Sample Free EKG Practice Test with Answers
Below are sample questions designed to mimic typical EKG interpretation challenges. Each question is followed by a detailed explanation of the answer.
Question 1: Recognizing Normal Sinus Rhythm
Which of the following characteristics best describes a normal sinus rhythm on an EKG?
- Regular rhythm with a rate of 55 bpm
- Irregular rhythm with absent P waves
- Rhythm with P waves before each QRS complex, at a rate of 75 bpm
- Ventricular tachycardia pattern
Answer: c. Rhythm with P waves before each QRS complex, at a rate of 75 bpm
Explanation: Normal sinus rhythm is characterized by a regular rhythm with a heart rate between 60-100 bpm, presence of P waves before each QRS complex, and a consistent P-QRS-T pattern. Choice c accurately describes this pattern.
Question 2: Identifying Atrial Fibrillation
Which EKG feature indicates atrial fibrillation?
- Regular P waves with a consistent QRS pattern
- Irregularly irregular rhythm with no discernible P waves
- Wide QRS complexes with T wave inversion
- Prolonged PR interval
Answer: b. Irregularly irregular rhythm with no discernible P waves
Explanation: Atrial fibrillation is characterized by an irregularly irregular ventricular rhythm and absence of distinct P waves due to chaotic atrial activity. This pattern is a hallmark of atrial fibrillation.
Question 3: Detecting Ventricular Tachycardia
Which feature is most indicative of ventricular tachycardia on an EKG?
- Regular, wide QRS complexes at a rate over 100 bpm
- Normal QRS width with rapid P waves
- Irregular rhythm with absent QRS complexes
- Prolonged QT interval with T wave abnormalities
Answer: a. Regular, wide QRS complexes at a rate over 100 bpm
Explanation: Ventricular tachycardia presents as a fast (usually >100 bpm), regular rhythm with wide QRS complexes (>120 ms). Recognizing these features is essential for prompt diagnosis and treatment.
More Practice Questions for EKG Interpretation
To further enhance your skills, here are additional questions with answers:
Question 4: Recognizing ST Segment Elevation
- What does ST segment elevation generally indicate? Myocardial infarction or acute ischemia
- How is ST elevation measured? By comparing the ST segment to the baseline (isoelectric line) in multiple leads
Question 5: Assessing Heart Rate Using the 6-Second Method
- How do you calculate the heart rate using the 6-second strip? Count the number of QRS complexes in 30 large squares (6 seconds) and multiply by 10.
- Example: 8 QRS complexes in 6 seconds = 80 bpm.
