100
Located in the upper right corner of the atrium
What is SA Node?
100
This measurement of a small box on the EKG paper from left to right.
What is 0.04 seconds
100
This EKG form represents atrial depolarization.
What is the P wave?
100
Rate: 60-100 Rhythm: Regular P-Waves / PRi: 1:1 and 0.12 to 0.20 QRS: 0.06 - 0.10 QTi: less than half of the preceding R-R interval
What is Normal Sinus Rhythm?
100
Represents no electrical activity in the heart.
What is Asystole?
200
Extends from the Bundle Branches into the Endocardium and into the myocardial tissue of the ventricle.
What are the purkinje fibers?
200
This is the normal duration of a QRS complex when measured from left to right.
What is 0.06 - 0.10?
200
This EKG form represents repolarization of the ventricles.
What is the T wave?
200
Rate: 40-60 Rhythm: Regular P-Waves / PRi: Absent, Inverted, or retrograde QRS: 0.06 - 0.10 QTi: less than half of the preceding R-R interval
What is Junctional Rhythm
200
When there is electrical activity but no mechanical activity.
What is Pulseless Electrical Activity (PEA)?
300
Main function is to delay impulses by 0.04 seconds to keep the ventricles from contracting too quickly.
What is the AV node?
300
This is the normal duration of a P wave + the PR segment when measured from left to right.
What is 0.12 to 0.20
300
Represents the end of ventricular conduction and the beginning of recovery; a change may indicate MI.
What is ST segment?
300
Rate: 123-146 (variable) Rhythm: Irregular P-Waves / PRi: not measurable QRS: 0.06 - 0.10 QTi: less than half of the preceding R-R interval
What is Atrial Fibrillation with a Rapid Ventricular Response
300
A wide complex Tachycardia that may or may not have a pulse.
What is Ventricular Tachycardia (VT)?
400
Located between the left & right bundle branches and AV node.
What is Bundle of His?
400
The rate is this fast when there are 4 large boxes between regularly occurring R waves.
What is 75 beats per minute?
400
Usually the central and most visually obvious part of the normal EKG tracing.
What is the QRS complex?
400
Rate: 190 Rhythm: Regular P-Waves / PRi: not measurable, possibly buried in T wave QRS: 0.06 - 0.10
What is SVT?
400
Chaotic electrical activity.
What is Ventricular Fibrillation (VF).
500
Please state the correct path of electricle impulses through the heart.
What is SA,AV,Bundle of His, Bundle Branches, Purkinje Fibers
500
On EKG paper, 15 large boxes from left to right.
What is 3 seconds?
500
EKG form sometimes seen with states of hypokalemia.
What is a U wave?
500
Rate: 85 Rhythm: Regular or slightly irregular P-Waves / PRi: saw toothed pattern 3:1 QRS: 0.06 - 0.10 QTi: less than half of the preceding R-R interval
What is Atrial Flutter?
500
This congenital electrical condition places you at risk for VT or VF.
What is Long QT syndrome?
