Read the first 6 ECG Patient Monitoring and Safety flashcards as text

  1. What does a delta wave on an ECG indicate?

    Answer: Pre-excitation via an accessory pathway (Wolff-Parkinson-White syndrome)

    A delta wave is a slurred upstroke at the beginning of the QRS caused by ventricular pre-excitation in WPW syndrome.

  2. Which electrolyte abnormality produces tall, peaked T waves on ECG?

    Answer: Hyperkalemia

    Hyperkalemia characteristically produces tall, narrow, peaked T waves, especially in precordial leads.

  3. What does the Osborn wave (J wave) on ECG suggest?

    Answer: Hypothermia

    An Osborn (J) wave is a positive deflection at the J-point and is a hallmark ECG finding in hypothermia.

  4. A patient receiving digoxin shows scooped ST-segment depression on ECG. What is this called?

    Answer: Digitalis effect

    The scooped or 'Salvador Dali mustache' ST depression is the classic digitalis effect, a predictable pharmacologic ECG change.

  5. What ECG pattern is associated with acute pulmonary embolism?

    Answer: S1Q3T3 pattern (S wave in I, Q wave and T-wave inversion in III)

    The S1Q3T3 pattern reflects right heart strain from acute PE, though sinus tachycardia is the most common PE ECG finding.

  6. How should an ECG technician respond if a patient reports chest pain during the ECG recording?

    Answer: Complete the recording immediately, document the symptom, and notify the supervising clinician

    Completing the ECG during active symptoms captures potentially diagnostic changes; notifying a clinician ensures timely evaluation.
