Out of hospital survival rates (even with emergency intervention) are less than 2%. Causes. The Hâs and Tâs of ACLS [1] is a mnemonic used to help recall the major contributing factors to a pulseless cardiac arrest including PEA, Asystole, Ventricular Fibrillation, and Ventricular Tachycardia. The Hâs include: Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hyper/hypokalemia, Hypoglycemia, Hypothermia.
