This video discusses the 6 subphases of systole and distole of the cardiac cycle including 1. systole: isovolumic contraction, 2. systole: ejection, 3. diastole: isovolumic relaxation, 4. diastole: rapid inflow, 5. diastole: diastasis, 6. diastole: atrial systole.
A graph showing pressure change differences between the atria, ventricle, and aorta is included. These pressure changes are correlated with volume changes in the ventricle, as well as with the EKG and 1st, 2nd, and 3rd heart sounds.
Ten questions to assess understanding are included at the end of the video.
This is a lot of information so you may want to watch more than once.
