Cardiac Flashcards
Aortic regurgitation is heard where?
2nd ICS, R sternal border
S/S of RV infarct
JVD @ 45 degrees, increase CVP, hypotension, clear lungs, bradyarrthymias; ST elevation in V3r, V4r
What causes large, giant V-waves on PAOP?
Mitral insufficiency (regurg)
What leads show reciprocal changes in lateral wall in inferior MI?
I, aVL
What does the RCA supply blood to?
posterior papillary muscle
3 leads with ST elevation in inferior MI?
II, III, aVF
Inferior MI= what occlusion?
RCA
What causes changes in V3R and V4R leads?
RV infarct
What causes changes in leads V1-V4?
anterior LV MI, LAD occlusion
What causes changes in leads V5, V6, I, and aVL?
circumflex, lateral LV
What causes changes in leads V5 and V6?
low lateral LV
What causes changes in leads I and aVL?
high lateral LV
What causes changes in lead V1 and V2?
RCA, post LV
Name AV valves. Heard where?
Mitral/tricuspid; apex (midclavicular, 5th ICS)
Normal CI values
2.5-3.5
Normal SVR values
800-1200
You should avoid preload reducers in this patient population
Patients with RV infarct
IABP balloon deflation decreases what?
LV afterload
What murmur and arrhythmias are associated with anterior MI?
Systolic murmur (VSD, heard at sternal border, 5th ICS) and 2nd degree Type II, RBBB (ominous sign)
Monitor for these arrhythmias if you have ST elevation in leads II, III, aVF
bradyarrhythmias, 2nd degree Type I AV Block, 3rd AV block, SSS; RCA supplies papillary muscles= systolic murmur may develop d/t MVR or muscle rupture
Use these meds with caution in inferior MI
BB, Nitroglycerin
Which heart sound is louder with a PE?
S2
What causes S3 heart sounds?
rush of blood into dilated ventricle
What diseases cause S3 heart sounds? Where are they heard?
pulmonary htn, cor pulmonale, heart failure, valve insufficiency (not pulmonic valve); heard at apex
