The cardiac cycle involves four major stages of activity: 1) "Isovolumic relaxation", 2) Inflow, 3) "Isovolumic contraction", 4) "Ejection". (See Wiggers diagram, which presents the stages, label-wise, in 3,4,1,2 order, left-to-right.) Moving from the left along the Wiggers diagram shows the activities within four stages during a single cardiac cycle. (See the consecutive panels labeled, at bottom-right, "Diastole" then "Systole"). Web27 jan. 2024 · About 90% of ventricular filling occurs passively before atrial contraction (Phase 1). Aortic and pulmonary arterial pressures continue to fall during this period. Jump to other phases: Phase 1 - Atrial Contraction. Phase 2 - Isovolumetric Contraction. Phase 3 - Rapid Ejection. Phase 4 - Reduced Ejection. Phase 5 - Isovolumetric Relaxation.
Web26 mrt. 2016 · The eight-tenths of a second that a heart beats is called the cardiac cycle. During that 0.8-second period, your heart forces blood into your blood vessels (for 0.4 seconds) and then takes a quick rest (for just 0.4 seconds). Here’s what … Web5 stages of the cardiac cycle: Atrial systole - atria contract which power blood into the ventricles. The AV valve opens while the semilunar valves close. Early ventricular systole - ventricle contracts, atria unwind, semilunar valves shut. Late ventricular systole - withdrawal of ventricles, atria unwind, blood powers into the pneumonic ...
