Cardiac Cycle
Wave Forms
100
Located in the upper right corner of the atrium
What is SA Node
100

This chamber contracts and pushes blood into the systemic system exiting the heart

What is the left ventricle

100
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. Point of relaxation

What is diastole

100
First component of wave form.
What is p- wave.
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

Each vertical line on an ECG represents this and each small square equals?

What is voltage/strength and 0.1mV

400

How long on average is one cardiac cycle in seconds?

0.8 seconds

400
Represents the end of ventricular conduction and the beginning of recovery; a change may indicate MI
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 somatic tremor

500

The amount of blood the heart pumps in one minute typically around 6L

What is cardiac output

500
Tracks the atrial impulse from the SA node through the AV node, bundle of His, and bundle Branches.
What is PR intraval
