1. A patient’s EKG shows a regular rhythm at 60 bpm, with each P wave
followed by a QRS complex and a PR interval of 0.18 seconds. This is
consistent with:
A. Sinus tachycardia
B. Normal sinus rhythm
C. Atrial fibrillation
D. First-degree AV block
The rhythm is regular, rate is normal, each P wave is followed by a QRS, and PR
interval is within normal range (0.12–0.20s).
2. Which of the following rhythms is characterized by an irregularly irregular
rhythm with no discernible P waves?
A. Sinus bradycardia
B. Atrial fibrillation
C. Atrial flutter
D. Ventricular tachycardia
AFib has irregular R-R intervals and absence of organized atrial activity.
3. A patient’s EKG shows a sawtooth pattern at a rate of 300 bpm in the atria
with a ventricular rate of 150 bpm. The rhythm is:
A. Sinus tachycardia
B. Atrial fibrillation
,2|Page
C. Atrial flutter with 2:1 conduction
D. Ventricular tachycardia
Sawtooth flutter waves are classic for atrial flutter; 2:1 conduction produces
ventricular rate of half atrial rate.
4. Which rhythm is characterized by wide QRS complexes (>0.12s), rate >100
bpm, and regular rhythm?
A. Sinus tachycardia
B. Ventricular tachycardia
C. Supraventricular tachycardia
D. Atrial fibrillation
Wide QRS and fast, regular rhythm suggest ventricular origin.
5. On EKG, a prolonged PR interval (>0.20 seconds) with each P wave
conducted to a QRS complex indicates:
A. Second-degree AV block type II
B. First-degree AV block
C. Third-degree AV block
D. Mobitz I
First-degree AV block shows constant prolonged PR intervals with normal
conduction.
6. A patient’s EKG shows progressive prolongation of PR interval until a P
wave is not conducted. This is characteristic of:
A. First-degree AV block
B. Second-degree AV block type II
C. Second-degree AV block type I (Mobitz I/Wenckebach)
D. Third-degree AV block
Mobitz I shows gradual PR prolongation with dropped QRS.

7. Which rhythm shows complete dissociation between P waves and QRS
complexes?
A. First-degree AV block
B. Second-degree AV block type I
C. Second-degree AV block type II
D. Third-degree AV block
Complete AV dissociation is diagnostic of third-degree (complete) heart block.
8. On a patient’s EKG, the QRS complex is wide with delta waves and short
PR interval. This suggests:
A. Left bundle branch block
B. First-degree AV block
C. Wolff-Parkinson-White syndrome
D. Atrial flutter
WPW shows pre-excitation (delta wave) and short PR interval.
9. Which rhythm is characterized by a “sawtooth” baseline with atrial rate
~250–350 bpm and variable ventricular response?
A. Sinus tachycardia
B. Atrial fibrillation
C. Atrial flutter
D. Ventricular tachycardia
Classic atrial flutter waves appear in II, III, aVF.
10. A patient presents with rapid, irregular rhythm and narrow QRS. The
likely diagnosis is:
A. Ventricular tachycardia
B. Sinus tachycardia
C. Supraventricular tachycardia with irregular conduction
D. Third-degree AV block
Narrow QRS tachycardia with irregularity suggests supraventricular origin.
, 4|Page
11. Which rhythm is characterized by absent P waves, irregularly irregular R-
R intervals, and narrow QRS?
A. Sinus tachycardia
B. Atrial fibrillation
C. Ventricular tachycardia
D. Junctional rhythm
Absence of P waves and irregular ventricular rhythm confirms AFib.
12. A patient’s EKG shows QRS >0.12s, rate 120 bpm, and uniform
morphology. The most likely diagnosis is:
A. Atrial fibrillation
B. Monomorphic ventricular tachycardia
C. Polymorphic VT
D. SVT
Monomorphic VT presents with wide, uniform QRS complexes.
13. Which EKG finding is classic for acute anterior myocardial infarction?
A. ST depression in II, III, aVF
B. ST elevation in V1–V4
C. Peaked T waves in V5–V6
D. U waves in V2
Anterior MI produces ST elevation in precordial leads.
14. ST elevation in leads II, III, aVF suggests:
A. Anterior MI
B. Lateral MI
C. Inferior MI
D. Posterior MI
Inferior MI affects the right coronary artery territory.
