Dysrhythmias, Endocarditis, HF

Question 1

HR below 60 that causes symptoms of reduced perfusion

Answer 1

Bradycardia

Question 2

waveforms appear normal but HR less than 60

Answer 2

Sinus bradycardia

Question 3

HR btwn 40-60 w/ either inverted P waves before or after the QRS complex or absent P waves

Answer 3

Junctional rhythm

Question 4

elongating distance btwn P wave and QRS complex

Answer 4

Wenckebach HB

Question 5

presence of P waves w/o corresponding QRS complexes after each one

Answer 5

Mobitz type II HB

Question 6

regular P waves and regular QRS complexes that are not coordinated (HR usually less than 40)

Answer 6

3rd degree HB

Question 7

occurs when heart can no longer produce sufficient CO at normal filling pressure to meet metabolic demands (usually when l ventricular EF falls below 40%)

Answer 7

HF

Question 8

peripheral edema, hepatomegaly, increased JVD, nausea

Answer 8

symptoms of r sided HF

Question 9

SOB/dyspnea, S3 heart sounds, crackles, pulm edema

Answer 9

symptoms of l sided HF

Question 10

inflammation of the endocardium, especially cardiac valves

Answer 10

infective endocarditis

Question 11

tender subq nodules, often in the pulp of digits

Answer 11

oslers nodes

Question 12

non-tender erythematous, hemorrhagic, or pustular lesions often on the palms or soles

Answer 12

janeway lesions

Question 13

repeat q 3-5 min PRN for symptomatic bradycardia

do NOT give less than 0.5 mg/dose

unlikely to be useful for bradycardia d/t HB

unlikely to be effective after cardiac transplantation

Answer 13

0.5 mg Atropine

Question 14

stable narrow complex tachycardia

rapid IV push followed by 20 cc bolus, may cause transient heart block or asystole

6 mg then 12 mg dose if ineffective

Answer 14

Adenosine
