Short QT


  • Clinically important due to potential to cause atrial and ventricular tachycardias, syncope, and sudden cardiac arrest


Clinical features

  • Syncope
  • Cardiac arrest
  • Palpitations
  • ECG findings:
    • QTc < 360 (males) or <370 (females)
    • In congenital short QT, also have:
      • Lack of normal QT changes with HR
      • Peaked T waves (especially in precordial leads)
      • Short or absent ST segments
      • +/- early repolarization


  • Evaluate for and treat underlying causes
  • Congenital short QT: refer to cardiology, may need ICD
