Objectives
Narrative objectives1 For heart rate is one fetus of important items of fetal monitoring in perinatal care, the ultrasonic Doppler method is widely used, for the electrocardiographic measurement of the fetus, now, we measured the only expulsion just before It is only a direct induction method is possible. This method is adapted only during expulsion, since there is invasive to the fetus, required to grasp the ECG of the fetus by the accurate and simple measurement method as one of early fetal monitoring trimester or later It is.
This study, this is a new registry study the clinical application of a fetal electrocardiogram abdominal wall inductive method aimed, by analyzing the collected measured raw data to confirm the usefulness of the fetal electrocardiogram was further stored it is planned to consider the setting of the fetal electrocardiogram reference value from the fetal electrocardiogram data in Japan.
Thus, the present study are the registry studies aimed at collecting various data that assumes when it is marketed, by multilateral analysis of the collected data, type and frequency of arrhythmias in fetal , severity, and even transition such as these symptoms are associated with pregnancy course of the observed pregnant woman and the fetus is likely to be elucidated.
Fetal ECG heart rate monitor to be used in the new abdominal wall induction method, from Japan are expected as new medical equipment, and has been developing with a view to commercially available abroad as future development expansion, joint international clinical trial (trial ) it also considered.

Assessment
Primary outcomes 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.
Key secondary outcomes 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.
