Indicate the proper order of events during the cardiac cycle by placing numbers in the blanks preceding the events in sequence. (Some steps may have been omitted.) The first event is labeled as your starting point. AV valve open; aortic valve closed; ventricular filling occurring Blood ejected from the ventricles Isovolumetric ventricular relaxation Atrial contraction AV valve opens; ventricular filling occurs again; one cardiac cycle is complete Aortic valve opens SA node discharges Ventricular filling complete Ventricular relaxation begins Aortic valve closes Isovolumetric ventricular contraction Ventricular contraction begins; AV valve closes

Shown below at the top of the image (1-5) is the cardiac cycle in order, starting with atrial systole, and ending with complete cardiac diastole. Match the events that occur on the EKG (and the heart sounds shown below the EKG) with the events of the cardiac cycle. AVs close 3 2 SLs close B Lub Dub
