  • See Also
  1. T Wave
  • Definitions
  1. Juvenile T Wave
    1. T Wave Inversion is normal in V1-V3 in age <16 years (athletes and non-athletes)
  2. Persistent Juvenile T Wave
    1. T Wave Inversion in anterior and right sided leads (V1-V3) that persists into adulthood
  • Epidemiology
  1. Age: <16 years typically (unless persistent)
  2. Gender (Persistent Juvenile T Waves)
    1. Women may have Juvenile T Waves (inverted V1-3) that persist beyond age 40
    2. Persistent Juvenile T Waves beyond childhood are rare in males
  3. Race and Ethnicity (Persistent Juvenile T Waves)
    1. Persistent Juvenile T Waves are more common in african descent
  • Physiology
  1. Right ventricular predominance in children results in right sided T Wave Inversion (V1-3)
  2. With age, left ventricle thickens and anterior T Waves become upright
  • Findings
  • Juvenile T Waves
  1. Normal findings
    1. T Wave Inversion in V1-V3 (may affect V4 in some cases, depending on lead placement)
    2. Shallow T Wave Inversions (<3 mm deep)
    3. Asymmetric inverted T Wave shape
      1. Gradual downstroke
      2. Abrupt upstroke
  2. Abnomal findings (not consistent with Juvenile T Waves)
    1. T Wave Inversion is NOT attributed to juvenile pattern if V5-6 are affected
    2. Deep inverted T Waves >3mm
    3. Symmetric T Wave appearance (consider Myocardial Ischemia or Wellens Syndrome)
  • Differential Diagnosis
  1. See T Wave Inversion
  2. Benign Persistent Juvenile T Waves
  3. Anterior Myocardial Ischemia
  4. Proximal Left Anterior Descending Occlusion
    1. See Wellen's Syndrome
    2. Deeply inverted T Waves or biphasic T Waves in V2-3
  5. Posterior Myocardial Infarction
  6. Pulmonary Embolism with right heart strain
  7. Right Bundle Branch Block
  8. Right Ventricular Hypertrophy
  9. Brugada Syndrome
  10. Arrhythmogenic Right Ventricular Dysplasia (ARVD)
  11. Brugade Syndrome
  12. Neurogenic T Waves
    1. Precedes ischemic cerebrovascular event
  13. Yamaguchi Syndrome
    1. Hypertrophic Cardiomyopathy involving the cardiac apex
  14. Hypokalemia
    1. Biphasic T Wave in mid-precordial leads
    2. Mattu (2017) Crit Dec Emerg Med 31(3): 11
  • Management
  1. Compare current EKG with older EKGs
  2. Correlate EKG with presenting symptoms (e.g. Chest Pain, Dyspnea)
