Calcification, old men, CP, syncope or CHF, crescendo-decrescendo systolic murmur
Aortic stenosis –> replace w/ gradient >50mmHg
Ejection click –> harsh, mid-systolic C-D, radiates to carotids
Aortic stenosis
D/T Infection, infarct, dissection, blowing decrescendo, widened pulse pressure, bounding pulse, head bob

HOCM & systolic anterior motion (SAM) of mitral valve (valsalva dec VR)
CP worse w/ exertion, better w/ rest, nitrates
STEMI, Trops w/ NSTEMI, only w/ stress test –> Cath
Cath: 1 vessel = stent + plavix, 3+ or includes LAD = CABG
Internal mammary for LAD, saphenous for all other vessels
Suspect re-infarct after previous CABG + MI, what enzymes?
CK-MB and myglobin, trops will remain high
PCWP after CABG 0-3; >20
More IVFs; ventricular failure
T-wave inversion, new RBBB, RVH/strain, acute dyspnea, CP
PE

Terminate SVT
Adenosine
Narrow complex tach, no P or buried in QRS or inverted
SVT —> Vagal or Adenosine
Young women, tachy b/w 160-220, no heart diease, cold water immersion helps
PSVT = Inc AV node re-entry/conductivity –> vagal & adenosine slow conduction
Dig toxicity arrhythmia
Atrial tachy w/ AV block (150-250)
Narrow complex tachy, BP 60/30 tx?
DC cardioversion
Pulmonary disease arrhythmia
Multifocal atrial tachy
Wide complex tachy tx
Amiodarone or Lidocaine
Wide complex tachy + 2 fusion beats or AV dissociation
Sustained monomorphic VT —> IV amiodarone
Tx of AFIB in unstable pt (common after CABG)
DC cardioversion
1 ectopic foci for AFIB
Pulmonary veins
Tx PEA
Compressions —> Epi q 3-5min
Premature atrial beats next step?
Observation - d/t anxiety, caffeine, CHF, electrolytes (BMP)
AFIB/flutter drug
Digoxin
Tx symptomatic bradycardia
IV atropine —> TCP —> pacemaker
Pt w/ WPW and new onset AFIB tx?
Cardioversion or anti-arrhythmic Procainamide
New onset AFIB next step?
Check TSH
Bradycardia with wide QRS “sine-wave” pattern, hyperK tx?
Calcium gluconate (faster than Kayexelate)
Hyperthyroidism, thyroxine induced arrhythmia
Sinus tach, PSVT, Atrial Fib

Endocarditis —> TEE —> vanco
1st step in infective endocarditis
3 blood cultures –> antibiotics, imaging
Holosystolic murmur inc w/ inspiration, IVDU
Endocarditis –> Vanco
Retrosternal CP worse w/ inspiration, better leaning forward, PR depression, MI 2 weeks ago
Pericarditis = Dressler syndrome (following MI) –> NSAIDs
Causes of pericarditis
Viral, SLE, uremia
DOE, edema, ascities, pericardial knock, calcified pericardium, prominent x and y waves
