srg Flashcards
Peripheral ischemia after arterial catheterization
cholesterol embolism
all patients w/ 3rd degree AV block should get
pacemarker
LBBB
prolonged QRS, large, wide R wave in 1/V6; S wave in V1
RBBB
wide S in 1/V6; RsR’ in V1
Tx acute viral pericarditis; classic EKG finding
high dose NSAIDs –> low-dose colchicine or steroids; EKG is PR depression and diffuse ST segment elevations
classic EKG finding for digitalis toxicity; Tx for this condition
atrial tachycardia w/ variable block; Tx is digitoxin-specific Ab fragments
Findings and complications aortic dissection
widening mediastinum on CXR; variation >20mmHg right vs. left arm BPs; complications = acute ischemia, aortic regurg, cardiac tamponade
Most important determinant of survival in cardiac arrest
time to defibrillation
PCWP/CO/SVR in septic shock
low PCWP, low SVR, high CO
PCWP/CO/SVR in hypovolemic shock
low PCWP, low CO, high SVR
PCWP/CO/SVR in cardiogenic shock
high PCWP, low CO, high SVR
anteroseptal MI
ST elevation V1-V4
apical/lateral inarct is
ST elevation V4-V6
Posterior wall infarction
a/w inferior wall infarction; ST depression V1-V2
RV infarction
hypotension, elevated JVP, clear lung fields
