RELIAS DYSRHYTHMIA BASIC B EXAM 2025/2026
Sinus & Atrial Rhythms (10 Questions)
Question 1
An EKG strip shows a regular rhythm, heart rate of 75 bpm, P wave before each QRS, and
PR interval of 0.18 seconds. What is the rhythm?
A. Atrial fibrillation
B. Normal sinus rhythm
, C. Junctional rhythm
D. Ventricular tachycardia
Rationale: Normal sinus rhythm has a regular rhythm, heart rate 60–100 bpm, P wave
before each QRS, and PR interval of 0.12–0.20 seconds, per ACLS guidelines.
Analysis: Rate: 75 bpm; PR: 0.18 sec; QRS: normal (<0.12 sec).
Clinical Intervention: No action needed unless symptomatic.
Question 2
An EKG shows a heart rate of 120 bpm, regular rhythm, and normal P waves. What is the
rhythm?
A. Atrial flutter
B. Sinus tachycardia
C. Supraventricular tachycardia
D. Sinus bradycardia
Rationale: Sinus tachycardia has a regular rhythm, rate >100 bpm, and normal P waves, per
EKG standards.
Analysis: Rate: 120 bpm; PR: normal; QRS: normal.
Clinical Intervention: Assess for underlying causes (e.g., pain, fever, hypovolemia).
Question 3
An EKG shows irregular R-R intervals with no discernible P waves and a heart rate of 140
bpm. What is the rhythm?
A. Sinus tachycardia
B. Atrial fibrillation
C. Atrial flutter
D. Junctional rhythm
Rationale: Atrial fibrillation shows irregular R-R intervals and fibrillatory waves instead of
P waves, per EKG guidelines.
Analysis: Rate: 140 bpm; irregular; no P waves; QRS: normal.
Clinical Intervention: Assess hemodynamic stability; consider rate control (e.g., beta-
blockers).
Question 4
An EKG shows a sawtooth pattern with a 2:1 conduction ratio and a heart rate of 150 bpm.
What is the rhythm?
