|
v1-v3
|
|
|
rates/intervals in peds are usually ___
|
shorter than adults
|
|
|
many kids can have irregular benign rhythms because
|
they have an increased vagal tone
|
|
|
premature atrial contractions and pvc's are abnormal in children?
|
no not necessarily
|
|
|
PVCS are seens in ___% of children and ___% of teenagers and adult men
|
5-10
60% |
|
|
10% of pts with PVCs have
|
mitral valve prolapse
|
|
|
Pt presents with PVCs, first thing is to rule out...
|
hypertrophic cardiomyopathy
long qt right ventricular dysplasia |
|
|
any pt w/ PVCs and syncope or idiopathic seizures musttttt
|
have an ECG and QTc
|
|
|
Pt gets PVCs when he exercises... what's this mean
|
poor prognosis, better if they are suppressed by exercise
|
|
|
who's more likely to present with LVH falsely?
|
skinny people, less soft tissue between leads
|
|
|
differential dx for sinus tachy during sleep or rest?
|
CHF, fever, thyroid (usually hyperthyroidism), myocardial disease, shock
|
|
|
a wide QRS in kids is usually a _____ phenomenon
|
post-op
|
|
|
SVT is characterized by....
|
narrow QRS
rate 150-250 atrial p-wave often lost in t wave |
|
|
a child has SVT before 4 months versus a child who has an SVT after 5 yrs of age, whats the difference?
|
33% will have reoccurence, at the mena age of 8, if they are under 4 months, as opposed to 83% of those who had SVT over the age of 5
|
|
|
Whats a contraindication for a rectal exam on a child?
|
increase intracranial pressure
|
|
|
Pt comes in with primary atrial tachycardia, why/why not would you give them adenosine?
|
Not, because adenosine slows sinus heart rate and is used only for primary ventricular tachycarida
|
|
|
when would you give a pt synchronized electrical cardioversion
|
unstable child who's unresponsive to adenosine or ice
|
|
|
What would you never wanna give a child for SVT tx?

|
|
|
Describe/outline SVT for infants
|
IV adenosinde, diving reflex if no IV, IV Digoxin
|
|
|

|
IV adenosine and verapamil
|
|
|
In WPW, the best leads to see the widened QRS are...
|
lead I, V5 and 6
|
|
|
meds for WPW..
|
Digoxin- shortens refractory period for alternate pathway, slows conduction in AV node, increases ventricular response to a fib
Propanolol- slows conduction of AV node, tx of choice |
|
|

|
CCBs, lethal arrhythmias
|
|
|
Top reasons for an infants HR to drop
|
apnea
|
|
