M. Tanaka et al., A CASE OF FETAL BRADYCARDIA AND SINUSOID-LIKE FETAL HEART-RATE PATTERN ASSOCIATED WITH MATERNAL HYPOTHERMIA, Fetal diagnosis and therapy, 10(3), 1995, pp. 207-209
A 23-year-old pregnant woman presented with severe hypothermia (33.8 d
egrees C) as a complication of treatment for urosepsis, The baseline f
etal heart rate was 100 beats/min. Despite evidence of variability, a
'sinusoid-like' pattern was observed. However, the fetal heart rate gr
adually returned to normal after rewarming the patient. This suggests
that maternal hypothermia may induce fetal bradycardia and a 'sinusoid
-like' fetal heart rate pattern.
