Cardiology Flashcards
mechanism of syncope
ONLY BRAINSTEM stroke can cause syncope (controls sleep/wake in brain)
exertional SOB: immigrant, pregnant
MS
treatment for pericarditis if pain persists after NSAID
prednisone
diagnostic test for valve rupture
echo
is pregnancy a contraindication to do balloon valvuloplasty in MS?
NO
if cardiac exam is ABNORMAL, possible causes could be?
structural heart disease:
- aortic or mitral stenosis
- HCM
- mitral valve prolapse (rare)
mechanism of increased MS symptoms in pregnancy
- 50% increase in plasma volume
- more volume = more pressure, backflow, and symptoms
- ADH levels higher
best INITIAL treatment for WPW
procainamide
MC complaint in MR
exertional dyspnea
mechanism of S4 gallop
atrial systole into a stiff or noncompliant left ventricle
possible causes of RESTRICTIVE cardiomyopathy
- sarcoidosis
- amyloidosis
- hemochromatosis
- cancer
- myocardial fibrosis
- glycogen storage diseases
CHF presentation
- SOB, especially on exertion, and…
- edema
- rales
- ascites
- jugular venous distention
- S3 gallop
- orthopnea (SOB when lying flat)
- paroxysmal nocturnal dyspnea (SOB attacks at night)
- fatigue
treatment for RIGHT ventricular infarction
fluid loading
decreases mortality in patients with
- EF 120ms
biventricular pacemaker
best INITIAL treatment for pericardial tamponade
pericardiocentesis
- exertional SOB
- S4 gallop
hypertrophic cardiomyopathy
PARADOXICAL splitting of S2 (P2 delayed) causes
- LBBB
- AS
- LVH
- HTN
benefit of using aspirin in ACS
instant effect of inhibiting platelets
what does EKG show in constrictive pericarditis?
low voltage
Hill’s sign
BP gradient much higher in LE’s
if etiology of syncope is STILL NOT clear
- tilt table test (to diagnose neurocardiogenic (vasovagal) syncope)
- EP testing
CXR findings for MS (mitral stenosis)
- straightening of left heart border
- elevation of left mainstem bronchus
moderate AS pressure gradient
30-70mmHg
BLS for VF
- continue CPR
- defibrillate (UNsynchronized cardioversion)
- IV epinephrine/vasopressin
- defibrillate (UNsynchronized cardioversion)
- IV amiodarone/lidocaine
- defibrillate (UNsynchronized cardioversion)
repeat CPR between each shock
