1 lut 2024 · 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 and S 2 heart sounds? Heart sounds ...
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.
S1 and S2 Heart Sounds: S1 ('lub') is the closure of mitral and tricuspid valves; S2 ('dub') is the closure of aortic and pulmonary valves, indicating normal heart function. S3 Heart Sound: Known as the 'ventricular gallop,' follows S2, often linked to heart failure or increased blood volume; considered normal in young or athletic individuals.

S1 and the 2nd heart sound (S2, a diastolic heart sound) are normal components of the cardiac cycle, the familiar “lub-dub” sounds. S1 occurs just after the beginning of systole and is predominantly due to mitral closure but may also include tricuspid closure components.
17 lip 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.
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.
