCG) was recorded for 20 min to investigate its clinical efficacy. The multichannel SQUID system (MC-6400, Hitachi-Hightechnologies, Japan), which covers a wide area of the torso of pregnant women was used for recording FMCG. We also used simple methods to relieve adverse problems in long-duration measurement for pregnant women in the supine position: (1) light 10-min walking before FMCG measurement to reduce fetal movement, (2) placing a soft cushion under the patient's back to relieve back pains and (3) bending the knees to avoid supine hypotensive syndrome. All these methods were useful in relieving adverse problems.
