Precordium area on anterior chest overlying the heart & great
vessels; immediately in front of heart
Pericardium tough, fibrous double-walled sac that surrounds &
protects heart; contains a few mL of serous
pericardial fluid; adherent to great vessels,
esophagus, sternum & pleura, is anchored to
diaphragm
Pericardial sac surrounds heart; contains pericardial fluid that
allows for smooth, friction-free movement of heart
Myocardium muscular middle wall of heart that does the
pumping
Endocardium layer of endothelial tissue that lines inner surface of
heart chambers & valves
Mediastinum area between the lungs containing the heart, aorta,
venae cavae, esophagus, and trachea in the middle
third of thoracic cage
, How heart sits in chest cavity - rotated so R side is ant. and L side is mostly post.
- Base: top, left sternal border 2nd ICS
- Apex: bottom, 5th ICS mid-clavicular
Artrioventricular valves - R: Tricuspid
- L: Mitral (Bicuspid)
- Open during filling (diastole)
- Closed during pumping (systole) to prevent
regurg. of blood into atria
Semilunar valves - R: Pulmonic
- L: Aortic
- between ventricles & arteries
- Open during pumping (systole)
Diastole ventricles relax & fill with blood; 2/3 of cardiac
cycle
Systole contraction; blood pumped from ventricles & fill
pulmonary and systemic arteries
Apical pulse - found at apex of heart, 5th ICS mid-clavicular line
on L side
- ask pt to exhale & hold, palpate with finger pad
Sequence of assessing heart 1. Inspect
2. Palpate
3. Percuss
4. Auscultate
