    Area of Science:

    • Biomedical Engineering
    • Cardiology
    • Neurology

    Background:

    • Electrocardiogram (ECG) interpretation can be challenging due to artifacts.
    • Common artifact sources include body movement, poor electrode contact, and electromagnetic interference.
    • Implantable electronic devices are increasingly recognized as a source of ECG artifacts.

    Observation:

    • A novel implanted tremor control device is used for patients with essential or Parkinsonian tremors.
    • This device, designed for tremor suppression, has been observed to generate distinct ECG artifact patterns.
    • Previous reports identified ECG artifacts from nerve and spinal cord stimulators.

    Findings:

    • The study reports a specific, differential pattern of ECG artifacts associated with the use of an implanted tremor control device.
    • These artifacts differ from those typically seen with other implantable devices.
    • Understanding these unique patterns is crucial for accurate ECG analysis.

    Implications:

    • Accurate ECG interpretation is vital for patient diagnosis and management.
    • Clinicians must be aware of potential artifacts from newer implantable devices like tremor controllers.
    • Recognizing device-specific artifacts can prevent misdiagnosis and ensure appropriate patient care.
