Cardiology Flashcards
Ultimately, heart failure is diagnosed ___.
We get the echo. . .
Ultimately, heart failure is diagnosed clinically, on the basis of history, exam, labs, and CXR.
We get the echo:
- To differentiate between HFpEF and HFrEF
- To assess for secondary heart failure (valve problems, structural disease)
ACLS loop
For drugs: Alternate between epinephrine and amiodarone, starting with epinephrine.
Dosing: Epinephrine 1 mg each bolus, amiodarone 300 mg first bolus, 150 mg second bolus.
Managing atrial fibrillation without RVR
Managing atrial fibrillation with RVR
Hallmark EKG finding of AVNRT
Narrow QRS complexes without p waves (just t waves!)
When to use synchronized cardioversion vs defibrillation
Both are used as first-line only when the patient is hypotensive
Synchronized: A. fib, A. flutter, or monomorphic VT with palpable pulse.
Defibrillation: Pulselss VT or polymorphic VT with palpable pulse.
Post-Rheumatic Fever secondary prophylaxis
For RF w/o carditis: 5y or until 21
For RF w/ carditis: 10y or until 21
For RF w/ carditis and permanent heart damage: 10y or until 40
For each, you pick whichever option is longer and prophylax with oral or IM penicillin.
Appropriate pharmacotherapy for MSSE endocarditis
6 weeks of IV nacfillin, rifampin and 2 weeks of IV gentamicin
Single most common cause of infective endocarditis in patients with damaged heart valves who do not have other risk factors (ex, IVDU)
Streptococcus viridans group (sanguinis, mitis, mutans, salivarius, angiosus)
Single most common cause of infective endocarditis in patients with native heart valves who do not have other risk factors (ex, IVDU)
S. aureus
Treatment of choice for HACEK group endocarditis
IV Ceftriaxone
Remember, HACEKs are all gram negative
