Which of the following leads would help to record the electrical activity in the heart's
horizontal plane?
-Bipolar lead
-12-lead ECG
-Precordial leads
-Unipolar leads - CORRECT ANSWERS-Precordial leads
This provides a transverse view through the middle of the heart which divides it into
upper and lower portions.
Of the electrocardiogram waves, which would be considered the first deflection after the
diastole that is produced because of the atrial depolarization?
-T wave
-S wave
-Q wave
-P wave - CORRECT ANSWERS-P wave
This occurs because of the atrial depolarization of the heart.
The Bundle of His has an intrinsic firing rate of which of the following?
-40 to 60 beats per minute
-30 to 60 beats per minute
-60 to 80 beats per minute
-80 to 100 beats per minute - CORRECT ANSWERS-40-60 beats per minute
The Bundle of His is located at the superior portion of the interventricular septum. The
Bundle of His is actually the pathway of the electrical impulses that lead out of the SA
node.
If a patient is experiencing a low blood pressure, which of the following terms would be
correct?
-Hyper tension
,-Hypoxemia
-Hypotension
-Hypoplastic - CORRECT ANSWERS-Hypotension
Hypertension: high blood pressure
Hypoxemia: low oxygen concentration in the blood
Hypoplastic: when an organ is abnormally small because of a problem with
development prior to birth
Hypotension: low blood pressure
The aVR lead picks up electrical activity from which of the following?
-The center of the heart to the right arm
-The center of the heart to the left leg
-The center of the heart to the left arm
-From the left arm to the left leg - CORRECT ANSWERS-The center of the heart to the
right arm
The center of the heart to the left leg: aVF
The center of the heart to the left arm: aVL
The center of the heart to the right arm: aVR
From the left arm to the left leg: lead III
The Q wave should have a duration of less than how many seconds?
-0.30 seconds
-0.20 seconds
-0.10 seconds
-0.04 seconds - CORRECT ANSWERS-0.04 seconds
The Q wave should have a duration of less than 0.04 seconds. It is the first negative
component of the QRS complex and if it lengthens, it could be indicative of a myocardial
infarction
When the mitral valve opens, the blood flows from the left atrium to which of the
following?
-The right atrium
-The left ventricle
-The right ventricle
-The lungs - CORRECT ANSWERS-The left ventricle
Which of the following age groups would be most likely to experience fibrosis in the
conduction system?
-21-30 years of age
, -Infants
-The elderly
-40-60 years of age - CORRECT ANSWERS-The elderly
Fibrosis can occur at any age, but is most common with the elderly. They have a higher
incidence of AV block which can be caused by fibrosis in the conduction system
A dropped beat indicates what? (Skipped QRS wave)
____ degree heart block, type __ - CORRECT ANSWERS-Second degree heart block,
type I
With this rhythm, the PR interval will lengthen in each of the intervals until one QRS
completely disappears.
Which of the following characteristics would a good ECG technician have?
-They should be reliable
-They should have mechanical aptitude
-They should be able to follow directions
-All of the above - CORRECT ANSWERS-All of the above
Which of the following would be the main purpose of the heart valves?
-The prevention of back-flow of blood
-They assure that there is a uni-directional flow of blood through the heart
-Both A and B
-None of the above - CORRECT ANSWERS-Both A and B
Which of the following would be considered correct regarding the grid paper that is used
for an ECG?
-The grid paper consist of horizontal lines
-The grid paper is not heat sensitive
-The grid paper consist of vertical lines
-Both A and C - CORRECT ANSWERS-Both A and C
The grid paper that is used for an ECG test:
Consists of horizontal lines
Consists of vertical lines
Is heat sensitive
Is used for cardiac monitoring and ECG's
If a patient's heart becomes softened, it could cause changes in the electrocardiogram.
Which of the following terms would be considered correct for a softening of the heart?
-Cardiomegaly
-Cardiopathy
