,INTRODUCTION
This certification-level set contains 35 original questions written for the Relias Learning Dysrhythmia
Basic Test, and every item was composed to reinforce the official course objectives for actual exam
readiness and clinical proficiency in cardiac rhythm interpretation. The items are organized across four
core domains that mirror the official Relias Dysrhythmia Basic content outline: Domain 1, Normal Sinus
Rhythm and Basic EKG Interpretation, with 9 questions; Domain 2, Atrial Dysrhythmias and
Arrhythmias, with 9 questions; Domain 3, Junctional and Ventricular Dysrhythmias, with 9 questions;
and Domain 4, Heart Blocks and Advanced Rhythm Interpretation, with 8 questions. Each question
includes a labelled 6-second Lead II rhythm strip recorded at 25 mm per second and 10 mm per millivolt,
one correct answer, and a rationale that demonstrates the measurement, the rate calculation, and the
electrophysiological logic behind the correct interpretation or intervention. No two questions in the set
require the same calculation, the same rule, or the same data interpretation, so the full set gives the
candidate broad coverage of the official content outline. All content is original and aligned to the
2026/2027 academic year for candidates who are working toward the actual examination.

, ACTUAL QUESTIONS
Domain 1: Normal Sinus Rhythm and Basic EKG Interpretation
Question 1. A 6-second Lead II rhythm strip is displayed above. Which interpretation of the
rhythm is correct?
Rhythm strip 1. Lead II, 25 mm/second, 10 mm/mV.
A. Atrial fibrillation with slow ventricular response
B. Sinus rhythm with second-degree AV block, Type II
C. Normal sinus rhythm at 75 beats per minute
D. Ventricular tachycardia at 75 beats per minute
Correct Answer: C
Rationale: Every QRS complex is preceded by an upright, uniform P wave at a fixed PR interval of 0.16
second, and the QRS duration stays under 0.12 second, which satisfies the Relias Learning blueprint
definition of normal sinus rhythm. Measured with Dubin's method, each R-to-R interval spans 20 small
boxes (0.80 second), so 1500 divided by 20 gives 75 beats per minute and confirms an atrial and
ventricular rate inside the normal 60-to-100 range. The electrophysiological logic is that the sinoatrial
node depolarizes the atria, the impulse pauses at the AV node, and rapid His-Purkinje conduction
activates both ventricles almost simultaneously, producing the narrow complex that excludes a
ventricular origin.
Question 2. Using the 6-second method on the strip displayed above, what is the
ventricular rate?
Rhythm strip 3. Lead II, 6-second span marked, 25 mm/second.
A. 40 beats per minute
B. 100 beats per minute
C. 150 beats per minute
D. 80 beats per minute
Correct Answer: D
Rationale: The 6-second method counts the R waves inside a 6-second span and multiplies by 10; eight
QRS complexes fall inside that span, so the ventricular rate is 80 beats per minute. The Relias Learning
blueprint presents this as the fastest way to estimate rate when the rhythm is irregular or when the
clinician needs a rapid bedside answer, and the measured R-to-R interval of roughly 15 small boxes
(0.75 second) reproduces the same value through the 1500 method. The physiological principle is that
rate equals the number of ventricular depolarizations per minute, so counting the ventricular
depolarizations inside a known time window is valid regardless of the atrial mechanism.
