What the difference in cardiac preset and abdominal preset when measure heart rate. I'm confuse because on my machine when chose HR measure , I measure systole to systole , I got > 400 bpm. If I follow your second sample HR drop to around 200 bpm. I don't understand why I need to skip one systole as second sample?

If you use the cardiac preset, you measure systole to systole. If you use any other mode, you need to measure 2 cycles and skip one systole. This is determined by the ultrasound machine algorithm. The best way to make sure you are doing the correct measurement is to practice it on the heart of the patient, which heart rate you know for sure (for example, an adult dog with a normal heart rate that you can verify with your stethoscope).

Are all babies born with a heart rate less than 200? or only when there is dystocic birth?

According to Correa et al., Vet Sci 2024, a study that looked at newborn puppies (link - pmc.ncbi.nlm.nih.gov/articles/PMC11125728/), naturally delivered (eutocic) babies have a heart rate closer to 200 bpm, whereas C-section-delivered babies generally have a lower heart rate at birth (around 160). This suggests that delivery method may influence the heart rate at birth, with eutocic delivery associated with a higher initial heart rate. However, even for eutocic deliveries, the average heart rate remains slightly below 200 bpm, indicating that not all babies are born with a heart rate over this threshold. In general, heart rates are higher in newborn kittens when compared with puppies.
