Opening snap (OS) is a high-pitched sound that is caused by rapid opening of the mitral or tricuspid valve following the aortic valve closing sound (S2). This may indicate narrowing (stenosis) of the mitral or tricuspid valve; the closer in time the OS is to S2, the more severe the stenosis.

Before you listen to heart sounds you must know how to use your stethoscope’s chest piece properly. Diaphragm: use for listening to HIGH PITCHED sounds like S1, S2, and aortic/pulmonic murmurs. Bell: use for listening to LOW PITCHED sounds like S3, S4, and mitral stenosis murmurs.
In healthy adults, there are two normal heart sounds, often described as a lub and a dub that occur in sequence with each heartbeat. These are the first heart sound (S 1) and second heart sound (S 2), produced by the closing of the atrioventricular valves and semilunar valves, respectively.
S3, with or without S4, is usual in significant systolic left ventricular dysfunction; S4 without S3 is usual in diastolic left ventricular dysfunction. A summation gallop occurs when S3 and S4 are present in a patient with tachycardia, which shortens diastole so that the 2 sounds merge.
Feb 1, 2024 · Heart Sounds S 1, S 2, S 3, & S 4. Heart sounds are brief sounds produced by the opening and closing of valves. Systolic heart sounds include the 1 st heart sound (S 1) and clicks. Diastolic heart sounds include the 2 nd, 3 rd, and 4 th heart sounds (S 2, S 3, and S 4), as well as knocks and snaps. Let's take a closer look at each: What are S 1 ...
Oct 24, 2022 · The S1 sound is a term for the first heart sound. Doctors may also refer to it as “lub.” Some people may have a loud S1 sound if they develop mitral stenosis or tachycardia.
Heart Sounds. When a stethoscope is placed on the chest over different regions of the heart, four basic heart sounds (S 1, S 2, S 3 and S 4) can be heard (listening to heart sounds is called cardiac auscultation).
Jul 17, 2023 · Examples of diastolic murmurs are aortic and pulmonic valve regurgitation (AR & PR), tricuspid and mitral valve stenosis (TS & MS), S3 sounds, and S4 sounds. Diastolic heart sounds are more clinically significant because all diastolic murmurs are pathologic, except for some S3.
Jan 17, 2023 · S2. The second heart sound, called S2, makes a “dub” sound caused by the closure of the semilunar (aortic and pulmonary) valves following ventricular systole. S2 is split because aortic valve closure occurs before pulmonary valve closure.
