  1. Which lead views the heart from the left arm to the left leg?

    Answer: Lead III

    Lead III measures the electrical difference between the left arm and left leg electrodes.

  2. A rhythm that is regular with a rate over 100 bpm originating from the SA node is called:

    Answer: Sinus tachycardia

    Sinus tachycardia is a normal-appearing rhythm from the SA node exceeding 100 bpm.

  3. In lead placement, the V6 electrode is positioned at the:

    Answer: Midaxillary line at the same level as V4

    V6 sits in the midaxillary line, horizontally in line with V4 and V5.

  4. Which of the following is an augmented (unipolar) limb lead?

    Answer: aVF

    aVF, along with aVR and aVL, are the augmented unipolar limb leads.

  5. If a patient has a tremor, the resulting ECG artifact is best described as:

    Answer: Somatic (muscle) tremor artifact

    Involuntary muscle activity from tremor creates a somatic tremor artifact on the tracing.

  6. The QT interval represents the total time for:

    Answer: Ventricular depolarization and repolarization

    The QT interval spans from the start of the QRS to the end of the T wave, covering ventricular activity.

  7. A heart rate below 60 bpm with a normal sinus origin is termed:

    Answer: Sinus bradycardia

    Sinus bradycardia is a sinus-origin rhythm with a rate under 60 beats per minute.
