EKG analysis

Question 1

1st step in the 6 step method

Answer 1

identify and examine the P wave; is it upright? present before each QRS

Question 2

2nd step (6 step method)

Answer 2

measure the PR interval; should be between 0.12 - 0.20 seconds

Question 3

3rd step (6 step method)

Answer 3

measure the QRS; should be between 0.06 - 0.12 seconds

Question 4

4th step (6 step method)

Answer 4

identify rhythm; regular or irrgular?

Question 5

5th step (6 step method)

Answer 5

measure HR

Question 6

6th step (6 step method)

Answer 6

interpret strip

Question 7

each small box is equivalent to…

Answer 7

0.04 seconds

Question 8

each big box is equivalent to…

Answer 8

0.20 seconds

Question 9

big box methods for HR

Answer 9

count big boxes between 2 R’s then divide by 300

Question 10

counting R’s method for HR

Answer 10

count the R’s within a 6 second strip then multiply by 10

Question 11

what are the 6 tachyarrhythmias

Answer 11

sinus rhythm, SVT, A-Fib, A-flutter, VT, V-fib

Question 12

interventions for sinus brady

Answer 12

atropine bolus

Question 13

interventions for sinus tachy

Answer 13

vagal maneuvers, adenosine, beta blockers, CCBs, cardioversion, cath ablation

Question 14

interventions for 1st degree heart block

Answer 14

may resolve on own; may need pacemaker or bolus of atropine

Question 15

interventions for 2nd degree heart block type 1

Answer 15

pacemaker; bolus atropine

Question 16

interventions for 2nd degree heart block type 2

Answer 16

pacemaker

Question 17

interventions for 3rd degree heart block

Answer 17

pacemaker

Question 18

Interventions for PVC

Answer 18

amiodarone or beta blockers; treat underlying cause

Question 19

interventions for VT

Answer 19

antiarrhythmics, antitachycardial pacing, cardioversion, defibrillation

Question 20

interventions for V-fib

Answer 20

defribrillation, CPR, amiodarone or epinephrine

Question 21

interventions for asystole

Answer 21

CPR, defibrillation, IV access, epinephrine, amiodarone

Question 22

T/F: asystole is a shockable rhythm

Answer 22

False

Question 23

interventions for PAC

Answer 23

if infrequent none needed; treat underlying cause

Question 24

interventions for SVT

Answer 24

catheter ablation, vagal maneuvers, adenosine, CCBs, digoxin, cardioversion

Question 25

interventions for A-flutter

Answer 25

adenosine, vagal maneuvers

Question 26

interventions for A-fib

Answer 26

cardioversion, anticoagulants, antiarrhythmics, ablation

Question 27

2nd degree heart block type 1

Answer 27

PR interval gets gradually longer and longer until there is no proceeding complex after P wave

Question 28

2nd degree heart block type 2

Answer 28

some complexes are present after p wave

Question 29

3rd degree heart block

Answer 29

no atrial impulse is conducted through the AV node into ventricles; more p waves then complexes
