1. What is the normal resting heart rate for an adult?
A. 40–60 bpm
✓ B. 60–100 bpm
C. 100–120 bpm
D. 120–160 bpm
Explanation:
A normal adult resting heart rate is 60–100 beats per
minute. Rates below or above this may indicate bradycardia
or tachycardia respectively.
,2. Which ECG wave represents ventricular depolarization?
A. P wave
B. T wave
✓ C. QRS complex
D. U wave
Explanation:
The QRS complex reflects ventricular depolarization, which
leads to ventricular contraction.
3. Atrial fibrillation is characterized by:
A. Regular rhythm with sawtooth waves
✓ B. Irregularly irregular rhythm
C. Wide QRS complexes
D. Bradycardia with U waves
Explanation:
,Atrial fibrillation shows an irregularly irregular rhythm with
no distinct P waves due to chaotic atrial activity.
4. First-line treatment for unstable ventricular tachycardia
is:
A. Amiodarone
B. Adenosine
✓ C. Synchronized cardioversion
D. Atropine
Explanation:
Unstable VT requires immediate synchronized cardioversion
to restore perfusion.
5. Which drug is used for symptomatic bradycardia?
A. Lidocaine
✓ B. Atropine
C. Dopamine antagonist
D. Verapamil
, Explanation:
Atropine increases heart rate by blocking parasympathetic
stimulation.
6. Sinus bradycardia is defined as:
A. HR > 100 bpm
✓ B. HR < 60 bpm
C. Irregular rhythm
D. No QRS complexes
Explanation:
Sinus bradycardia occurs when the heart rate is below 60
bpm with normal conduction.
7. Which rhythm is life-threatening and requires immediate
defibrillation?
A. Atrial flutter
B. Sinus tachycardia
