- Primary Outcome Measures
Name Time Method As a registry study, we will use test equipment monitor 6X23 as well as pre- approval fetal heart rate monitor (monitor 138). We will correct 170 cases fetal and maternal measurement raw dates. Pregnancy women's gestation ages are from 20 weeks to before delivery. And we will create each gestation ages database.
- Secondary Outcome Measures
Name Time Method The new method via maternal abdominal wall fetal electrocardiogram signal is extracted from measured raw dates corrected by new corrected program. We will analysis these. We will exploratory evaluate whether it can be clinical indications as fetal electrocardiogram. If it can be clinical indications as fetal electrocardiogram, we propose fetal electrocardiogram reference value from obtained dates in this study.
