9. Discovery • The problem ... • How many people die of heart failure per year? • How many people have irregular heart beats? (Arrhythmia) • What are the consequences of this disease? • Lost productivity • Cost of medicine • Cost of hospital care Mr. Bittarelli and Mr. Galinato March 2005

10. Discovery • What tools, books, models and web sites can you find that explain how the heart works.? Look for clear, concise, memorable examples. • We want to develop a model that is different than heart education materials developed by others. • Reference Websites: • http://www.pbs.org/wgbh/nova/heart/ • http://sln.fi.edu/biosci/systems/circulation.html • http://www.heartcenteronline.com Mr. Bittarelli and Mr. Galinato March 2005

11. Discovery • How does the heart work? Mr. Bittarelli and Mr. Galinato March 2005

12. Discovery • How does the heart work? • The heart has two pumps. • The right blue pump takes tired blood from the body and sends it to the lungs. • The left red pump takes fresh blood from the lungs and sends it back to the body. • When the heart is working normally, it beats between 60 – 80 times per minute. In our model, select, ‘Healthy Heart’ and the microprocessor controls the pumps to simulate a normal heart rhythm. • When the heart has a common problem, arrhythmia, it beats irregularly making it harder to get fresh, oxygenated blood to the body. In our model, select, ‘Irregular Heart Beat.’ Now the microprocessor controls the pumps to pump irregularly. • One way of treating arrhythmia is to insert a pacemaker which tells the heart when to pump. In our model, select ‘Pacemaker’ and the heart stops until the pacemaker microprocessor is turned on. The 2nd pacemaker microprocessor tells the 1st microprocessor to pump one cycle only when it gets an infrared signal. The 2nd pacemaker microprocessor lights up and beeps each time it sends a signal. You can see the pumps beat one cycle each time the pacemaker beeps. Mr. Bittarelli and Mr. Galinato March 2005
