    Holter monitoring of heart electrical activity is useful but prone to artefacts. These signal interferences can mimic heart conditions, complicating analysis and potentially leading to misdiagnosis and incorrect treatment.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Medical Diagnostics

    Context:

    • Continuous electrocardiography (ECG) using the Holter method is vital for assessing cardiac electrical activity.
    • Interpretation challenges arise from artifacts that can obscure or mimic cardiac arrhythmias and blocks.

    Purpose:

    • To describe principal artifacts encountered in Holter ECG recordings.
    • To explain the origins of these artifacts, including patient preparation and equipment faults.
    • To highlight the impact of artifacts on automated analysis and the necessity of expert review.

    Summary:

    • Artifacts in Holter ECG can mimic arrhythmias, blockages, and deform ventricular depolarization, complicating accurate diagnosis.
    • Common causes include inadequate patient preparation, electrode issues, and mechanical or electrical equipment malfunctions.

  • These artifacts limit automated analysis, necessitating experienced visual reinterpretation to prevent diagnostic errors.

    • Impact:

    • Understanding Holter artifacts is crucial for accurate cardiac electrical activity assessment.
    • Minimizing diagnostic errors prevents unnecessary or unjustified therapeutic interventions.
    • Expertise in Holter interpretation enhances the reliability of non-invasive cardiac diagnostics.
