AMCA EKG Practice Exam Q&A | Verified 2025/2026 Content | Exam-Aligned |
Certification-Ready for EKG Technicians
1. What is the primary purpose of an electrocardiogram (EKG/ECG)?
a) To measure blood pressure
b) To record the electrical activity of the heart
c) To assess lung function
d) To monitor blood glucose levels
b) To record the electrical activity of the heart
Rationale: An EKG records the heart’s electrical impulses to assess cardiac rhythm and
function.
2. How many leads are used in a standard 12-lead EKG?
a) 6
b) 10
c) 12
d) 15
c) 12
Rationale: A standard 12-lead EKG uses 10 electrodes to produce 12 different views of the
heart’s electrical activity.
,3. Where is the V1 lead placed?
a) Left midclavicular line, 5th intercostal space
b) Right sternal border, 4th intercostal space
c) Left anterior axillary line
d) Midsternum
b) Right sternal border, 4th intercostal space
Rationale: The V1 lead is placed at the right sternal border in the 4th intercostal space for
accurate chest lead recording.
4. What does the P wave represent on an EKG?
a) Ventricular depolarization
b) Atrial depolarization
c) Ventricular repolarization
d) Atrial repolarization
b) Atrial depolarization
Rationale: The P wave reflects the electrical activity of atrial depolarization during contraction.
5. Which rhythm is characterized by a heart rate greater than 100 beats per
minute?
a) Bradycardia
b) Tachycardia
c) Normal sinus rhythm
d) Asystole
b) Tachycardia
Rationale: Tachycardia is defined as a heart rate exceeding 100 beats per minute.
6. What is the normal duration of the PR interval?
a) 0.04–0.08 seconds
b) 0.12–0.20 seconds
c) 0.20–0.30 seconds
d) 0.30–0.40 seconds
b) 0.12–0.20 seconds
Rationale: The PR interval, measuring atrial depolarization and AV node conduction, normally
lasts 0.12–0.20 seconds.
7. What is a common cause of EKG artifacts?
a) Proper lead placement
b) Patient movement
c) Correct electrode adhesion
d) Stable power source
b) Patient movement
Rationale: Patient movement can cause baseline wander or irregular waveforms, leading to
artifacts.
8. Which lead is considered the rhythm strip lead?
a) Lead I
, b) Lead II
c) Lead V1
d) Lead aVR
b) Lead II
Rationale: Lead II is commonly used as the rhythm strip lead due to its clear P wave and QRS
complex visibility.
9. What does the QRS complex represent?
a) Atrial depolarization
b) Ventricular depolarization
c) Atrial repolarization
d) Ventricular repolarization
b) Ventricular depolarization
Rationale: The QRS complex reflects the electrical activity of ventricular depolarization.
10. What is a normal heart rate range for an adult at rest?
a) 40–60 beats per minute
b) 60–100 beats per minute
c) 100–120 beats per minute
d) 120–140 beats per minute
b) 60–100 beats per minute
Rationale: A normal resting heart rate for adults ranges from 60 to 100 beats per minute.
11. What is the correct placement for the right arm (RA) electrode?
a) Right chest
b) Right shoulder or upper arm
c) Left leg
d) Left chest
b) Right shoulder or upper arm
Rationale: The RA electrode is placed on the right shoulder or upper arm for accurate limb lead
recording.
12. Which arrhythmia is characterized by a "sawtooth" pattern on the EKG?
a) Atrial fibrillation
b) Atrial flutter
c) Ventricular tachycardia
d) Premature ventricular contraction
b) Atrial flutter
Rationale: Atrial flutter shows a characteristic "sawtooth" pattern due to rapid, regular atrial
activity.
13. What is the first step in preparing a patient for an EKG?
a) Apply electrodes
b) Explain the procedure to the patient
c) Calibrate the EKG machine
d) Clean the skin with alcohol
