Cardiovascular Flashcards
1
Q
S1
A
- Lub
- Closure of AV (mitral, tricuspid) valves
- Loudest at APEX of heart
- Marks end of diastole, beginning of systole
2
Q
S2
A
- Dub
- Caused by closure of semilunar valves (aortic, pulmonic)
- Loudest at base
- End of systole, beginning of diastole
- Splits on inspiration
- Wide fixed split caused by RBBB
- S2 louder with PE
3
Q
Aortic Value Ascultation Point
A
2nd Intercostal space, R sternal boarder
4
Q
Pulmonic Valve Auscultation Point
A
2nd Intercostal Space, L Sternal Border
5
Q
Tricuspid Auscultation Area
A
Fifth intercostal space, L sternal boarder
6
Q
Mitral/Apical Auscultation point
A
5th intercostal space, midclavicular
7
Q
S3
A
- Rapid rush of blood into dilated ventricle
- occurs early in diastole
- Apex, using bell
- HF, heard before crackles
- Ventricular gallop, “kentucky”
8
Q
S3 - Additional Causes
A
- Pulm HTN
- Cor pulmonale
- Mitral, aortic, tricuspid insufficiency
9
Q
S4
A
- Atrial contraction of blood into noncompliant ventricle
- Occurs before S1
- Apex with bell
- Atrial gallop “tennessee”
10
Q
S4 Causes
A
- MI
- Infarction
- HTN
- Ventricular hypertrophy
- Aortic Stenosis
11
Q
Pericardial Friction Rub
A
- Pericarditis
- Deep pain on inspiration
- May be positional
12
Q
Pulse Pressure
A
=Systolic-diastolic
13
Q
Normal Pulse Pressure
A
40-60 mmHg
14
Q
Narrow Pulse Pressure
A
- Drop in Cardiac Output
- Severe Hypovolemia
15
Q
Widened Pulse Pressure
A
- Decrease in SVR (systemic vascular resistance)
- Vasodilation
- Sepsis
