Flashcards in Cardiovascular Exam 3 Deck (50)
what is the leading cause of death in the US?
what is the window to get pts to cardiac cath lab?
why would you measure JVP?
suspect right atrial pressure increase
what is a symptom of LV heart failure?
what is a symptom of RV heart failure?
swelling, pitting edema
why do you have to palpate pulses?
make sure they have peripheral perfussion
what causes a bruit?
trubulence-stenosis or plaque
what is a murmur?
turbulence of blood flow through a valve
where may an aortic valve murmur radiate to?
what is a thrill?
vibration-associated with a murmur (high intensity)
what is a lift or heave?
the heart lifts because it is working so hard to try to get blood out
if PMI is more lateral or larger in diameter what could that mean?
left ventricular hypertrophy
where is the normal location of the PMI?
4th-5th interspace MCL (midclavicular line)
diameter <2.5 cm (2-3 finger width)
amplitude should be brisk tapping
what causes LVH?
increased total peripheral pressure (HTN)
if PMI is hard to find what would you do?
turn the pt to the left decubitus position to put the heart against the chest wall
if amplitude of PMI is bounding that could mean
it is hypertrophied
what could cause RVH?
pulmonary valvular stenosis
increased pulmonary arterial pressure
describe location and purpose of aortic area
Right 2nd ICS at SB
listen to aortic valve
describe locatino and purpose of pulmonic area
Left 2nd ICS at SB
listen to pulmonic valve
describe location and purpose of tricuspid area
Left lower SB (LLSB) at 3rd, 4th, 5th ICS
listen to tricuspid valve, presence of murmurs and abnormal heart sounds
describe location and purpose of mitral area
MCL at 5th ICS
listen to mitral valve and presence of abnormal sounds
why would you have pt in left lateral decubitus?
accentuate S3, S4 and mitral murmurs
why would you have pt in sitting position?
accentuate aortic murmurs
when might an S3 be normal?
pregnancy, athletes (volume overloaded)
what ocular finding is related to malignant hypertension and end organ damage?
when does S2 split without pathology?
what is wide splitting?
secondary to pulmonary stenosis (delayed closure of the P. valve)-blood travels slower through the valve
splitting persists throughout the respiratory cycle
-would also hear a systolic murmur at the pulmonic listening area
what is fixed splitting?
splitting that does not vary with respiration (not as wide as wide splitting)
-right ventricular failure (decrease in pressure)
what is reversed (paradoxical) splitting?
appears on expiration only
-left bundle branch block (diminished contraction = decreased pressure which causes aortic valve to close later)
