  1. A rhythm strip shows no identifiable P waves, an irregularly irregular ventricular response, and a rate of 110 bpm. What rhythm is this?

    Answer: Atrial fibrillation with rapid ventricular response

    Atrial fibrillation with rapid ventricular response presents with an irregularly irregular rhythm, absent distinct P waves, and a ventricular rate above 100 bpm.

  2. Which ECG finding indicates ventricular fibrillation?

    Answer: Chaotic, undulating baseline with no identifiable QRS complexes

    Ventricular fibrillation produces a chaotic, disorganized baseline with no discernible P waves, QRS complexes, or T waves.

  3. On a 12-lead ECG, ST-segment elevation in leads II, III, and aVF most suggests injury to which territory?

    Answer: Inferior wall

    Leads II, III, and aVF are the inferior leads; ST elevation in these leads indicates inferior wall myocardial injury.

  4. A patient's rhythm strip shows regular P waves at 80 bpm, but only every other P wave is followed by a QRS. What is this rhythm?

    Answer: Second-degree AV block, Mobitz Type II with 2:1 conduction

    A 2:1 AV block means every other P wave conducts to the ventricles, which is consistent with Mobitz Type II presenting with 2:1 conduction.

  5. Which characteristic best distinguishes ventricular tachycardia (VT) from supraventricular tachycardia (SVT) with aberrant conduction on an ECG?

    Answer: AV dissociation (independent P waves and QRS complexes)

    AV dissociation, where P waves and QRS complexes are independent, is a hallmark of ventricular tachycardia and helps differentiate it from SVT with aberrancy.

  6. A patient with a pacemaker shows occasional QRS complexes not preceded by a pacemaker spike, yet the pacemaker appears to function normally otherwise. This is most consistent with:

    Answer: Normal demand pacemaker function with intrinsic beats

    A demand pacemaker senses intrinsic beats and inhibits its own output; native QRS complexes without pacemaker spikes reflect normal sensing and inhibition.

  7. Before applying ECG electrodes, the skin should be prepared by:

    Answer: Clipping hair, lightly abrading, and cleaning with alcohol

    Proper skin preparation—removing hair, light abrasion, and alcohol cleaning—reduces impedance and improves signal quality.
