Fetal cardiac activity in 6 weeks embryo

This 6 week old pregnancy came for ultrasound imaging to check for the viability of the embryo. Ultrasound imaging could barely visualize the embryo, due to maternal obesity. On zooming in on the embryo, we could visualize this embryo with a suggestion of cardiac activity.

A color Doppler ultrasound study of the embryo showed this:

Clearly, the embryonic cardiac activity is visualized as a blip of color on Color Doppler. This helped avoid a transvaginal ultrasound scan study.
Spectral Doppler trace of the embryonic heart further confirmed normal cardiac activity and heart rate in the early embryo (HR= 130 beats/minute).
