    2 The condition, current treatments and procedure

    The condition

    2.1 Cardiac arrest is when normal blood circulation suddenly stops because the heart fails to contract effectively. The underlying abnormal cardiac rhythms most commonly associated with cardiac arrest are ventricular fibrillation (VF), asystole, pulseless electrical activity, and pulseless ventricular tachycardia (VT). It leads to loss of consciousness, respiratory failure and, ultimately, death.
