A regular rhythm with a rate of 158 and a narrow QRS complex is
BEST defined as -ANSWERS-supraventricular tachycardia
Atrial tachycardia is best described as a rapid arrhythmia which -
ANSWERS-regular and occurs paroxysmally or is sustained
Which rhythm is characterized by P waves with three or more
morphologies? -ANSWERS-wandering atrial pacemaker
Normal sinus rhythm ranges from -ANSWERS-60-100 bpm
First degree AV block is determined by the measurement of the -
ANSWERS-PR interval
, Page |2
During sinus rhythm, an early narrow complex beat without a P
wave preceding it would be interpreted as: -ANSWERS-
premature junctional contraction
Atrial fibrillation is BEST defined as: -ANSWERS-chaotic,
asynchronous electrical activity in atrial tissue
Supraventricular tachycardia is -ANSWERS-narrow complex
tachycardia greater than 150bpm
The main cause of sinus arrhythmia in adults is -ANSWERS-
respiration
In lead II, what would indicate lead reversal? -ANSWERS-an
inverted QRS complex
The normal gain setting for ECG acquisition is -ANSWERS-10
mm/mV
, Page |3
__________ is one way to troubleshoot 60 cycle electrical
interference -ANSWERS-moving the ECG plug to a different
outlet
The hospital telemetry cardiac monitor technician notices a
significant wandering baseline on a newly admitted patient's ECG
tracings. Which of the following is the MOST LIKELY cause of the
wandering baselines? -ANSWERS-electrode placement
A technician receives an ECG recording that contains no
discernible cardiac information. What should be the FIRST step in
troubleshooting the problem? -ANSWERS-check the leads
On an ECG machine, what is the standard paper speed? -
ANSWERS-25 millimeters per second

An 84-year-old man is wearing a mobile cardiovascular telemetry
monitor with cellular real-time transmission capabilities for near
syncope. The patient's wife calls the monitoring center and asks
what the patient's ECG shows. The monitor tech notes normal
sinus rhythm at a rate of 74 bpm. The spouse then tells the
technician that her husband passed out at home and is breathing,
but unresponsive. What action is the MOST appropriate next step
for the monitor technician? -ANSWERS-activate EMS and assure
the wife help is on the way
ECG preliminary findings are MOST frequently recorded by the -
ANSWERS-nurse
What is a key component when contesting a denial of insurance
payment for a specific date of service provided? -ANSWERS-
testing report
Patients with atrial fibrillation are at risk for -ANSWERS-Emboli
While conducting a routine transtelephonic pacemaker check, the
patient states that he is short of breath and atrial fibrillation is
