100
Represents Atrial depolorization or contraction
What is the P Wave
100
The line between the P wave and the QRS complex
What is the PR segment.
100
Begins at the onset of the P-wave and ends at the beginning of the QRS complex
What is the PR interval
100
It is the primary pacemaker of the heart.
What is SA node
100
Is term used to describe the period of recovery that cells need before they can respond to another stimulus.
What is refractoriness
200
Represents Ventricular repolorization
What is the T-wave
200
The space between the QRS complex and the T wave.
What is the ST segment.
200
Begins at the QRS complex and ends at the end of the T-wave.
What is the QT-interval.
200
The SA node is located in this part of the heart
What is right atrium
200
The period of time where the cardiac cells will not respond to a further stimulus no matter how strong the stimulus
What is the absolute refractory period
300
Represents ventricular depolorization
What is the QRS complex
300
The space/line between the T-wave and the next P wave.
What is the TP segment.
300
the normal duration of a PR-interval.
What is 0.12 to 0.20 seconds.
300
The intrinsic rate of the AV-junction
What is 40-60 beats per minute.
300
Corresponds with the end of the T-wave
What is the supernormal period.
400
The negative waveforms after the P wave
What is the Q and the S waves
400
The point where the QRS complex and the T-wave meet.
What is the J-point.
400
PR interval are composed of these two things/parts.
What is the P-wave and the PR segment
400
The right and left bundle branches recieve an impluse from this part of the conduction.
What is the bundle of His.
400
Absolute refractory period measures from here to here.
What is the begin of the QRS complex to the peak of the T-wave
500
Thought to represent repolorization of the purkinje fibers.
What is the U wave.
500
The J-point is above the baseline, it results in this condition.
What is ST-segment elevation.
500
These are stimulated during the PR-interval.
What is the Atria, av juction, bundle of his, right and left bundle branches and purkinje fibers.
500
The AV-junction recieves impulses from this part of the conduction system.
What is the SA node.
500
The relative refractory period measures from here to here.
What is the peak of the T-wave to the end of the T-wave.
