    Left bundle branch block (LBBB) can mimic heart attacks. T-wave inversions during normal conduction may falsely suggest anteroseptal infarction, but are not indicative of myocardial infarction.

    Area of Science:

    • Cardiology
    • Electrocardiography
    • Diagnostic Imaging

    Background:

    • Intermittent left bundle branch block (LBBB) is a condition affecting cardiac electrical conduction.
    • Electrocardiogram (ECG) abnormalities can sometimes be misleading in diagnosing cardiac events.

    Observation:

    • A 70-year-old woman presented with intermittent LBBB.
    • During periods of normal conduction, her ECG showed T-wave inversions in leads V1-V3.
    • These ECG changes suggested an anteroseptal myocardial infarction.

    Findings:

    • Despite ECG findings suggestive of infarction, the patient was asymptomatic.
    • Serum cardiac enzymes, technetium 99m pyrophosphate, and thallium 201 scans were all negative for myocardial infarction.
    • The LBBB itself can cause T-wave inversions in right precordial leads during normal conduction phases.

    Implications:

    • Left bundle branch block can mimic acute myocardial infarction on ECG.
    • It is crucial to consider LBBB as a potential cause of T-wave inversions to avoid misdiagnosis.
    • This highlights the importance of integrating clinical presentation and multiple diagnostic tests for accurate cardiac assessment.
