UPDATED ACTUAL Exam Questions and
CORRECT Answers
AC interference - CORRECT ANSWER✔✔- Electrical interference that appears as small,
uniform spikes on ECG tracking
Amplifier - CORRECT ANSWER✔✔- Device on the ECG that magnifies or enlarges the
heart's electrical impulses so they can be recorded
arrhythmia - CORRECT ANSWER✔✔- Abnormal heart rate, rhythm and conduction system
dysrhthmia - CORRECT ANSWER✔✔- Abnormal heart rate, rhythm and conduction system
artifact - CORRECT ANSWER✔✔- Unwanted changes in an ECG tracing caused by
movement, machine malfunction or other factors
atrioventricular node (AV) - CORRECT ANSWER✔✔- Knot of specialized cells in the
lower portion of the right atrium that produces the heart's electrical impulses
augmented leads - CORRECT ANSWER✔✔- leads that measure cardiac activity from one
electrode on the body at a time; recordings are made larger so they can be read
baseline - CORRECT ANSWER✔✔- Line that separates the various cardiac waves;
representative of the space between heartbeats while the heart is "resign" AKA iosoelectric
line
bipolar leads - CORRECT ANSWER✔✔- standard limb leads
bundle banches - CORRECT ANSWER✔✔- branches of cardiac fibers that receive electrical
impulses from the bundle of His
,bundle of His - CORRECT ANSWER✔✔- small band of atypical cardiac muscle fibers that
receive electrical impulses from the AV node
cardiac cycle - CORRECT ANSWER✔✔- one heartbeat; one contraction/relaxation phase of
the heart
precordial leads - CORRECT ANSWER✔✔- chest leads that measure in only one direction
depolarization - CORRECT ANSWER✔✔- discharge of electrical energy that causes
contraction such as in heart muscle
electrocardiogram - CORRECT ANSWER✔✔- graphic picture of the heart's electrical
activity
electrocardiograph - CORRECT ANSWER✔✔- machine that records the electrical activity
of the heart
electrocardioraphy - CORRECT ANSWER✔✔- noninvasive procedure used to detect the
heart's electrical activity
electrodes - CORRECT ANSWER✔✔- devices made of a conductive material to pick up the
electrical activity of the heart; sensors
Holter monitor - CORRECT ANSWER✔✔- ambulatory heart monitor that records heart
activity during a 24-48 hour period
interval - CORRECT ANSWER✔✔- ECG pattern that shows the length of a wave with a
sigment
ischemia - CORRECT ANSWER✔✔- poor blood supply to body tissue causing a lack of
oxygen to that tissue
,leads - CORRECT ANSWER✔✔- covered wires that carry electrical impulses from the
sensor to the ECG machine
MI - myocardial infactction - CORRECT ANSWER✔✔- heart attack; death of heart tissue
caused by blockage of the heart's blood vessels
Normal Sinus Rhythm (NSR) - CORRECT ANSWER✔✔- rhythm measurement that starts
at the SA node, occurs within an established time frame, and follows an expected, established
pattern
P wave - CORRECT ANSWER✔✔- ECG pattern that shows atrial contraction originating at
the SA notde
pacemaker - CORRECT ANSWER✔✔- devie that delivers electrical impulses to the heart
muscle when the SA node is unable to do so
PAT, paroxysmal atrial tachycardia - CORRECT ANSWER✔✔- sudden onset and ending of
atrial tachycardia, 150-250 bpm
polarization - CORRECT ANSWER✔✔- phase when the heart is in a ready state to contract
PR interval - CORRECT ANSWER✔✔- time interval between atrial contraction and the
beginning of ventricular contraction
PR segment - CORRECT ANSWER✔✔- time interval necessary for an electrical impulse to
cause contraction of the atria and begin contraction of the ventricles
PAC premature atrial contractions - CORRECT ANSWER✔✔- condition in which an
electrical impulse in the atria starts before the next expected heartbeat
PVC premature ventricular contractions - CORRECT ANSWER✔✔- condition in which the
ventricles receive an impulse prematurely and contract early
, Purkinje fibers - CORRECT ANSWER✔✔- cardiac fibers that receive impulses from the
bundle branches and take them throughout the heart muscle
QRS complex - CORRECT ANSWER✔✔- ECG pattern that shows when the impulse
moves through the ventricles and reaches the Purkinje fibers, depicting contracction of both
ventricles
QT interval - CORRECT ANSWER✔✔- time interval on ECG that shows the time needed
for the ventricles to contract and recover
repolarization - CORRECT ANSWER✔✔- rest phase of the ECG cycle
rhythm strip: - CORRECT ANSWER✔✔- lead II recording on ECG that show the heart's
rhythm
segment - CORRECT ANSWER✔✔- ECG pattern between two waves
SA node sinoatrial - CORRECT ANSWER✔✔- Pacemaker of the heart, knot of specialized
cells cells located in the upper right atrium
sinus bradycardia - CORRECT ANSWER✔✔- slow heart rate, less than 60bpm
somatic tremor - CORRECT ANSWER✔✔- body tremor caused by voluntary or involuntary
muscle movement
ST segment - CORRECT ANSWER✔✔- time interval between the ventricular contraction
and the beginning of ventricular relaxation
standard limb lead - CORRECT ANSWER✔✔- insulated device that carries the electrical
impulses to the ECG and traces the electrical impulse of the heart in two different directions
simultaneously
