U Waves

The U wave is a smaller structure after the T wave that resembles a second T wave, kind of like Baby Mario, M&M’s Minis or Pichu. It’s best seen in V2 and V3.

Prominent U waves are most commonly found in:

  • Bradycardia
  • Hypokalaemia

Inverted U waves are abnormal and point to cardiac disease.
