Cardiovascular disorders Flashcards
What are the indications for cardioversion?
Indications for synchronized electrical cardioversion include the following:
–Supraventricular tachycardia
–Atrial fibrillation
–Atrial flutter
–Ventricular tachycardia
–Any patient with reentrant tachycardia with narrow or wide QRS complex who is unstable (eg, chest pain, pulmonary edema, hypotension)
Medscape
What are contraindications for cardioversion?
–Known digitalis toxicity–associated tachycardia
–Multifocal atrial tachycardia
–Patients with atrial fibrillation who are not anticoagulated should not undergo cardioversion without a TEE that can assess the presence of left atrial thrombus
Medscape
What are indications for defibrillation?
Indications for defibrillation include the following:
–Pulseless ventricular tachycardia (VT)
–Ventricular fibrillation (VF)
–Cardiac arrest due to or resulting in VF
Medscape
What are contraindications for defibrillation?
Awake, responsive patient
What is this?
Digitalis toxicity
What is this?
A: hypercalcemia
B: hypocalcemia
What is this?
Hyperkalemia
What is this?
Hypokalemia
What is this?
Wolff Parkinson White
What is this?
Pericarditis
–ST elevation with entire T wave above baseline
–IVDU
–fever
–valve vegetations seen on TTE
–septic emboli in lungs or brain seen on CT
–get blood cultures
Is this endocarditis, pericarditis, or myocarditis?
endocarditis
–audible rub
–pain worse supine, improves if sitting up leaning forward
–diffuse ST elevations seen on EKG
Is this endocarditis, pericarditis, or myocarditis?
pericarditis
–often follows URI
–need a biopsy to diagnose
–Echocardiogram documents cardiomegaly and contractile dysfunction
Is this endocarditis, pericarditis, or myocarditis?
myocarditis
What is the top bug that causes endocarditis?
S. aureus

After S. aureus, what is the most common bug in endocarditis for
–native valve
–prosthetic valve
Native valve: S. viridans
Prosthetic valve: S. epidermidis
purple book 6-12
What is the treatment regimen for infective endocarditis?
Acute, native valve: vanco
Subacute, native valve: ceftriaxone
Prosthetic valve: vanco + gent + ceph
