The Cardiac Cycle David Taylor

 When you have worked through this you should be able to  Describe the changes in pressure and volume in the left side of the heart during a heat beat.  Recognise and explain the jugular pulse  Explain how they relate to the ECG  Understand the reasons for the first, second and third hear sounds.  Revise concepts of preload, afterload and contractility The cardiac cycle

 There is a video to support this lecture (which you should study before the lecture!)   It is also available with all my other lectures on my website  In the text books: Chapter 18, p. 203 in Preston and Wilson (2013) Chapter 11, p.523 in Naish and Court (2014) Video
