Basic ECG Interpretation Jeopardy

Conduction and Anatomy

100

Known as the body's natural pacemaker

What is SA Node

200

This chamber contracts to send oxygenated blood through the aortic valve and out to the body or systemic system

What is the left ventricle

300

The chamber that receives oxygenated blood from the lungs

What is the left atrium

400

Main function is to delay impulses by 0.04 secounds to keep the ventricles from contraction too quickly.

What is the AV node

500

Extends from the Bundle Branches into the Endocardium and into the myocardial tissue.

What is purkinje fibers

ECG Leads and artifact

100

This limb electrode is used as the reference point/ground in an ECG

What is the right leg

200

After the first precordial electrode is placed, what is the correct order for the remaining electrodes

What is V2, V4, V3, V5, and V6 or V2, V4, V3, V6, and V5

300

This type of artifact is caused by patient muscle movement

What is somatic tremor

400

ECG artifact is seen on leads I and II this is the likely source of interference

What is the RA electrode

500

ECG artifact is seen on leads II and III, this is the likely source of interference

What is the the left leg electrode

ECG and other cardiac Testing

100

Normal paper speed for ECG

What is 25mm per second

200

ECG is the abbreviation for this instrument that measures heart function

Electrocardiogram

300

This moves against the tracing paper to record the waves of an ECG cycle

What is the stylus

400

Important part of the Holter monitor that provides a link to patient activity at the time of any abnormal findings. 

What is the patient diary

500

A stress test measures this in a patient

What is how the heart reacts to the need for increase O2 during exercise

Cardiac Cycle and conditions

100

Term used to describe a heart beat less that 60 beats per minue

Sinus Bradycardia

200

How long on average is one cardiac cycle in seconds?

0.8 seconds

300

The period when neither the ventricles or atria are contracting. Point of relaxation

What is diastole

400

The period of the cardiac cycle when both the atria and ventricles are contracting.

What is Systole

500

A reduction of blood flow to the heart

What is myocardial ischemia

Wave Forms and Rhythms

100

Represented by the P-wave, it shows electrical impulse starting in the SA node causing the atria to contract

What is atrial depolarization

200

This arrhythmia will result in death without immediate treatment

What is ventricular fibrillation

300

The arrhythmia viewed as a common disruption in rhythm

What is Premature ventricular contraction or PVC

400

Formula used for calculating heart rate using the QRS Complex

What is count the number of QRS complexes in 6 seconds and multiply by 10

500

The part of the cardiac cycle that is not seen on the waveform but instead is masked by the QRS complex

What is atrial repolarization
