EKG Rhythm Quiz Questions
. Are you ready to put your knowledge of EKG rhythms to the test? Take our engaging and informative quiz to see how much you really know! An electrocardiogram (EKG) is a quick and painless test that records the electrical activity of the heart. Our quiz features a wide range of questions, including image-based questions where you’ll be asked to identify the rhythm. If you find this quiz helpful and learn something new, don’t hesitate to share it with your friends and peers. Let’s get started!
- 1.
What is this rhythm?
- A.
Sinus rhythm
- B.
Atrial fibrillation
- C.
Sinus bradycardia
- D.
Sinus tachycardia
Correct Answer
C. Sinus bradycardiaExplanation
It's regular; there are P waves, the QRS is normal, and the PR interval is normal – it's just a slow rate.Rate this question:

- 2.
What is this rhythm?
- A.
Ventricular fibrillation
- B.
Sinus tachycardia
- C.
Atrial flutter
- D.
Atrial fibrillation
Correct Answer
D. Atrial fibrillationExplanation
It's irregular; there aren't P waves, just those messy wavy lines! Atrial flutter is REGULAR - and the "messy wavy lines" are taller and look more like "sawtooth" waves.Rate this question:

- 3.
What is this rhythm?
- A.
Ventricular fibrillation
- B.
Ventricular tachycardia
- C.
Atrial fibrillation
- D.
PVC's
Correct Answer
A. Ventricular fibrillationExplanation
Just a bunch of wavy lines, about "1 box" high on average! If this continues, it will become an asystole (flat line).Rate this question:

Atrial flutter

Sinus tachycardia
- C.
Sinus rhythm
- D.
PVC's
Correct Answer
B. Sinus tachycardiaExplanation
It's regular; there are P waves, the QRS is normal, the PR interval is normal, and it's just fast!Rate this question:

What is this rhythm?
- A.
Atrial fibrillation
- B.
PVC's
- C.
Ventricular tachycardia
- D.
Atrial flutter
Correct Answer
D. Atrial flutterExplanation
It's regular, no P waves, just these "sawtooth" flutter waves. Atrial FIBRILLATION is irregular, and the "sawtooth" waves are smaller.Rate this question:

- 6.
What is the beat circled?
- A.
Junctional escape beat
- B.
Premature ventricular contraction
- C.
Ventricular tachycardia
- D.
Flutter wave
Correct Answer
B. Premature ventricular contractionExplanation
It is a PVC. This is a "big ugly beat" – it's wider than the others and just seems to have been thrown in there! Notice how different it looks, and it causes a slight pause after it - that's the time the heart took to recover from it. Ventricular tachycardia is more than one of these in a row.Rate this question:

What is this rhythm?
- A.
Atrial fibrillation
- B.
Sinus tachycardia
- C.
Sinus rhythm
- D.
Sinus bradycardia
Correct Answer
C. Sinus rhythmExplanation
It's regular; there are P waves, the QRS is normal, the PR interval is normal – sinus rhythm!Rate this question:

- 8.
What is this rhythm?
- A.
Ventricular fibrillation
- B.
Atrial flutter
- C.
Asystole
- D.
Ventricular tachycardia
Correct Answer
D. Ventricular tachycardiaExplanation
This is V-tach. Nothing but huge, scary-looking "tombstone-shaped" waves – about 3 "boxes" high! If this continues, it will become V-Fib.Rate this question:

Anterior
Correct Answer
B. AnteriorExplanation
Anterior MI: ST elevation in leads V1-V4.Rate this question:
-
- 10.

- A.
Inferior
- B.
Anterior
Correct Answer
A. InferiorExplanation
Inferior MI: ST elevation in leads II, III, and aVF.Rate this question:

Treatment for atrial fibrillation/atrial flutter may include which of the following? Select all that apply.
- A.
Blood thinners
- B.
Nitroglycerin
- C.
Beta-blockers
- D.
Calcium channel blockers
- E.
Digoxin
- F.
Norepinephrine
- G.
Amiodarone
- H.
Tambicor
- I.
Cardioversion
Correct Answer(s)
A. Blood thinners
C. Beta-blockers
D. Calcium channel blockers
E. Digoxin
G. Amiodarone
H. Tambicor
I. CardioversionExplanation
The main treatments for atrial fib/flutter include three meds: anticoagulants, rate controllers, and rhythm controllers. If the patient doesn't respond – or if they become more symptomatic, cardioversion is used.Rate this question:
-
- 12.
First-line treatment of ventricular fibrillation is:
- A.
Digoxin
- B.
IV fluid bolus
- C.
Defibrillation
- D.
Cardioversion
Correct Answer
C. DefibrillationExplanation
You "defib" V-Fib!Rate this question:

Treatment for a conscious, asymptomatic patient with ventricular tachycardia could include which of the following? (Select all that apply).
- A.
Defibrillation
- B.
Cardioversion
- C.
Procainamide
- D.
Lidocaine
- E.
Amiodarone
- F.
Beta-blockers
- G.
Calcium channel blockers
- H.
Digoxin
Correct Answer(s)
C. Procainamide
D. Lidocaine
E. Amiodarone
F. Beta-blockers
G. Calcium channel blockersExplanation
You need rate controllers and rhythm controllers. They are asymptomatic, so no cardioversion is needed yet.Rate this question:

- 14.
When the patient with ventricular tachycardia becomes symptomatic but still has a pulse, which treatment is appropriate?
- A.
Defibrillation
- B.
Cardioversion
Correct Answer
B. CardioversionExplanation
When they become symptomatic – and still have a pulse – you try cardioversion.Rate this question:
-
- 15.
Your patient remains in ventricular tachycardia – and loses their pulse. What needs to be done?
- A.
Defibrillation
- B.
Cardioversion
Correct Answer
A. DefibrillationExplanation
If there’s no pulse, you can’t cardiovert – you need to defib!Rate this question:
-
- 16.

Hypocalcemia
- B.
Hypoglycemia
- C.
Hyperkalemia
