Heart Sounds (S.G) Flashcards
Auscultation areas of the heart acronym
All People Enjoy Time Magazine
A: Aortic location
2nd R ICS
P: Pulmonic location
2nd L ICS
E: Erb’s point
3rd L ICS
T: Tricuspid
4th/5th L ICS
M: Mitral (apex)
5th MCL ICS
Apex also known as
PMI-point of maximal impulse
S1 valve occurance
CLOSURE of AV valves (mitral & tricuspid)
S1 sound
“lubb” contraction of systole
Where is S1 heard the loudest?
Apex of heart
S2 valve occurance
CLOSURE of SEMILUNAR valves (aortic & pulmonic)
S2 sound
“dubb” relaxation diastole
Where is S2 heard the loudest?
base of the heart
S3 pathophys.
Rapid ventricular filling
S3 sound association
- ken-tu-cky
- heart fai-lure
S3 dz assoc.
heart failure
S4 pathophys.
Late diastole
S4 sound assoc.
- ten-nne-see
- Hy-per-ten-sion
S4 dz. assoc.
HTN
Where are Heart murmurs heard best?
apex of the heart
Causes of heart murmurs: SPAMS
S: stenosis of valves P: Partial obstructions A: Aneurysms M: Mitral regurgitation S: Septal defects
Two types of heart murmurs
- Systolic
2. Diastolic
Heart murmur descriptive characteristics
- timing
- duration
- pitch/intensity (1-6 scale)
- Pattern
- quality
- radiation
- respiratory variation
heart murmurs: Respiratory variation-
what if problem is on the RIGHT side of the heart?
INCREASE in intensity upon INSPIRATION
heart murmurs: Respiratory variation-
what if problem is on the LEFT side of the heart?
intensity DECREASES or REMAINS THE SAME
