6) QRS interval
7) T wave
8) QT interval

Question 3

What wave doesn’t every CC or cardiac cycle have

Answer 3

Q wave

Question 4

Sinus rhythm consist of?

Answer 4

PQRST

Question 5

What do examine on the EKG strip for ventricular rhythms?

Answer 5

For ventricular rhythms examine R to R intervals

Question 6

For the atrial rhythm, observe the

Answer 6

P-P intervals and ask are they regular

Question 7

How do you determine the rate?

Answer 7

There are several methods we:
Count the number of QRS complexes over a 6 second interval
Multiply by 10 to determine heart rate

Question 8

Are heart rate and pulse the same

Answer 8

Yes

Question 9

Represents atrial depolarization

Answer 9

P Wave

Question 10

Atrial deplorarization means to

Answer 10

Means to contract

Question 11

In a normal EKG, the P-wave precedes

Answer 11

The QRS complex

Question 12

How does the P-wave look

Answer 12

Like a small bump upwards from the baseline

Question 13

P-wave begins until

Answer 13

The beginning of the QRS complex

Question 14

_____________Marked paper or counting small boxes method can be used to determine _______________

Calipers, PR intervals.

Question 15

The methods used to determine PR intervals is. Or ally this interval

Answer 15

0.12 to 0. 20 seconds (3-5 seconds)

Question 16

How do you count this interval 0.12 to 0.20 seconds

Answer 16

0.04 little box
x 5 reason why or how big wave is counted
__________
0.20 big box

Question 17

What complex indicates ventricular depolarization?

Answer 17

QRS

Question 18

The QRS complex indicates

Answer 18

Ventricular depolarization

Question 19

What does depolarization trigger?

Answer 19

Depolarization triggers contraction of the ventricles.

Question 20

What wave indicates repolarization?

Answer 20

T wave

Question 21

The T wave indicates

Answer 21

The repolarization of the ventricles

Question 22

The T waves is a

Answer 22

Slightly a symmetrical, wave form that follows after a pause, the QRS complex.

Question 23

Ventricles are starting to relax again when?

Answer 23

T-wave

Question 24

Represents the time of ventricular activity including both depolarization and repolarization.

Answer 24

QT

Question 25

Represents the early part of ventricular repolarization

Answer 25

The T segment
