OH Policy & Procedure
100
The top two chambers of the heart
What are the atria?
100
This may be seen with excessive movement. Waves may appear bumpy, wavy, or tremulous.
What is artifact?
100
This is called the pacemaker of the heart
What is the SA node?
100
The normal duration for the P wave
What is 0.12 to 0.20 seconds?
100
The rhythm seen in this strip
What is normal sinus rhythm?
100
Occurs at the beginning of every shift, between PCTs
What is telemetry report?
200
Another name for cardiac muscle
What is the myocardium?
200
The time value of the smaller squares within the larger squres on the telemetry strip
What is 0.04 seconds?
200
The node responsible for delaying impulses by 0.04 seconds to keep ventricles from contracting too quickly
What is the AV node?
200
Normal duration is 0.06 to 0.12 seconds, or half the PR interval
What is the QRS complex?
200
Referring to the rhythm strip below, this rhythm is regular, at a rate of less than 60 bpm
What is sinus bradycardia?
200
As long as there are no changes, this is how often the PCT documents the patient's telemetry rhythm
What is every 8 hours?
300
The large vessel that carries unoxygenated blood to the lungs
What is the pulmonary artery?
300
Commonly used for routine monitoring. It is especially useful for detecting sinus node and atrial arrhythmias.
What is Lead II?
300
The rate the Purkinje Fibers impulses discharge
What is 20 to 40 times?
300
A measurement of the duration from the beginning of the P wave to the beginning of the QRS complex, normal value 0.12 to 0.20 second
What is the PR interval?
300
Referring to the rhythm strip below, the rhythm is regular, fast, and the pr interval may be shorter or difficult to see 
What is supraventricular tachycardia (SVT)?
300
The staff member who must be contacted when there are no telemetry units available
Who is the Nursing Supervisor?
400
The large vessel that carries blood to the rest of the body
What is the aorta?
400
This is done by counting the number of complete cycles per minute
What is calculating the heart rate?
400
This is located between the bundle branches and the AV node
What is the Bundle of His?
400
The segment that represents depolarization and repolarization of the ventricles
What is the QT interval?
400
Referring to the strip below, this rhythm indicates the atria are quivering
What is atrial fibrillation (A fib)?
400
From the policy:
Remove the batteries.
Take to the soiled utility room and clean the pack and wire using a hospital approved disinfectant
Check leads and replace wires as needed
What needs to be done to store telemetry units?
500
These include the tricuspid, pulmonary, mitral, and aortic
What are the 4 valves in the heart?
500
It takes this many of the squares pictured below to create a six second strip
What is 30?
500
The correct pathway of electrical conduction through the heart
What is SA node, AV node, Bundle of His, Bundle Branches, and Purkinje Fibers?
500
Elevation of this segment may indicate an MI
What is the ST segment?
500
Referring to the rhythm strip below, it is an emergency
What is Ventricular Tachycardia (V tach)?
500
-A problem with electrodes, batteries, or 60 second cycling pattern.
-Change in rhythm
-Increased ectopy
What are reasons to notify the nurse?
