EKG analysis Flashcards
1st step in the 6 step method
identify and examine the P wave; is it upright? present before each QRS
2nd step (6 step method)
measure the PR interval; should be between 0.12 - 0.20 seconds
3rd step (6 step method)
measure the QRS; should be between 0.06 - 0.12 seconds
4th step (6 step method)
identify rhythm; regular or irrgular?
5th step (6 step method)
measure HR
6th step (6 step method)
interpret strip
each small box is equivalent to…
0.04 seconds
each big box is equivalent to…
0.20 seconds
big box methods for HR
count big boxes between 2 R’s then divide by 300
counting R’s method for HR
count the R’s within a 6 second strip then multiply by 10
what are the 6 tachyarrhythmias
sinus rhythm, SVT, A-Fib, A-flutter, VT, V-fib
interventions for sinus brady
atropine bolus
interventions for sinus tachy
vagal maneuvers, adenosine, beta blockers, CCBs, cardioversion, cath ablation
interventions for 1st degree heart block
may resolve on own; may need pacemaker or bolus of atropine
interventions for 2nd degree heart block type 1
pacemaker; bolus atropine
interventions for 2nd degree heart block type 2
pacemaker
interventions for 3rd degree heart block
pacemaker
Interventions for PVC
amiodarone or beta blockers; treat underlying cause
interventions for VT
antiarrhythmics, antitachycardial pacing, cardioversion, defibrillation
interventions for V-fib
defribrillation, CPR, amiodarone or epinephrine
interventions for asystole
CPR, defibrillation, IV access, epinephrine, amiodarone
T/F: asystole is a shockable rhythm
False
interventions for PAC
if infrequent none needed; treat underlying cause
interventions for SVT
catheter ablation, vagal maneuvers, adenosine, CCBs, digoxin, cardioversion
