    This case study highlights significant electrocardiogram (ECG) changes in a young student, initially mistaken for serious heart issues. These findings were ultimately attributed to functional changes, specifically early repolarization syndrome with autonomic lability.

    Area of Science:

    • Cardiology
    • Clinical Diagnostics
    • Medical Case Reports

    Background:

    • Electrocardiogram (ECG) interpretation is crucial for diagnosing cardiac conditions.
    • Distinguishing between pathological and functional ECG changes is essential for appropriate patient management.
    • Early repolarization syndrome (ERS) is a common benign finding, but can mimic serious pathology.

    Observation:

    • A 25-year-old African student presented with significant ECG alterations, including ST-elevations and T-negativations in anterolateral leads.
    • These ECG changes occurred in the context of hepatologic diagnostics, despite a healthy heart.
    • The patient exhibited pronounced vegetative lability.

    Findings:

    • The observed ECG abnormalities were diagnosed as functional changes, specifically early repolarization syndrome.

  • The isoproterenol test, a sympathicomimetic challenge, influenced the ECG changes, aiding in diagnosis.
  • The findings suggest a link between autonomic nervous system lability and ECG manifestations.

    • Implications:

    • Correctly identifying and interpreting these functional ECG changes is vital to avoid misdiagnosis and unnecessary interventions.
    • Understanding the role of autonomic lability in ECG presentation can refine diagnostic approaches.
    • This case underscores the importance of considering functional cardiac conditions in young, healthy individuals presenting with abnormal ECG findings.
