Define bradycardia. - CORRECT ANSWER: A heart rate that is:
- slow for normal range
- activity
- clinical condition
For stable patients with regular wide-complex, and monomorphic tachycardia, consider -
CORRECT ANSWER: adenosine
How are tachycardia and tachyarrhythmias classified? - CORRECT ANSWER: By the
width of the QRS complex.
How is tachycardia defined? - CORRECT ANSWER: A heart rate that is fast for the
child's age.
How should sinus tachycardia be treated? - CORRECT ANSWER: Treat the underlying
cause.
If amiodarone or procainamide does not terminate the rapid rhythm, why should
adenosine be considered? - CORRECT ANSWER: A wide-complex tachycardia could
be SVT with aberrant ventricular conduction.
If bradycardia persists after initial treatment, and HR < 60 /min, what is the next step? -
CORRECT ANSWER: Begin CPR.
, In what conditions is atropine preferred over epinephrine as 1st choice treatment of
symptomatic bradycardia? - CORRECT ANSWER: When the bradycardia is due to:
- excessive vagal tone
- cholinergic drug toxicity, e.g. organophosphates
- complete AV block (primary bradycardia)
In what patients would asymptomatic bradycardia not be problematic? - CORRECT
ANSWER: A well-conditioned athlete.
A healthy child who is sleeping.
Oxygen should be titrated to maintain a pulse ox saturation of - CORRECT ANSWER:
94-99%
Venticular fibrillation is associated with - CORRECT ANSWER: no organized heart
rhythm and no coordinated contractions.
What are characteristics of ventricular tachycardia? - CORRECT ANSWER: The rapid
rate may
- deteriorate into pulseless VT or VFib
- compromise ventricular filling
It is a wide QRS generated within the ventricles
What are the causes of primary bradycardia? - CORRECT ANSWER: Congenital or
acquired heart conditions.
What are the causes of secondary bradycardia? - CORRECT ANSWER: Hypoxia,
hypotension, hypothermia, acidosis, drugs.
What are the characteristics of atrial flutter? - CORRECT ANSWER: - Atrial rate 300
/min or higher
- Venticular rate often slower
