Cardio Rosh Flashcards
MCC Vfib
severe ischemic cardiac disease
does hyperkalemia or hypokalemia cause Vfib
hyperkalemia
Tx Vfib
chest compressions and administration of epinephrine 1 mg IV every 3–5 minutes
chest compressions 100-120/min
in SVT, if vagal maneuvers are ineffective, what tx should you do next
Adenosine 6 mg then 12 mg
In what patient population should you use adenosine with extreme caution?
Those with heart transplants due to prolonged drug effect.
Nontraumatic causes of cardiac tamponade include
malignancy, acute pericarditis, uremia, bacterial pericarditis, chronic pericarditis, spontaneous hemorrhage, systemic lupus, post-radiation, and myxedema.
PE for cardiac tamponade
tachycardia
low systolic blood pressure
narrow pulse pressure
JVD
distant heart sounds
hypotension
tx for pericardial effusion / tamponade
The initial treatment should involve volume expansion with a 500–1,000 mL fluid bolus. However, this is only a temporizing measure, and pericardiocentesis is necessary for definitive therapy. In the setting of hemodynamic instability, pericardiocentesis should be performed in the emergency department
What is the most common cause of atraumatic pericardial effusion with tamponade?
malignancy
CXR for HF
cardiomegaly
Kerley B lines
pulmonary venous congestion
pulmonary edema
Interstitial perihilar infiltrates, also known as “bat winging,
Pleural effusions, typically right-sided
What causes Kerley B lines on chest X-ray?
engorgement of lymphatic vessels
A hypertensive emergency is defined as
systolic > 180 mm Hg or diastolic > 120 mm Hg with concomitant end-organ damage
Examples of hypertensive emergencies include
acute aortic dissection, acute pulmonary edema, acute myocardial infarction, acute coronary syndrome, acute kidney injury, severe preeclampsia or eclampsia, hypertensive retinopathy, hypertensive encephalopathy, subarachnoid hemorrhage, intracranial hemorrhage, acute ischemic stroke, or a sympathetic crisis
initial antihypertensive of choice for patients presenting with aortic dissection
esmolol
add nicardipine if needed
