title: A sinusoidal-like fetal heart-rate pattern in association with fetal sucking--report of 2 cases.
abstract: A sinusoidal heart-rate pattern (SHR) is usually considered to signify fetal distress. Two cases are reported in which a sinusoidal-like fetal heart-rate pattern was caused by fetal sucking movements as observed by real-time ultrasonography. The patterns observed in these two fetuses were similar to that found in the neonate during suckling.
