  1. A patient's monitor alarm triggers for a heart rate of 42 bpm with narrow QRS complexes and visible P waves before each QRS. What rhythm does this most likely represent?

    Answer: Sinus bradycardia

    A slow rate with a consistent 1:1 P-to-QRS relationship and narrow complexes indicates sinus bradycardia, where the SA node is simply firing slowly.

  2. Which ECG pattern is associated with Wolff-Parkinson-White (WPW) syndrome during normal sinus rhythm?

    Answer: Short PR interval and delta wave

    WPW is identified by a short PR interval (<0.12 s) and a delta wave (slurred upstroke of the QRS) caused by ventricular pre-excitation via an accessory pathway.

  3. The cardiothoracic technician notices ST elevation in leads V1–V4 with reciprocal depression in II, III, and aVF. Which coronary artery is most likely occluded?

    Answer: Left anterior descending artery (LAD)

    The LAD supplies the anterior wall and septum; its occlusion causes ST elevation in precordial leads V1–V4 with reciprocal inferior changes.

  4. When a patient's transcutaneous pacemaker is capturing at 70 bpm but the patient's pulse is absent, the most appropriate next action is:

    Answer: Resume CPR immediately as pacemaker capture alone does not ensure perfusion

    Electrical capture on the monitor does not guarantee mechanical contraction; the absence of a pulse means CPR must continue while the underlying cause is treated.

  5. Hyperkalemia most commonly produces which ECG change as an early sign?

    Answer: Tall peaked T waves

    Elevated potassium first manifests as tall, narrow, peaked (tent-like) T waves before progressing to PR prolongation, wide QRS, and sine wave pattern.

  6. What does a negative QRS deflection in lead I combined with a positive QRS in lead aVF indicate about the cardiac axis?

    Answer: Right axis deviation

    A negative QRS in lead I and positive QRS in aVF places the electrical axis in the right axis deviation range (between +90° and +180°).

  7. A patient with an implanted pacemaker shows pacemaker spikes on the monitor but no following QRS complex. This finding is called:

    Answer: Failure to capture

    Failure to capture occurs when the pacemaker delivers an electrical impulse that does not depolarize the myocardium, resulting in a spike without a subsequent QRS.
