  • S1. first sound after the longest pause btw pairs of beats; occurs at onset of systole when AV valves close; LUB; Loudest over apex at LLSB.
  • S2. Closure of aortic & pulmonic valves; DUB; loudest over base of heart @ LUSB.
  • Systole. is the period between S1 & S2.
  • Diastole.
  • S3.
  • S4.
  • Murmurs.
  • Systolic murmur.

What produces the heart sounds explain?

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.

Where do you hear heart sounds?

Auscultation locations S 1 and S 2 are higher pitched sounds that are best heard with the diaphragm. Abnormal heart sounds, such as S 3 and S 4, are best heard with the bell of the stethoscope. S 1 is typically louder at the tricuspid and mitral space, whereas S 2 is louder at the aortic and pulmonic space. Aortic.

What are the different types of heart sounds?

The main normal heart sounds are the S1 and the S2 heart sound. The S3 can be normal, at times, but may be pathologic. A S4 heart sound is almost always pathologic. Heart sounds can be described by their intensity, pitch, location, quality and timing in the cardiac cycle.
