Uworld Flashcards
Paraneoplastic syndromes
- secreatory, watery diarrhea due to VIP-secreting tumors.
- carcinoid syndrome
- Gastroparesis due to autoimmune destruction of GI neurons caused by variety of tumors
Management of first degree AV block with normal QRS duration
no further evaluation
Management of first degree Av block and prolonged QRS duration
electrophysiology testing
Dobutamine
Beta 1 receptor agonist
Increases myocardial contractility
Recent MI, now shows up with acute limb ischemia. Next 3 steps
- Anticoagulation
- contact vascular surgeon
- Transthoracic echocardiography
What is Peri-infarction pericarditis? Treatment?
- Post MI early onset pericardidits (Dressler is late MI complication)
- supportive treatment
How is the diagnosis of amyloidosis confirmed
tissue biopsy (abdominal fat pad).
Name 3 drugs good for heart rate and left systolic dysfunction <40% ejection fraction
- metoproplol succinate
- Carvedilol
- bisoproplol
3 risk factors for aortic aneurysms
- large diameter
- rapid rate of expansion
- SMOKING (not htn)
Interrupt EKG reading
1. High-voltage QRS complexes
2 Lateral ST segment depression
3. Lateral T wave inversion
left ventricular hypertrophy
Risk factors for aortic dissection
- Hypertension
- Marfan
- Cocaine
Suspected diagnosis of aortic dissection in patients with hemodynamic instability and renal insufficiency, next step?
transesophageal echocardiogram
Pulsus parvus et tardus
Arterial pulse with decreased amplitude and delayed peak
Seen in aortic stenosis
Initial diagnostic study of choice for a hemodynamically stable patient with type A aortic dissection
CT angiogram
Congenital bicuspid aortic valve can turn into what murmur
aortic regurgitation
What murmur is beast heard
Sitting up, leaning forward, holding breath in full expiration
aortic regurgitation
Most common cause of aortic stenosis in elderly patients
degenerative calcification of aortic valve leaflets
What heart sound changes in aortic stenosis
soft second heart sound
Name situations where you’ll hear an S3
Chronic mitral regurgitation
Chronic aortic regurgitation
Heart failure
High cardiac output states (pregnancy or thyrotoxicosis)
CYP Inducers
BullShit CRAP GPS: Barbituates St. John's Wart Carbamazepine Rifampin Alcohol (chronic) Phenytoin Griseofulvin Phenobarbital Sulfonylureas
What position brings the enlarged left ventricle closer to the chest wall?
Left lateral decubitus position
Laboratory findings for atheroembolism (cholesterol crystal embolism)
eosinophilia
Location of cause: Atrial fibrillation
pulmonary veins
Location of cause: Atrial flutter
Tricuspid annulus
Location of cause: AV nodal reentry tachycardia
AV node
Next step for a patient with atrial fibrilation RVR and hemodynamically unstable
Immediate synchronized electrical cardioversion
When is immediate debfribrillation recommended
V. fib or pulseless ventricular tachycardia
Location of cause: atrioventricular reentrant tachycardia
accessory atrioventricular bypass tract
Reversible risk factors for premature atrial contractions? treatment for symptomatic treatment?
tobacco and alcohol
beta blockers
Treatment for beta blocker poisoning?
1st: fluids and atropine
2nd: glucagon
Why can you use Dobutamine for bradycardia but not beta blocker poisoning?
Dobutamine causes more vasodilation and worsen hypotension
First step in treatment for pulseless electrical activity?
fluids
Pulsus paradoxus
Cardiac tamponade
SBP decrease >10 mmHg with inspiration
When do you hear pulsus bisferiens
aortic regurgitation
What is seen on EKG for cardiac tamponade
electrical alternans: amplitudes of QRS complexes vary from beat to beat
Classification of classic angina
- Typical location (substernal)
- provoked by exercise or emotional stress
- relieved by rest or nitroglycerin
Valsalva
decreases preload
Abrupt standing
Decreases preload
Nitroglycercin administration
decrease preload
Sustained handgrip
increase afterload
