Patient's question:
Hello, how many days after pregnancy can a fetal heartbeat be seen with an ultrasound?Doctor's answer:
Hello, under normal circumstances, fetal heartbeat can be observed on vaginal ultrasound or abdominal ultrasound at 5-6 weeks of pregnancy. After 7-8 weeks of pregnancy, the ultrasound can clearly show the fetal heartbeat, and at this time, the heart rate and rhythm can be measured using M-mode ultrasound, with the heart size being approximately 2mm. If the ultrasound image clearly shows an embryo without a heartbeat, it often indicates embryonic death and inevitable miscarriage. However, if the ultrasound is performed too early, the absence of a germinal disc and heartbeat cannot be considered abnormal.
