When is a fetal electrocardiography performed during pregnancy?

Fetal electrocardiography, or fetal ECG, is typically performed earlier in pregnancy, particularly around the 12th week. At this stage, the fetus has developed enough for certain non-invasive monitoring techniques to be effective. This is crucial because it allows for the assessment of the fetal heart rate and rhythm, providing valuable information about the fetus's health and well-being.

Monitoring during this period can help detect potential issues early on, making timely interventions possible if needed. It is important for healthcare providers to establish a baseline heart rate and recognize any irregularities that may suggest underlying conditions.

In contrast, the other time frames suggested do not align with the standard practice for when fetal ECG is typically initiated. Waiting until later weeks might delay important assessments and limit the opportunity for early management of any complications.
