Purpose. Heart rates in embryos (6-8 weeks' gestation) have rarely been studied. We attempted to identify embryonic heart rates at 4 stages during 6-8 weeks' gestation and to relate our findings to fetal outcome at the end of the first trimester. We also tried to determine the lower limit of the hea
The greatest length (GL) and the crown-rump (C-R) length were compared in 43 staged human embryos. It was found that point C, which overlies the middle of the midbrain, was sometimes difficult to locate and that point R is not precise. These disadvantages render the C-R measurement unsatisfactory. A
