Auscultation of Heart Sounds
1.The bell of the stethoscope is used to listen to frequency sounds.-
: lower
2.The diaphragm of the stethoscope is used to listen to frequency
sounds.: higher
3.Auscultation position for aortic valve?: right 2nd intercostal space
4.Auscultation position for the pulmonary valve?: L 2nd intercostal space
5.Auscultation position for the tricuspid valve?: left of sternum - 4th
intercostal space
6.Auscultation position for the mitral valve?: midclavicular line - 5th
intercostal space
7.How are heart sounds produced?: -valve opening and closing
-movement of bl in heart
8.more turbulent blood = audible sounds: more
9.What can you have the patient do to hear heart sounds better?: -bring
heart closer to chest wall by
1.left lateral recumbent position
2.upright, leaning forward position
10.What heart sounds are heard best with the diaphragm? S1, S2, S3, S4?:
S1, S2 (normal closing/opening of valves)
11.What heart sounds are heard best with the bell? S1, S2, S3, S4?: S3, S4
12.Does S1 or S2 coincide with the beginning of systole? Diastole?: S1 'lub'
- systole; S2 'dub' - diastole
13.What occurs with the valves and cx during S1 "lub"?: - Mitral and
tricuspid valves close
-aortic and pulmonic valves open
-start of systole and isovolumetric cx - QRS complex on ECG
14.What occurs with the valves and cx during S2 'dub'?: -aortic and
pulmonic valves close (aortic louder and before pulmonic due to higher
pressure)
-mitral and tricuspid valves open
-start of diastole and isovolumetric relaxation - just before the T-wave on
ECG
15.Explain the physiologic splitting of heart sounds (S2) during breathing: -
-expiration- A2 and P2 heart as one sound
-inspiration - delayed P2, so A2 closes first
--decreased intrathoracic pressure
--increased venous return and R ventricular volume compared to left
16.What auscultation location is the physiologic split best heard?:
pulmonic area with diaphragm - Left side 2nd intercostal space

17.What is occurs when you have pathologic splitting of S2?: Ventricle
takes TOO long to empty
