Your department has asked you to prepare a talk about Cardiac Muscle and Electrical Activity based on this week’s learning activities. Knowing that your audience’s attention will diminish over time, you want to cover the most important information first. What are the top ten specific items you would cover, with number one being the most important? Provide a rationale for each item explaining why it should be covered and why it appears in the position you have chosen. The videos may help, but include one reference from an outside source. Copy and paste the URL and videos will come up.
