Y1 - 2014 N1 - T2 - Anesthesiology Core Review: Part One Basic Exam AB - The cardiac cycle describes a sequence of mechanical and electrical events that cause a cardiac contraction and ejection (ventricular systole), and relaxation or filling (ventricular diastole). In general, a pressure gradient develops between the chambers, which leads to ejection of the stroke volume (SV) and forward flow of blood through the body. Therefore, the cardiac cycle is made up of four main phases: filling phase, isovolumetric contraction, ejection phase, and isovolumetric relaxation (Figure 148-1).
