Is it early to do fetal heart monitoring at 32 weeks?

Most hospitals start fetal heart monitoring at 34 weeks of pregnancy, and some hospitals start fetal heart monitoring at 32 weeks of pregnancy. There is no essential difference. 32 weeks of fetal heart monitoring, sometimes false positive rate will be higher, because the fetal response is not so strong, sometimes fetal heart monitoring will be slightly flat. Diagnostic criteria and 34 weeks are also slightly different, 34 weeks is double fifteen standard, 32 weeks is double ten standard. Of course, in patients with a history of abnormalities, such as intrauterine death, fetal heart monitoring can be started earlier, sometimes even after 28 weeks of pregnancy. Therefore, there is no very clear rule on when fetal heart monitoring should be started. However, it is necessary to check regularly. This is the most reliable indicator of whether the fetus is suffering from intrauterine hypoxia.
