Exam Overview
This 150-question comprehensive assessment is designed to reflect the structure and rigor of national
EKG Technician certification examinations such as those offered by organizations like the National
Healthcareer Association (NHA) and American Society of Phlebotomy Technicians (ASPT).
The exam evaluates competency across the full scope of practice, including:
Cardiac anatomy and physiology (15–20%)
Electrophysiology and conduction system (10–15%)
EKG equipment, lead placement, and troubleshooting (15–20%)
Rhythm interpretation and dysrhythmias (25–30%)
12-lead EKG analysis and myocardial infarction recognition (10–15%)
Stress testing and Holter monitoring (5–10%)
Infection control, safety, and emergency response (5–10%)
Ethics, patient communication, HIPAA, and legal standards (5–10%)
1. Which structure is responsible for initiating the electrical impulse of the
heart?
A. Atrioventricular node
B. Bundle of His
C. Purkinje fibers
D. Sinoatrial node
The sinoatrial (SA) node is the heart’s natural pacemaker and initiates
depolarization.
2. The normal resting heart rate for an adult is:
A. 40–60 bpm
B. 60–100 bpm
, C. 100–120 bpm
D. 120–160 bpm
Normal sinus rhythm in adults ranges from 60 to 100 beats per minute.
3. The P wave represents:
A. Ventricular depolarization
B. Ventricular repolarization
C. Atrial depolarization
D. Atrial repolarization
The P wave reflects atrial depolarization.
4. The QRS complex represents:
A. Atrial contraction
B. Atrial repolarization
C. Ventricular depolarization
D. Ventricular relaxation
The QRS complex corresponds to ventricular depolarization.
5. A PR interval longer than 0.20 seconds suggests:
A. Atrial fibrillation
B. Ventricular tachycardia
C. First-degree AV block
D. Sinus arrest
A prolonged PR interval indicates delayed AV conduction.
, 6. The electrical impulse normally travels from the SA node to the:
A. Purkinje fibers
B. Bundle branches
C. Atrioventricular node
D. Ventricles directly
Impulse flows SA node → AV node → Bundle of His → Bundle branches →
Purkinje fibers.
7. The T wave represents:
A. Atrial contraction
B. Ventricular depolarization
C. Ventricular repolarization
D. SA node firing
The T wave reflects ventricular repolarization.
8. Standard EKG paper speed is:
A. 10 mm/sec
B. 15 mm/sec
C. 25 mm/sec
D. 50 mm/sec
Standard calibration is 25 mm per second.
9. One small box on EKG paper equals:
A. 0.10 seconds
B. 0.04 seconds
, C. 0.20 seconds
D. 0.40 seconds
Each small box equals 0.04 seconds horizontally.
10.A heart rate of 45 bpm is classified as:
A. Tachycardia
B. Bradycardia
C. Fibrillation
D. Flutter
Heart rate below 60 bpm is bradycardia.
11.Proper placement of lead V1 is at the:
A. 5th intercostal space, midclavicular line
B. 4th intercostal space, midclavicular line
C. 4th intercostal space, right sternal border
D. 5th intercostal space, anterior axillary line
V1 is placed at the 4th intercostal space, right sternal border.
12.Limb leads measure electrical activity in the:
A. Horizontal plane
B. Frontal plane
C. Sagittal plane
D. Coronary plane
Standard limb leads view the frontal plane.
