    Study Notes

    Electrocardiogram (ECG or EKG) Overview

    • An ECG records the heart's electrical impulses via electrodes and a galvanometer.
    • Electrodes are placed on arms, legs, and chest to capture electrical activity.
    • Standard ECG comprises 12 leads: six limb leads (I, II, III, AVF, AVL, AVR) and six precordial leads (V1-V6).

    Electrical Activity of the Heart

    • The sinoatrial (SA) node initiates electrical impulses, leading to atrial contraction (depolarization).
    • Impulses travel to the atrioventricular (AV) node and the bundle of His, causing ventricular contraction.
    • The heart's recovery phase involves repolarization, reflected in ECG waves and complexes:
      • P wave: atrial depolarization
      • QRS complex: ventricular depolarization
      • ST segment, T wave, and U wave: ventricular repolarization

    ECG Wave Characteristics

    • P Wave: Normal duration is 0.12 seconds; changes may indicate atrial enlargement.
    • PR Interval: Normal duration is 0.2 seconds; prolonged intervals may suggest AV conduction delay.
    • QRS Complex: Normal duration is less than 0.12 seconds; enlargement suggests myocardial infarction or hypertrophy.
    • ST Segment: Depressed segment indicates ischemia; elevated may signify myocardial infarction.
    • T Wave: Inverted T wave can indicate ischemia; peaked T waves may indicate hyperkalemia.

    Factors Affecting ECG Results

    • Body movement and electromagnetic interference can distort results.
    • Poor electrode contact with skin can lead to inaccurate readings.

    Clinical Problems Identified by ECG

    • Can detect dysrhythmias, hypertrophies, ischemia, electrolyte imbalances, and infarction.

    Nursing Implications

    • Document all medications the client is taking to correlate with ECG findings.
    • Ensure the client relaxes and breathes normally during the ECG for accurate readings.

    Purpose of ECG

    • Identifies rhythm disturbances and assesses heart chamber size and position.
    • Aids in diagnosing conditions like myocardial infarction (MI) and pericarditis.
    • Evaluates medication effects and artificial pacemaker function.

    Equipment Required

    • ECG machine, ECG paper, electrodes with gel, and gauze pads or alcohol cotton balls.

    Assessment Steps

    • Review medical history and assess cardiac status.
    • Prevent electrical interference during the procedure.
    • Properly attach limb and precordial electrodes following standardized placements.

    ECG Recording Procedure

    • Set ECG machine to standard speed of 25 mm/second and full voltage.
    • Instruct the patient to remain still and avoid talking during recording.
    • Press AUTO to begin recording the 12-lead ECG; observe waveform quality and adjust as needed.
    • Label ECG trace with patient information and document response during the recording.

    Post-Procedure Care

    • Remove electrodes, clean skin if necessary, and dispose of electrodes properly.
    • Ensure the patient is comfortable post-procedure, adjusting the bed as needed.
    • Maintain hygiene protocols and document findings in the patient's chart.
