B. The middle of the Q wave to the middle of the S wave
C. The end of the Q wave to the end of the S wave
D. Before the Q wave to after the end of the S wave - ANSWER-A. The

Which waveform represents ventricular repolarization on an ECG strip?
A. P wave
B. R wave
C. S wave
D. T wave - ANSWER-D. T wave
ECG preliminary findings are MOST frequently recorded by the:

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 monitor testing facility and asks what the patient's rhythm shows. The
monitor tech notes normal sinus rhythm at 74 bpm. The spouse then tells that
technician that her husband just passed out at home and is breathing but
unresponsive. Which action is the MOST appropriate next step for the monitor
technician?
A. Inquire about what medications he takes
B. Direct the wife to shake her husband gently
C. Activate the EMS, reassure the wife that help is on the way
D. Ask the wife whether the monitor is connected appropriately - ANSWER-C.
Activate the EMS, reassure the wife that help is on the way
______ is one way to troubleshoot 60-cycle ECG interference.
A. Having the patient hyperventilate
B. Adjusting the standardization mark
C. Cleaning the skin with isopropyl alcohol
D. Moving the ECG plug to a different outlet - ANSWER-D. Moving the ECG
plug to a different outlet
The normal gain setting for EKG acquisition is:
A. 5 mm/mV
B. 10 mm/mV
C. 15 mm/mV
D. 20 mm/mV - ANSWER-B. 10 mm/mV
,In lead II, what would indicate lead reversal?
A. ST elevation
B. An upright T-wave
C. An inverted QRS complex
D. a prolonged QRS complex - ANSWER-C. An inverted QRS complex
While conducting a routine trans telephonic pacemaker check, the patient states
he is short of breath and atrial fibrillation is noted in the presenting rhythm strip.
The technician's next step should be to:
A. Put the patient on hold and call his cardiologist
B. Put the patient on hold and call the pacemaker nurse
C. Finish up with the patient and move on to the next patient
D. Compare test results with past tests while the patient is on the phone -
ANSWER-D. Compare test results with past tests while the patient is on the
phone
What is the advantage of atrioventricular pacing?
A. It delivers direct stimulation to the ventricles to produce a ventricular
contraction
B. Both ventricles are stimulated to contract, compared to only the lower
portion of the right ventricle being stimulated
C. It mimics the normal cardiac conduction system and allows for the atria to
contract completely prior to the ventricles to allow for an atrial kick
D. The conduction system from the AV node through the ventricles is intact and
functioning - ANSWER-C. It mimics the normal cardiac conduction system and
allows for the atria to contract completely prior to the ventricles to allow for an
atrial kick
, What happens when one or both of the ventricular pathways are not functioning
properly due to damage or a delay from cardiac disease, drugs, or other
conditions?
A. A bundle branch block occurs
B. The patient experiences PVC's
C. A second-degree heart block, type I occurs
D. An idioventricular rhythm occurs - ANSWER-A. A bundle branch block
occurs
When is an atrial pacemaker used alone?
A. When conduction in the ventricles is not working properly
B. When the conduction system from the AV node through the ventricles are
intact and functioning
C. When the atria need to contract completely prior to the ventricles to allow for
atrial kick
D. When both ventricles are stimulated to contract - ANSWER-B. When the
conduction system from the AV node through the ventricles are intact and
functioning
When is a ventricular pacemaker used?
A. When conduction in the ventricles is not working properly
B. When the conduction system from the AV node through the ventricles is
