1. CARDIOVASCULAR ASSESSMENT AND PHYSICAL EXAMINATION

2. 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.

3. Anatomy & Physiology Functions of the heart & CV system Pumps blood to tissues to supply O 2 & nutrients Pumps blood to tissues to supply O 2 & nutrients Remove CO2 & metabolic wastes Remove CO2 & metabolic wastes

4. PERICARDIUM / PERICARDIAL SAC Protects heart from trauma Protects heart from trauma Serous fluid lubricates and Serous fluid lubricates and prevents friction prevents friction Prevents heart from over filling Prevents heart from over filling Anatomy & Physiology

5. 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) RIGHT CORONARY ARTERY POSTERIORMARGINAL

6. CORONARY ARTERIES ( R) ARTERY ( L) ARTERY LAD CIRCUMFLEX

7. 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)

16. VITAL SIGNS BP HEART RATE RHYTHM RESPIRATORY RATE TEMPERATURE

17. 17 INSPECTION

18. 18 JUGULAR VEINS/ JUGULAR VENOUS PRESSURE RIGHT SIDE, HEAD TILTED TO L ADJUST ANGLE OF BED TO SEE PULSATION AT MIDNECK RECORD DISTANCE FROM R ATRIUM TO TOP OF PULSATION

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

22. 22

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

25. AUSCULTATION Diaphragm – medium and high frequency sounds Diaphragm – medium and high frequency sounds Bell – low frequency sounds Bell – low frequency sounds Normally hear closure of valve Normally hear closure of valve Sounds from left side of heart louder than equivalent sounds from right side of heart Sounds from left side of heart louder than equivalent sounds from right side of heart

26. AUSCULTATION S 1 – closure of mitral and tricuspid valves S 1 – closure of mitral and tricuspid valves S 2 – closure of aortic and pulmonic valves S 2 – closure of aortic and pulmonic valves S 1 systole S 2 diastole S 1 S 1 systole S 2 diastole S 1 Simultaneous palpation of carotid pulse can help in differentiating S 1 and S 2 Simultaneous palpation of carotid pulse can help in differentiating S 1 and S 2

27. FIRST AND SECOND HEART SOUNDS Aortic component (A 2 ) normally louder than pulmonic component (P 2 ) Aortic component (A 2 ) normally louder than pulmonic component (P 2 ) Mitral component (M 1 ) normally louder than tricuspid component (T 1 ) Mitral component (M 1 ) normally louder than tricuspid component (T 1 )
