  5. Findings: LVH with Repolarization Abnormality (or Strain Pattern)
    1. Precautions
      1. LVH with Repolarization Abnormality may be confused with acute Myocardial Infarction
      2. Always exclude Acute Coronary Syndrome
      3. Compare old Electrocardiograms
    2. Asymmetric T Wave Inversion
      1. Leads I, aVL, V4, V5, V6
    3. ST segment Depression (mild)
      1. Leads I, aVL, V4, V5, V6

Electrocardiogram: left ventricle hypertrophy (finding) (C0232306)

Definition (NCI_CDISC) An electrocardiographic finding suggestive of a hypertrophied left ventricle, characterized by large QRS amplitudes and secondary findings of left atrial enlargement, left axis deviation, or typical pattern of ST depression and T wave inversion.
