Repolarization can be influenced by many factors, including electrolyte shifts, ischemia, structural heart disease (cardiomyopathy) and (recent) arrhythmias. Although T/U wave abnormalities are rarely specific for one disease, it can be useful to know which conditions can change repolarization.

  • Early repolarization (normal variant)
  • Juvenile T waves (normal variant)
  • Nonspecific abnormality, ST segment and/or T wave
  • ST and/or T wave suggests ischemia
  • ST suggests injury
  • ST suggests ventricular aneurysm
  • Q-T interval prolonged
  • Prominent U waves
  • Cardiac Memory|Cardiac Memory
