Causes of pulseless electrical activity (mnemonic)

Pulseless electrical activity is a very disconcerting medical scenario with a very high mortality unless its aetiology can be quickly ascertained and corrected. A mnemonic to remember the different causes of pulseless electrical activity is:

  • MAD (triple H) CAT


  • H: hypoxia/hypothermia
  • H: hypovolaemia
  • H: hypokalaemia/hyperkalaemia

A useful way to remember the mnemonic is recalling Triple H is one of the biggest WWE stars and his "mad cat".
