Chain of survival is a four link chain used to illustrate the importance of timely actions for the survival of victims of sudden cardiac arrest due to VF.
Ischemic cascade is the temporal sequence of changes due to myocardial ischemia. Ischemic episodes are initiated by a supply - demand mismatch in myocardial oxygen delivery.
