Introduction to Electrocardiography Name _______________________________ Date _______________________Pd_______ EKG or ECG stands for electrocardiogram, a test that records the electrical activity of the heart. The test is performed by placing electrodes on the skin which can detect the heart?s electrical impulses. The electrocardiograph that is produced by the test can indicate a variety of heart function irregularities. Do some research to determine what is taking place in the heart to produce the following waves on an EKG tracing. P wave: QRS complex: T wave: Each line on the x-axis of the graph represents 0.04 seconds. The normal ranges for the PR Interval and QRS Interval are listed below. Determine if this EKG represents a normal test for these waves.

DOUBLE CIRCULATION IN MAMMALS OBJECTIVE ? Describe how the structure of the heart supports its function (blood pressure, force of contraction) ? Describe the flow of blood to and from the heart via the associated blood vessels CARDIOVASCULAR SYSTEM heart?arteries?arterioles ? ? veins?venules?capillaries HUMAN HEART ? 4 chambers(2 upper chamber, 2 lower chamber) ? Upper chambers are called atria ? Lower chambers are called ventricle ? Right side of the heart is separated from the left by a septum. ? This prevents the mixing of deoxygenated blood and oxygenated blood. HUMAN HEART RIGHT SIDE OF THE HEART 1. Right atrium ? BLOOD LOW IN OXYGEN(HIGH IN CARBON DIOXIDE) FROM ALL PARTS OF THE BODY RETURNS TO THE ATRIUM

EMI Huang: First third of NED CIRC NOTES 2009 Systole: Heart ventricles contract/chamber pump Diastole: Heart ventricles relax/chamber fills AIM: What are the parts of the heart and blood? William Harvey established direction of blood flow and elucidated difference between pulmo and systemic circulation. TYPES OF CIRCULATION: Pulmonary: travel of blood between heart and lungs Coronary: supplies blood to heart Renal: supplies blood to kidneys Hepatic portal: supplies liver with nutrients; receive oxygenated blood from the aorta HEART: CHAMBERS AND VALVES Atria: blood into upper chambers Ventricles: blood out of lower chambers. Valves/regulated one-way flow. A/V: Atria Ventricular S/L: Semilunar (Valves separate chambers, preventing blood from mixing)

The Circulatory System Types of circulation: Gastrovascular cavities- Digests and distributes nutrients throughout the body of hydras and cnidarians. Open circulatory system- Blood and interstitial fluid are separated. This fluid is called hemolymph. The heart(s) pump hemolymph into sinuses where chemical exchange occurs between hemolymph and body cells. Open circulatory systems are in insects and arthropods. Advantages of an open circulatory system are less energy costly because of their low hydrostatic pressures and need less energy to maintain because they have no blood vessels.
