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

  1. Which AHA monitoring category applies to patients who are in the first 48 hours after acute MI?

    Answer: Class I (monitoring indicated)

    The AHA designates continuous cardiac monitoring as Class I (clearly indicated) during the first 48 hours after acute MI.

  2. What is the recommended ECG lead for detecting ST-segment changes in the anterior wall of the left ventricle?

    Answer: V4 or V5

    V4 and V5 provide the best sensitivity for detecting anterior wall ST changes during ischemia monitoring.

  3. A patient's ECG shows a sudden straight line. What is the FIRST action the nurse should take?

    Answer: Check the patient and verify lead connections before assuming asystole

    A flat line on a monitor most often reflects a loose lead or electrode, not asystole; always assess the patient first.

  4. What does 'signal-averaged ECG' (SAECG) primarily detect?

    Answer: Late potentials indicating risk for ventricular arrhythmias

    SAECG detects ventricular late potentials, which indicate areas of slow conduction predisposing to re-entrant ventricular arrhythmias.

  5. Which condition requires telemetry monitoring according to AHA Class II guidelines?

    Answer: Newly diagnosed heart failure with reduced ejection fraction

    New heart failure with reduced ejection fraction carries risk of arrhythmias, making it an AHA Class II monitoring indication.

  6. What is the purpose of the QTc (corrected QT) interval calculation in monitoring?

    Answer: To adjust QT for heart rate and identify prolongation risk for torsades de pointes

    QTc corrects the QT interval for heart rate, allowing standardized assessment of prolongation risk for fatal arrhythmias.
