"kentucky",s3 is -chy ; s4,s1,s2 is "tennesse",s4 is "tenn--".
to differentiate murmur, first identify it's systolic murmur or diastolic
murmur. When you ausculate heart, also press carotid pulse. If murmur after
pulsation, it is systolic. if murmur before pulsation, it is diastolic. then
you need identify it is aortic murmur or mitral valve murmur. Move your
stethscope, find the area where you heard murmur sound loudes | d********g
发帖数: 11948 | 5 As far as I know, S3 comes after S2 whereas S4 comes before S1. So the
sequence should be S4, S1, S2, S3.
S3 happens when blood volume gets overwhelmed within the ventricle.S4 refers
to the condition when blood fills the atria too fast. | m****x
