During which trimester is a fetal heart rate first detectable?

• A. Around 6 weeks of gestation
• B. Around 12 weeks of gestation
• C. Around 16 weeks of gestation
• D. Around 20 weeks of gestation

Answer: (A)

Fetal heart rate is first detectable around 6 weeks of gestation. At this early stage, a developing embryo's heart begins to form and can generate a heartbeat, which is often detectable via transvaginal ultrasound. This early detection is crucial, as it provides important information regarding the viability of the pregnancy and the initial development of the fetus. The ability to detect the fetal heart rate earlier than other gestational milestones highlights the rapid progression of fetal development in the first trimester, laying the groundwork for subsequent prenatal assessments and monitoring as the pregnancy advances.
