  1. Take out the worksheet from yesterday Grab a new worksheet from the front

  2. Your heartbeat can be heard as a “Lub-dub” sound. The first heart sound (Lub) is caused by the mitral and tricuspid valves closing. The second heart sound (dub) is caused by the aortic and pulmonic valves closing.

  3. Heart Murmurs • Sounds like a swishing sound with the Lub dub sound. • Caused by a valve not closing tightly or a hole in the heart

  5. Cardiac Arrest • When circulation completely stops to the rest of the blood • There is no pulse because the heart is not pumping blood • A person becomes unconscious because oxygen is not delivered to the brain • Drug overdosing can cause someone to go into cardiac arrest

  6. Heart Attacks • This is different than cardiac arrest • A heart attack occurs when a blood vessel becomes blocked and interrupts blood flow to the heart, causing heart muscle to die. • a fatty material called plaque (plak) builds up over many years on the inside walls of the coronary arteries

  7. Enlarged Heart • Chicago Bears player, Gaines Adams died last weekend from an enlarged heart • Enlarged heart tells you that the heart is being overworked. • This can mean there is something wrong with the heart anatomically • Or there is too much physical pressure on the heart

  8. Heart Disease • Heart Disease is the leading cause of death in the United States. Every 34 seconds, someone dies of heart disease in the US. Heart disease is a term used to describe many diseases that affect the heart.

  9. Coronary Artery Disease • Disease that causes clogged arteries. • Symptoms: Chest pain and heart attacks

  10. Cardiovascular disease • A number of diseases that affect the heart or blood vessels. These include diabetes, high blood pressure and high cholesterol.

  11. Congestive Heart Failure • A condition that can result from any structural or functional cardiac disorder that impairs the ability of the heart to fill with or pump a sufficient amount of blood throughout the body. • Leads to the heart and body's failure.

  12. Heart Bypass Surgery is used to treat patients with chest pain and prevent heart attacks. In this procedure, part of a blood vessel from another part of the body is stitched in to “bypass” the clogged artery and take blood to the heart.
