I'm a student and was wondering if it's normal to hear a split S2 sound on newborns? Sometimes when I'm auscultating and counting, it seems to me like there is an occasional 3rd sound. I asked a floor nurse about it and she thought that possibly I was getting confused hearing the couplets (lub-dub) because the heart rate was so fast. My perception was that there was definitely a third sound.

its not uncommon for young children to have an S3 sound when they are normally healthy...I always heard murmurs as a swishing along with the s3 - my 6 year old has an s3 and the ped (and research I've done) says that its normal in healthy children and athletes...
My pediatrician told me the trick is to count by fours, tapping a finger on each group as if you were tapping your toes to music as you listen ... "ONE (two three four), TWO (two three four), THREE (two three four), FOUR (two three four), FIVE (two three four), SIX (two three four), SEVEN (two three four)..." then multiply by four (For example, that was 28 beats.) Even if it's very fast you can keep track that way.

Very helpful! I have a few younger (infant/toddler) patients that when their respirations start climbing due to their disease process so does their heart rate. Because of their underlying condition can't always trust the pulse ox number. It's not a substitute for an apical or even a brachial.

I am not a student but thought someone here might be able to help.
I find it hard to count a newborn's heart rate because it is so fast. I have seen sites for learning breath and heart sounds and wonder if there is one for counting newborn's HR. I'm sure there are hints on how to do it and am hoping for somewhere that I can count & see how accurate I am. Any other hints would be welcome.
