  1. Which of the following correctly describes the placement of the V4 precordial electrode?

    Answer: 5th intercostal space, midclavicular line

    V4 is placed at the 5th intercostal space at the midclavicular line, serving as a transition point between septal and lateral precordial leads.

  2. An ECG shows a ventricular rate of 150 bpm with a sawtooth baseline pattern and 2:1 conduction. What rhythm is present?

    Answer: Atrial flutter with 2:1 block

    Atrial flutter typically produces a sawtooth (flutter wave) pattern at approximately 300 bpm atrial rate; with 2:1 conduction, the ventricular rate is ~150 bpm.

  3. Which ECG change is most associated with digitalis (digoxin) toxicity?

    Answer: Bidirectional ventricular tachycardia

    Bidirectional ventricular tachycardia, where the QRS axis alternates beat-to-beat, is a classic and serious sign of digitalis toxicity.

  4. What is the correct paper speed for a standard 12-lead ECG recording?

    Answer: 25 mm/sec

    The standard ECG paper speed is 25 mm/sec, which allows accurate measurement of intervals and comparison across recordings.

  5. A right bundle branch block (RBBB) pattern on ECG is best identified by which finding?

    Answer: Wide QRS with rSR' (rabbit ear) pattern in V1 and wide S wave in lateral leads

    RBBB produces a wide QRS (≥0.12 s) with an rSR' or RSR' pattern (rabbit ears) in V1 and broad, slurred S waves in leads I, V5, and V6.

  6. Which condition can cause electrical alternans on the ECG?

    Answer: Cardiac tamponade

    Electrical alternans — beat-to-beat alternation in QRS amplitude — is a classic ECG sign of cardiac tamponade due to the heart swinging within a large pericardial effusion.

  7. When recording a 12-lead ECG, which action should the CCT take if baseline wander is observed?

    Answer: Ask the patient to hold their breath and apply a low-frequency filter

    Baseline wander from respiratory movement can be reduced by asking the patient to hold their breath briefly and applying a low-frequency (baseline) filter.
