How to Pronounce Fixed Split S2

Say it like this: FIKST SPLIT ES-TOO. The word "fixed" rhymes with "picked," "split" rhymes with "kit," and "S2" is pronounced by saying the letter S and then the number two. Put the stress on the first syllable: FIKST.

In this context, "fixed" means that something stays the same and does not change. It comes from the Latin word meaning "firmly placed" or "not moving." So a "fixed split" is a split that remains constant, rather than one that changes.

"Split" means to divide or separate into two parts. When doctors hear a "split S2," they are listening to the second heart sound that has divided into two distinct sounds instead of one single sound. Think of it like hearing two taps instead of one tap.

"S2" is short for "the second heart sound." The "S" stands for "sound" and the "2" means it is the second one your heart makes during each heartbeat. You can say it out loud as "S-two" or "the second sound."

Break it like this: FIKST (one syllable) / SPLIT (one syllable) / ES-TOO (two syllables). So altogether it is four syllables: FIKST-SPLIT-ES-TOO.

People sometimes stress the wrong syllable and say "fix-ED split" instead of "FIKST split." Remember to put the emphasis on the first part—FIKST—and say the whole thing a bit quickly, like you are describing something that is permanently split apart.

It means a permanent separation of the second heart sound into two distinct parts that you can hear when listening with a stethoscope. Unlike other types of heart sound splits that come and go with breathing, a fixed split S2 stays separated no matter when you listen during the breathing cycle.

A doctor might say: "On auscultation, the patient has a fixed split S2," meaning that when listening to the heart with a stethoscope, the second heart sound is divided into two parts that remain separated consistently.
