100
Located in the upper right corner of the atrium
What is SA Node
100
About the size of a human fist.
What is the size of a human heart.
100

This lead is commonly used for routine monitoring and is useful for detecting sinus and atrial arrhythmias.

What is lead II

100
The period when neither the ventricles or atria are contracting.
What is diastole
100

Also referred to as the EKG baseline and denotes resting membrane potentials.

What is Isoelectric line?

200
Extends from the Bundle Branches into the Endocardium and into the myocardial tissue.
What is purkinje fibers
200
Located between the left atria and left ventricle.
What is mitral valve
200
Direction that time is measured on telemetry strip.
What is Horizontal
200
The amount of blood pumped out of a ventricle after one contraction
What is stroke volume
200
Follows the P wave and represents depolarization of the ventricles.
What is the QRS
300
Main function is to delay impulses by 0.04 secounds to keep the ventricles from contraction too quickly.
What is the AV node
300
The muscular wall of the heart consisting mainly of cardiac muscle.
What is myocardium
300
First small wave seen on cardiac strip.
What is p-wave.
300
The period of the cardiac cycle when both the atria and ventricles are contracting.
What is Systole
300

Represents ventricular recovery or repolarization.

What is t-wave

400
located between left & right bundle branches and AV node.
What is Bundle of His
400
The sac that surrounds the heart.
What is pericardium.
400
Continous information about heart's electrical activity to monitor cardiac status.
What is telemetry
400
The amount of pressure the LV must work against to pump blood into the circulation.
What is afterload
400

Represents the time between ventricular depolarization and repolarization.

What is ST segment

500
Please state the correct path of electricle impulses through the heart.
What is SA,AV,Bundle of His, Bundle Branches, Purkinje Fibers
500
The 4 valves of the heart.
What is the tricuspid, mitral,aortic,& pulmonic.
500
May be seen with excessive moving; the baseline appears wavy, bumpy and tremulous.
What is artifact
500
The amount of blood the heart pumps in one minute.
What is cardiac output
500

Reflects electrical conduction through the AV node.

What is PR intraval
