3 sie 2023 · This is called the second heart sound (S2) and it is best auscultated at the Erb’s point. This landmark is located on the left third intercostal space, parasternally, between the pulmonic and tricuspid areas.
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 · Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds — the more turbulent the blood flow, the more vibrations that get created.
3 sie 2023 · Heart sounds are most often described by the “lub-dub” sounds, which are the mitral and tricuspid valves closing (S1) during systole, followed by the closure of the aortic and pulmonary heart valves (S2) during diastole. S1 is best heard in the mitral area, and S2 is best heard at the left upper sternal border.
