1. Review anatomy & physiology of the cardiovascular system.
2. Discuss relevant aspects of the patient history.
3. Describe physical assessment of cardiovascular status.
4. Review diagnostic procedures, tests and medications relative to the cardiovascular system.

Anatomy & Physiology
Functions of the heart & CV system
Pumps blood to tissues to supply O2
& nutrients
Remove CO2 & metabolic wastes

PERICARDIUM / PERICARDIAL SAC
Protects heart from trauma
Serous fluid lubricates and
prevents friction
Prevents heart from over filling

CORONARY ARTERIES
Right & Left arteries encircle the heart and supply blood to the myocardium during
ventricular relaxation( diastole)
LEFT MAIN CORONARY ARTERY
L ANTERIOR DESCENDING (LAD)
L CIRCUMFLEX (LCX)

CARDIAC LOAD
Preload = degree of myocardial fiber stretch
at the end of diastole and just before
contraction
Afterload = pressure against which
ventricles must eject blood. This pressure is
affected by systemic vascular resistance
(SVR)

INSPECTION (continued)
• Lips, nail beds
• Heart: apical impulse
point of maximal impulse
• Extremities: (edema, venous or arterial
insufficiency)

IMPULSES – FINGER PADS
THRILLS ( vibration palpated secondrary
to a murmur – turbulant blood flow through
a heart valve)
APICAL IMPULSE ( normally 5th ICS and
medial to mid- clavicular line)
Point of max impulse
Left lateral decubitus : position apical
impulse more easily palpable

AUSCULTATION
• Diaphragm – medium and high frequency
sounds
• Bell – low frequency sounds
• Normally hear closure of valve
• Sounds from left side of heart louder than
equivalent sounds from right side of heart
![Page 26: CARDIOVASCULAR ASSESSMENT AND PHYSICAL …](https://reader030.vdocuments.us/reader030/viewer/2022012416/6170d22e7644ec736b62fd5d/html5/thumbnails/26.jpg)
AUSCULTATION
• S1 – closure of mitral and tricuspid valves
• S2 – closure of aortic and pulmonic valves
• S1 systole S2 diastole S1
• Simultaneous palpation of carotid pulse can help in differentiating S1 and S2
![Page 27: CARDIOVASCULAR ASSESSMENT AND PHYSICAL …](https://reader030.vdocuments.us/reader030/viewer/2022012416/6170d22e7644ec736b62fd5d/html5/thumbnails/27.jpg)
FIRST AND SECOND HEART SOUNDS
• Aortic component (A2) normally louder than
pulmonic component (P2)
• Mitral component (M1) normally louder than
tricuspid component (T1)

DIAPHRAGM
• Right 2nd intercostal spaceAortic Area
• Left 2nd intercostal spacePulmonic Area
• Third intercostal spaceErb’s point
• Left lower sternal border Tricuspid area
• Apex – over apical impulseMitral area

BELL
• Left lower sternal border
• Apex
• Apex with patient in left lateral decubitus
position
• Light pressure only!
