Synonymes: Vertex sharp transient or V wave

• Maximum at the vertex (like K complex)
• Amplitude: 50-150 microV
• Presence in non-REM 1 and to a lesser extent in non-REM 2
• Narrower and more focal than K complex
• Unlike K complex vertex waves are not associated with sleep spindles
• In children and young adult vertex waves could be sharp and in a repetitive run, not to be confused with an epileptic discharge.
