Question 0

Atrial kick - what is it and what does it look like on ekg?

Answer 0

Caused by atrial depolarization and manifests on the ekg as a P wave.

Question 1

Diastole - definition and stages

Answer 1

Ventricles fill and relax. Stages are
Rapid filling phase,
Diastasis
Atrial kick

Question 2

Systole - definition and stages?

Answer 2

Ventricles contract and eject their blood. Stages:
Isovolumetric contraction
Ventricular ejection
Protodiastole
Isovolumetric relaxation

Question 3

P wave

Answer 3

Atrial depolarization

Question 4

Normal P waves are:

Answer 4

Small, rounded, and upright.

Question 5

T wave

Answer 5

Atrial repolarization, normally not seen as it happens during QRS complex

Question 6

QRS complex

Answer 6

Ventricular repolarization

Question 7

A normal qrs complex

Answer 7

Is spiked in appearance, consisting of one or more deflections from the baseline. It’s shape can vary.

Question 8

T Wave

Answer 8

Represents ventricular repolarization.

Question 9

A normal T wave is:

Answer 9

Broad and round

Question 10

If there is a QRS complex, then:

Answer 10

There must be a T wave after it.

Question 11

U wave

Answer 11

Represents late depolarization, not normally seem, shallow and round deflects the same way as the T wave.

Question 12

Each P-QRS-T is

Answer 12

One heartbeat

Question 13

Each small block on the EKG paper measures

Answer 13

0.04 seconds

Question 14

Five small EKG blocks together are

Answer 14

One big block, 0.2 seconds

Question 15

25 small blocks on EKG paper are

Answer 15

1 second of time

Question 16

300 big blocks are

Answer 16

1 minute of time

Question 17

PR interval

Answer 17

0.12 to 0.20 seconds (includes p wave and pr segment)

Question 18

QRS interval

Answer 18

Less than 0.12, usually between 0.06 and 0.10seconds

Measured from the beginning of the QRS to the end of the QRS

Question 19

QT interval is measured from

Answer 19

The beginning of the QRS to the end of the T wave.

Question 20

The determine if a QT is prolonged,

Answer 20

Draw a line midway between the QRS complexes. If the T wave ends AFTER this line it’s prolonged.

Question 21

Memory method of estimating heart rate

Answer 21

300-150-100-75-60-50-43-37-33-30

Question 22

Little block method of estimating heart rate

Answer 22
