Monitoring and Telemetry (Introductionto Basic Cardiac Dysrhythmias) Chapter
2
Absolute Refractory Period - answer The period of time during which the cardiac cells
have not sufficiently repolarized and cannot contract again.
Artifact - answer Interference or static seen on the monitor.
Biphasic (Diphasic) - answer Going to two opposite directions; describes a complex
component that is both above and below the baseline.
Complex Components - answer Set of waves seen on a monitor, which represent an
electrical impulse traveling through the electrical conduction pathway of the heart; it
includes P, Q, R, S, and T waves
Electrode - answerAdhesive pad that is attached to the patient's skin.
Leads - answerSpecific placement of electrodes on the patient's skin to record electrical
activity.
Refractory period - answerTimes between depolarization and repolarization.
Relative Refractory Period - answerThe period of time during which cardiac cells have
repolarized enough that some cells can be stimulated to depolarize.
Rhythm - answerRegularity of the appearance of the complex components
R to R interval - answerLength of time between R wave and the next R wave
P to P interval - answerLength of time between one P wave and the next P wave.
PR (PRI) interval - answerRepresents the time it take an electrical impulse to be
conducted through the atria and atrioventricular node before the impulse begins to
cause ventricular depolarization.
ST Segment - answerThe portion of the line that leads form the end of the S wave to the
beginning of the T wave is the ST segment.
, The monitor shows the conduction of the electrical impulses through the heart, not the
actual contraction of the heart. True or False - answerTrue
Leads are color-coded wires and electrodes that connect the telemetry unit to the
patient's cardiac muscle. True or False - answerFalse
Leads II and MCL are the two Leads most often used to monitor patients because they
show electrical conduction throughout the heart muscle. - answerTrue
It is important to check complex formation, appearance, rhythm, and rate when
interpreting a rhythms strip. True or False - answerTrue
The P wave represents the depolarization of both right and left: - answerAtria
The normal PR interval measures: - answer0.12-0.20
The duration of a normal QRS complex is: - answer0.04 to 0.12
Identify the components and intervals included in one complete cardiac cycle. - answer-
P Wave
-PR Interval
-QRS complex
-ST segment
-T wave
-QT interval
-Baseline
The T wave represents: - answerrepolarization of the ventricales
A normal QT measures: - answerless then half of R to R
Explain how to calculate the heart rate using the 6-second rhythm strip method. -
answerCount the R in a 6 sec strip and multiply by 10.
Calculate the heart rate using both of the division methods when the distance between
two R waves is:
A. Three large squares:
B. Four large and two small squares: - answer300 /3 =100
300/4.4 = 68.18
List two facts about PR intervals that are important to measure when you are
interpreting a rhythm strip. - answerAre all PR intervals equal?
