Where do you hear s1 and s2 best?

S1 can be best heard over the apex, using a stethoscope’s bell or diaphragm. The first heart sound is caused by turbulence created when the mitral and tricuspid values close. S1 and S2 heart sounds are often described as lub – dub.Click to see full answer. Also asked, where is s2 heart sound best heard?CLINICAL PEARL: A split S2 is best heard at the pulmonic valve listening post, as P2 is much softer than A2. Like the S1 heart sound, the S2 sound is described regarding splitting and intensity. S2 is physiologically split in about 90% of people.Secondly, what does s1 and s2 indicate and where on the chest Do you Auscultate these sounds? Correct placement of the stethoscope on the chest corresponds to the sound of cardiac valves closing. The heart has two main sounds: S1 and S2. The first heart sound (S1) occurs as the mitral and tricuspid valves (atrioventricular valves) close after blood enters the ventricles. This represents the start of systole. Subsequently, question is, how can you tell the difference between s1 and s2 heart sounds? The 1st heart sound, S1 (lub), marks the beginning of systole (end of systole). 1. Auscultate the heart at various sites. S1 S2 Just precedes carotid pulse Follows carotid pulse Louder at apex Louder at base Lower pitch and longer than S2 Higher pitch and shorter than S2 Because systole is shorter than diastole: Which heart sound is louder s1 or s2?In a normal heart S1 is louder than S2 in the apex, and S2 is louder than S1 in the base. Compare the sounds from apex to base of the heart. S1 is generated by closure of mitral and tricuspid valves and they are close to the apex of heart.
