(26 cards)
HOCM murmur inc and dec
dec filling - inc murmur - valsalva, standing up – harsh mid systolic murmur at LLSB —- dec murmur, hand grip, trendelenburg, volume expansion
med to give in HOCM
b blocker, ca blocker s - neg inotropes
tx pericarditis
nsaids, colchicine
right sided diastolic collapse
pericardial tamponade
mcc viral myocarditis
parvo b 19 , cox b
sinus tach out of proportion to fever
myocarditis, signs of chf, enlarged heart, troponin
htn urgency guidelines
dbp >110, do not lower acutely in ED unless end organ dmg
tx aortic dissection
shear first - b blockers- esmolol- then nitropussure or nicardipine- prevent reflex tachy
tx htn in catchecholamine crisis- pheo cocaine maoi
oppoiste of aortic dissection- do not use b lbocker alone- upooposed constriction use labetalol plus phentolamine alpha blocker
stemi assn with dissection
Type a- RCA - inferior stemi
location of AAA
majority are infrarenal, mc missed diagnosis is renal colic, microscopic hematuria
older patient with abdominal or back pain
AAA and mesneteric ischemia
coplication of DVT
phlegmasia cerulea doelns - prevents obstrucion, stagnat blood- cyanotic and blue, bullae, compartment syndrome, or Phelgmasia alba dolens – pale doughy- causes arterial spasm
hypo/hyper ca effect one kg
hypo- proloooonged, hyper- shert
prolonged QT elecetrolytes
hypooo K hypoo ca hypooo mg
MAT
irregular irregular narrow complex, 3 diff p wave morphology- associated with hypoxia, copd, theopylline-
how to pace torasades
overdrive pacing - 120
what does magnet due to pacemaker
convernts from sensing to fixed rate
way to find WPW on ekg
short PR then look for delta
a fib with changing morphologies
WPW with A fib - do not use nodal blockers- (amio b bloc ca block) use procainamide or electicity
drug to treat stable v tach
procainamide, or amio
accelerated idoventricular rhythem
rate under 120 - assn AMI and reperfusion, - just observe - can also have in tox / OD like hyper K, TCA
2nd deg type 1 wenkebach
gradually inc PR then beat dropped (tx atropine if unstable)
2nd deg typ 2 mobitz II
constant wider PR then beat dropped (pace if unstable)
