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
