This video presents the concepts of preload and afterload. Both of these concepts are important to understand to assess the performance of the heart. Sarcomere structure function and its relationship to preload and afterload is also discussed. We will also discuss the difference between the passive tension and active tension. Notice that cardiac performance is assessed by: Heart rate Conduction velocity Preload Afterload Contractility

In this video we will learn about :

1. Sarcomere structure and function.

2. Sarcomere length - tension relationship.

3. Frank starling law. 

4. Preload and force of contraction 

5. After load and velocity of contraction.
