1. Myocardium heart muscle that surrounds ventricles and atrium
Atria are thinner as they need to pump less strong
2. pericardium external layer that protects heart from injury/infection
3. endocardium 3 layered membrane that lines heart chambers
4. blockage of coro- heart attack or stroke
nary arteries can
lead to
5. heart failure increased pressure of cardiac overload
-pulm congestion
-inc amount of blood in pulm capillaries
6. Left sided heart dyspnea/SOB, pulmonary edema
failure
7. right sided heart blood back up in the periphery and will present with edema
failure
8. cardiomegaly abnormal enlargement of the heart due to over working to compensate for
decreased function
9. frequency high pitched or low pitched
10. what should you high pitched, normal sounds
use the di-
aphragm of a
stethoscope for
11. what should you low pitched, abnormal heart sounds, murmurs
use the bell of a
stethoscope for

12. intensity/loud- loud or soft
ness
13. duration short heart sounds, or silent periods
14. timing systole or diastole
15. carotid found in the neck. feel one at a time. S1 is felt
artery/pulse
16. what is the most pedal pulse
diminished pulse
in the aging adult
17. normal heart S1 and S2
sounds
18. S1 heart sound -occurs with closure of mitral and tricuspid valves (AV valve)
-"lub" sound
-loudest at apex (5th intercostal space at midclavicular line)
19. S2 heart sound -occurs with closure of aortic and pulmonic valves (semilunar valves)
-"dub" sound
-loudest at base of heart (2nd intercostal space)
20. abnormal heart S3 and S4 sounds, murmurs, and bruits
sounds
21. S3 heart sounds -not usually heard
-gallop sound
-indication of HF
-occurs with ventricular resistance of filling

22. S4 heart sounds -create vibrations
-can be heard right before S1 sound
-occurs at end of diastole when ventricles resist filling
23. murmurs -from turbulent blood flow
-heard directly over heart
-gentle blowing/swooshing sound
24. murmur loud- 1-3: no thrill
ness scale 4: feel thrill
5-6: feel and hear thrill
5: hear thrill through stethoscope
6: can hear thrill without stethoscope
25. timing of mur- early, middle, late, systole/diastole (S1/S2)
mur
26. murmur pitch high, medium, low
27. murmur pattern grows louder or softer
28. murmur quality musical, flowing, harsh
29. murmur location valve/space it is heard at
30. murmur radia- down with blood flow
tion
31. murmur posture disappear/enhance with different pos.
32. systolic murmur -heard in between S1 and S2
-Mitral/Tricuspid stenosis/regurgitation, mitral valve prolapse
33. diastolic murmur
