Cardiovascular Flashcards
left axis vs right axis deviation
L: upright QRS lea I, downward aVF
R: downward QRS lead I, upright aVF
LBBB vs RBBB
LBBB: wide QRS with no R wave V1, wide, tall R wave I, V5, V6
RBBB: wide QRS, RSR’ V1, Wide S wave I, V5, V6
R vs L atrial enlargement
R (P pulmonale): P wave lead II >2.5
L (P mitrale): P wave lead II >120msec
Incr JVP with inspiration
Kussmaul sign: RV infarct, ccardiac tamponade, tricuspid regurg, constrictive pericarditis
Holosystolic murmur that radiates to axilla
mitral regurg
Midsystolic or late systolic murmur with preceding click
mitral valve prolapse
early decrescendo diastolic murmur
aortic regurg
mid to late, low-pitched diastolic murmur
mitral stenosis
S3 vs S4 gallop
S3: dilated cardiomyopathy, mitral valve disease, can be normal
S4: hypertension, diastolic dysfxn, aortic stenosis
L sided vs R sided HF
L: dyspnea (basilar rales, pleural effusion, pulm edema, orthopnea)
R: fluid retention (JVD, hepatojug reflex, periph edema, hepatomegaly)
Tx pulm congestion (LMNOP)
Lasix Morphine Nitrates O2 Position
S4 gallop, pulm cong, normal heart size, LVH, normal EF; dx and tx
nonsystolic heart dysfxn
Tx: diuretics, bbl/ACEi/ARB/CCB for rate/BP ctrl
Digoxin NOT helpful
ECG shows nonspecific ST-T changes, low-voltage QRS, LBBB: dx and tx
dilated cardiomyopathy
Tx: ACEi/ARB/bbl
Avoid CCB
ICD if EF
Defn dyslipidemia, recommended screening
LDL >130 or HDL 35y, q5y
>20 with risk
Stage I vs Stage II HTN and tx
Stage I: 140-159/90-99
Thiazide (or ACEi, ARB, bbl, CCB)
Stage II: >160/>100
Two drug combo (thiazide + ACEI, ARB, Bbl or ccb)
Hypertension, hypokalemia, metabolic alkalosis: dx, workup, tx
Conn’s syndrome
Incr aldost, decr renin
Tx surgical removal
hypertensive urgency vs emergency, tx
Urgency: incr BP and sx, no end organ failure; tx oral meds (bbl, clonidine, ACEI), lower over 2448h
Emergench: signs end organ damage (AKI, papilledema, ECG change)
Tx IV meds (labetalol, nitroprusside, nicardipine), lower 25% over 2 hrs
hypotension, distant heart sounds, JVD: dx and tx
Beck triad, cardiac tamponade
Tx fluids, emergent pericardiocentesis
indications for tx of aortic aneurysm
abdominal: >5.5cm
Thoracic: >6cm
tearing/ripping pain of ant chest or back, asymmetric pulses or BPs, neuro deficit: dx, workup, tx
aortic dissection
CT angio
Ascending: emergent surgery
descending: can manage medically
