EKG Flashcards
The technician should set the paper speed on the EKG machine to 50 mm/second for a patient who has a fast heart rate.
The technician should recognize that leads V1 and V2 record electrical
Leads I and V6 record electrical activity of the lateral wall of the left ventricle. These leads do not record electrical activity of the septal wall.
Leads I and V6
Leads aVL and V5 record electrical activity of the lateral wall of the left ventricle. These leads do not record electrical activity of the septal wall.
Leads aVL and V5
Leads III and aVF record electrical activity of the inferior wall of the left ventricle. These leads do not record electrical activity of the septal wall.
Leads III and aVF
supine with the arms at the side
This is the appropriate position for a standard 12-lead EKG, not a nuclear stress test.
Supine with the arms above the head
During a nuclear stress test, the patient should be in a supine position with the arms above the head so the camera can rotate around the patient to produce a multidimensional image.
Right-side lying with the arms slightly extended
This is not the appropriate position for a nuclear stress test.
Sitting upright with the head tilted back
This is not the appropriate position for a nuclear stress test.
speed
The speed control is used to control the speed at which the paper runs during recording. It does not control or regulate the output or height of the EKG waveforms.
output display
The output display is the screen that shows the EKG tracing. It does not control or regulate the output or height of the EKG waveforms.
Artifact filter
The artifact filter decreases artifacts or abnormal marks on the EKG tracing. It does not control or regulate the output or height of the EKG waveforms.
Gain
The technician should use the gain control to adjust the height of the waveform.
50mm/second
The technician should set the paper speed on the EKG machine to 50 mm/second for a patient who has a fast heart rate.
25 mm/second
A patient who is experiencing accelerated junctional rhythm has a heart rate of 60 to 100/min. The technician should use the standard paper speed setting of 25 mm/second.
10mm/second
The technician should set the paper speed on the EKG machine to 10 mm/second if the patient has a slow heart rate.
5mm/second
The technician should set the paper speed on the EKG machine to 5 mm/second if the patient has a slow heart rate.
The technician should first check the patient’s respiratory rate. Checking the patient’s respiratory rate will allow the technician to confirm hyperventilation.

in a healthy adult patient, which of the following is expected shape and direction of the p wave in lead 11
(rounded and upright)
Normal atrial depolarization moves in the direction of the left leg, or the positive electrode, causing an upright and rounded wave. This is an expected finding in a healthy adult patient.
Rounded and inverted
p wave inversion indicates depolarization of the atria opposite of the expected direction and is not an expected finding in a healthy adult patient.
peaked and inverted
P wave inversion indicates depolarization of the atria opposite of the expected direction and is not an expected finding in a healthy adult patient.
peaked and upright
Peaked P waves indicate atrial enlargement and are not an expected finding in a healthy adult patient.
