EKG/ECG

1

100

This is known as the pacemaker of the heart

Sinoatrial Node

200

What makes up the conduction system of the heart.

Hint: 5

Sinoatrial Node

Atrioventricular Node

Bundle of His

R/L Bundle Branches

Purkinje Fibers

300

This wave includes Atrial depolarization and atrial contraction

P Wave

400

This blockage shows no QRS complex after the P wave, and the ventricles do not contract

2nd degree

500

Why is proper skin preparation important before placing EKG electrodes? 

Reduces electrical interference and ensures accurate, clear EKG readings

2

100

ECG was invented in what year?

1895

200

Who found the heartbeat and built a machine that could measure the electrical currents of the heart

Willem Einthoven

300

This wave includes 

Ventricular Repolarization

Ventricles Relaxing

Positive deflection

T Wave

400

This rhythm occurs when the atria contract faster than the ventricles.

Extra P waves are seen with regular QRS complexes

Atrial flutter

500

What does the QRS complex represent on a EKG

represents ventricular depolarization which leads to ventricular contraction 

3

100

sinus rhythm can include what additional rhythms? (2)

tacky and brady

200

Define deflection

Is any movement away from the baseline in a tracing

300

What is a PR Segment 

represents the time between the end of the atrial depolarization and the start of Ventricular depolarization

400

This term refers to placing the chest electrodes on the right side of the chest using the same intercostal spacing and landmarks

Dextrocardia

500

What patient instructions are important before obtaining an EKG?

instruct the patient to lie still breathe normally, avoid talking and relax

4

100

1 EKG block on a EKG paper equals how many seconds?

.04 seconds

200

With a Infant or a child under 90 lbs where does V4 placement go?

5th intercostal space, right mid- clavicular line

300

These appear as jagged peaks with irregular heights and spaces

somatic tremors

400

After how many seconds can V-Tach become life threatening 

a run longer than 30 seconds

500

Which EKG wave represents ventricular repolarization ?

T wave

5

100

the wave form and the isoelectric lines shift locations

Wandering baseline

200

term referring to extra heart beat

Ectopic

300

Early repolarization is related to what wave?

J Wave

400

This arrhythmia occurs when ventricles contract sooner than they should. An impulse originating in the ventricles creates this abnormality. 

PVCs

500

What is the normal duration of the PR interval

0.12-0.20 seconds
