AMCA EKG EVALUATION EXAM 2025/2026 QUESTIONS
WITH ANSWERS RATED A+
✔✔What some causes for large, erratic spikes - ✔✔Somatic interference. Loose/dry
electrodes
✔✔What are some possible solutions for Large, erratic spikes - ✔✔Help patient relax;
wait for tremor
to subside
Reapply electrode; use new gel
tab
✔✔The heart consists of four layers: - ✔✔the pericardium, the layer or sac that
surrounds the heart; the
myocardium; the middle layer; the endocardium, the innermost layer and the epicardium
which
is the top layer.
✔✔Cardiac depolarization and repolarization occur when - ✔✔when these electrical
impulses develop and
spread through the myocardium.
✔✔by pacemaker
cells, an essential part of the conduction system. These cells, also known as cardiac
muscle
cells, can be characterized by any of the following terms: excitability, conductivity,
contractility,
and automaticity. - ✔✔The rate and rhythm of the heart are controlled by
✔✔Regulation of the heart rate, speed of electrical conduction and strength of
contraction are influenced by - ✔✔the brain via the autonomic nervous system.
✔✔Sinoatrial node (SA Node) - ✔✔pacemaker of the heart because it generates the
heart's rhythmic contractions.
✔✔Where is the SA node located? - ✔✔wall of right atrium
✔✔Atrioventricular node (AV node) - ✔✔specialized tissue in the wall between the atria
just above the ventricles
✔✔What happens after the impulse reaches the AV node, - ✔✔the atria contract
and the impulse are sent to the Bundle of HIS.
✔✔Bundle of HIS is also known as - ✔✔atrioventricular, AV bundle,
, ✔✔Where is the bundle of HIS located - ✔✔between the ventricles and splits into two
branches, forming the right
and left bundle branches, before sending the impulse to the Purkinje fibers.
✔✔Purkinje fibers, Purkinje network - ✔✔These fibers are located in the walls of the
ventricles. As the
impulse flows through the Purkinje fibers, it causes the ventricles to contract.
✔✔Interpreting Waveforms - ✔✔The results of the electrocardiogram are printed on a
special graph paper which travels through the electrocardiogram at a rate of about 25
millimeters per second. The graph paper has both horizontal and vertical lines which
serve to divide the paper into squares that are 5 millimeters in width and height. The
horizontal line measures time, while the vertical line measures amplitude or voltage.
✔✔Patient education is important when preparing the patient for an EKG. - ✔✔1.
Introduce yourself to the patient. Stress that privacy will be maintained.
2. Verify patient identification asking for 2 identifiers.
3. Explain the procedure in easy to understand terms for the patient.
4. Ask the patient if they have any questions or concerns about the EKG
procedure. Speak calmly and professionally.
5. Information will be asked of the patient and entered into the EKG machine.
6. Explain the procedure as follows:
✔✔Explain the EKG to the patient - ✔✔a. You will remove all clothing and jewelry from
your waist to your chin. You
will be given a gown to put on without tying it in the back.
b. Next, you will lie down on the exam table on your back.
c. Gel tabs will be placed on your legs, then arms and then your chest.
d. Next, small leads will be attached to the gel tabs.
e. You will be instructed not to talk or move during the tracing.
f. The technician will tell you when the tracing begins.
g. The technician will tell you when the tracing is over.
h. The technician will cover your chest area.
I. Once the provider has approved of the EKG, if necessary, the leads and
gel tabs will be removed, and you will be able to get dressed and leave.
✔✔P wave represents - ✔✔atrial depolarization (contraction)
of both the right and left atria, can be
characterized as a smooth, upward deflection which is approximately 0.10 second in
length.
✔✔PR interval represents? - ✔✔the time during which the impulse travels from the SA
node through
the atria to the ventricles.
