Embryonic Heart Rate
In a 1996 study normal successful human gestations were defined by EHR criteria at different early embryonic (34-56 days GA, from last menstrual period) developmental stages (at the earliest stages when embryo length is difficult to measure gestational sac diameters are included). [1]
- Stage 9-10 2 mm embryo (gestational sac diameter of 20 mm) EHR at least 75 beats / minute
- Stage 11-12 5 mm embryo (gestational sac diameter of 30 mm) EHR at least 100 beats / minute
- Stage 16 10 mm embryo EHR at least 120 beats / minute
- Stage 18 15 mm embryo EHR at least 130 beats / minute
