Cardiovascular Flashcards
Where does the heart sit in the chest?
2nd to 5th ICS, from the rt. sternal boarder to left midclavicular line
precordium vs pericardium
precordium: the region or the thorax immediately in front of the heart.
pericardium: fibrous sac surrounding the heart
AV valves/ SL valves: what do they seperate
right and left
AV: seperate the atria and ventricles right: tricuspid left: mitral SL: seperate ventricles and the great vessels right: pulmonic left: aortic
There are no valuves between pulmonary veins and the LA. As a result what can left sided heart failure lead to
There are no valuves between the vena cava and the RA. As a result what can right sided heart failure lead to
left: blood backs up into the pulmonary system and the lungs
right: blood backed up into the systemic system
Systole venticular contraction
1/3 of the cardiac cycle
- SL valves open so ventrilces can eject blood into the great vessels (systemic/ pulmonary)
- AV valves close to prevent back flow into the ateria, creates a “LUB” sound= S1
Diasotle ventricular relaxation
2/3 of the cardiac cycle
- AV valves open to allow for ventricular filling
- SL valves close so ventrilces so blood does not pass into the great vessels (systemic/ pulmonary), creates a “DUB” sound= S2
Palpation and auscultation of the carotid arteries
what are you feeling for?
wghat are you listening for?
strength (0-3+) and presence of a thrill (vibration)= turbulant blood flow
Use bell, presence of bruits= atherosclerosis= stinosis= increased risk of CVA
Jugular Vein Assessment APPI position abnormal normal
- Inspection only because you cannot palpate veins well
- pt. supine w/o pillow, using pen light
- Semi-fowler’s (45degree), If visable then + for JVD:
- bilateral= Rt sided HF, unilateral= local kinking or aneurysm
- Normal= cannot see
Inspection and palpation of the Precordium
Inspect for pulsations (lifts and heaves), apical impulse (PMI) at the 5th ICS, just medial to MCL
Palpate PMI: have pt. exhale then hold breath, can have pt. lean forward or roll to the left.
Thrill should be absent
FVO
fluid volume overload
Auscultation
Pt. with HF
S1/S2
use the diaphrgam listen for rate and rhythm
Listen at the apex for those with HF, DO NOT use the radial pulse
S1 is louder at the apex (b/c AV valves are closing)
S2 is louder at the base (b/c SL valves are closing)
APETM "LUB": Aortic: 2nd ICS Rt sternal border Pulmonic: 2nd ICS Lft " " "DUB": Erb's Point: 3rd ICS Left sternal border Tricuspid: 4th ICS " " " Mitral: 5th ICS Lft MCL (apex)
Follow up with the bell to hear and extra heart sounds.
Have pt. lay on their Lft side to listen for S3 and S4 at teh apex
S3:
what it is/ when it occures
patho
phys
S4:
what it is/ when it occures
patho
phys
Using the bell, at the apex, vibrations within left ventrical filling
S3= ventrical gallop, early diastolic sound (right after DUB), assoc. with rapid filling (splashing) in an overaly compliant LV
Pathologic: systolic HF
Physiologic: children, athletic adults <35 yo, during pregnancy
S4= atrial gallop, late diastolic sound (right before LUB), assoc. with fluid kickback in a hypertorphied LV.
Pathologic: diastolic dysfunction (poorly compliant LV when filling)
Physiologic: older adults after exercise
Murmurs:
functional
innocent
patho
what to document
functional: caused by increased SV and CO (fever, pregnancy, hyperthyroidism)
innocent: heard when there is no patho cause
patho: murmur due to valvular disease (regurg/ stinosis)
what to document: timing- systole (poss. normal), diastole (patho) location- APETM quality- musical, blowing, rumbeling pitch- high, med, low pattern- crescendo/ decrescendo loudness- 1-6 scale posture: enhanced or diminished with change in position
crescendo
decrescendo
crescendo—decrescendo murmurs
Crescendo murmurs progressively increase in intensity.
Decrescendo murmurs progressively decrease in intensity.
With crescendo—decrescendo murmurs, a progressive increase in intensity is followed by a progressive decrease in intensity.
Splitting
normal
abnormal
heard with diaphragm
normal if occures only during inspiration ONLY due to delayed tricuspid (S1, at apex, end of diastole)/ pulmonic (S2, at base, early diastole) closure
Abnormal if split is wide, paradoxical or fixed
