  1. The Heart of the matter! Jodi McWhirter RN, BSN Northwest Children’s Heart Care

  2. The Pump • Everyone knows that the heart is a vital organ. We cannot live without it. • However when you get right down to it, your heart is just a pump. As with all other pumps it can be made wrong, get clogged, and even break down.

  3. The Heart • The heart is a hollow cone shaped muscle, located between the lungs and behind the sternum. • 2/3’s of the heart is located to the left of the midline of the body, 1/3 is to the right.

  4. Chambers and Valves • The heart is divided into 4 chambers and each chamber has a one way valve at it’s exit that prevents blood from flowing backwards. • When the heart muscle contracts or beats (called systole), it pumps blood out of the heart. The heart contracts in two stages. In the first stage, the right and left atria contract together, pumping the blood to the right and left ventricles. Then the ventricles contract together to propel blood out of the heart. Then the heart relaxes before the next heartbeat allowing the heart to fill up again.

  5. Blood Flow • Blood enters the right atrium (1.upper ½ of body & 2. lower ½ of body) • When 3 contracts, blood goes through 4 into 5. • When 5 contracts blood goes through 6 into 7 and turns red. • After the lungs blood returns through 8 into 9. • When 9 contracts blood travels through 10 into 11. • When 11 contracts blood goes through 12 into 13 and then to the body.

  6. Electricity • The heart has cells that generate electrical activity on their own. • These cells leak charged particles into the pathway which produces an electrical impulse that spreads across your heart, causing it to contract. • This happens more than once per second to produce a normal heart beat of 72 beats per minute. • The electricity at the SA node causes the right and left atria to squeeze and the ventricles to fill. • The electrical impulse then travels down to the Purkunje fibers and causes the right and left ventricle to contract.

  7. ECG • Electrocardiogram is used in the diagnosis process and to achieve a baseline.

  8. Echocardiogram • Echo uses sound waves to create a moving picture of the heart. • The picture is much more detailed than an Xray without radiation. • A person trained in this is called a sonographer.
