Cardiac arrest in the perioperative period is distinct from cardiac arrest in other scenarios, given that the event is typically witnessed and real-time vital signs are often being monitored. Additionally, having a mental framework by which to consider and refine the differential diagnosis is paramount, as this then guides the selection of a suitable treatment plan. However, in order to establish the correct diagnosis, one must have an adequate understanding of normal cardiac physiology, of cardiovascular pathology, and the ways in which this may adversely affect cardiac function. This chapter provides an overview of how to approach the patient with cardiovascular instability. Subsequent chapters in this section discuss specific treatment plans for the major life-threatening pathophysiologies one could encounter.
