Question 1

Step 1 in the order of application approach to reading EKGs

Answer 1

Heart Rate

Question 2

Step 3 in the order of application approach to reading EKGs

Answer 2

P wave

Question 3

Step 4 in the order of application approach to reading EKGs

Answer 3

PR interval

Question 4

Step 5 in the order of application approach to reading EKGs

Answer 4

QRS complex

Question 5

The number of electrical impulses conducted through the myocardium in 60 seconds

Answer 5

Heart Rate

Question 6

The heart rate of less than 60BPM

Answer 6

Bradycardia

Question 7

Heart rate greater than 100BPM

Answer 7

Tachycardia

Question 8

irregular rhythms that occur in a pattern

Answer 8

Regularly Irregular

Question 9

intervals of only one or two R-Rs are uneven

Answer 9

Occasionally Irregular

Question 10

R-R intervals exhibit no similarity

Answer 10

Irregularly Irregular

Question 11

Step 1 in evaluating the P wave

Answer 11

Are the P waves present

Question 12

Step 2 in evaluating the P wave

Answer 12

Are the P was occurring regularly

Question 13

Step 3 in evaluating the P wave

Answer 13

Is there one P wave present for each QRS complex present

Question 14

Step 4 in evaluating the P wave

Answer 14

Are the P waves smooth, rounded, and upright ( positive ) in appearance, or are they inverted

Question 15

Step 5 in evaluating the P wave

Answer 15

Do all the P waves look similar

Question 16

measure the time intervals from the onset of atrial contraction to the onset of ventricular contraction

Answer 16

PR interval

Question 17

Three questions when evaluating PR intervals

Answer 17

1. are the PR intervals greater than 0.20 seconds
2. are PR intervals less than 0.12 seconds
3. are PR intervals constant across the EKG

Question 18

represents the depolarization ( or contraction ) of the ventricles

Answer 18

QRS Complex

Question 19

the first negative or download deflection of this large complex. It is a small wave that precedes the R wave. Often the Q wave is not seen

Answer 19

Q wave

Question 20

The first upward or positive deflection following the P wave. In chest Lead II the R wave is the tallest waveform noted

Answer 20

R wave

Question 21

The sharp, negative ( or downward) deflection that follow the R wave

Answer 21

S wave

Question 22

above the ventricles

Answer 22

Superventricular

Question 23

begins with the end of the QRS complex and ends with the onset of the T wave

Answer 23

ST segment

Question 24

the point where the QRS complex meets the ST Segment

Answer 24

J point

Question 25

produced by ventricular repolarization or relaxation

Answer 25

T wave

Question 26

waveforms form sources outside the heart

Answer 26

Artifact

Question 27

Four common causes of artifact

Answer 27

1. Patient Movement
2. Loose or Defective Electrodes
3. Improper Grounding
4. Faulty EKG Apparatus
