Heart Anatomy

Blood Flow: On your Exam

Electrocardiogram EKG Electrical events of the heart rhythm viewed as a wave -> Write-> this down! ->->->->->->

Blood Vessels

Common Tests Electrocardiography: record the electrical activity (EKG) Radiography: x rays Angiography: radiographic study of the blood vessels following an injection of contrasting dye material

Common Procedures Angioplasty: surgical repair of blood vessel Defibrillation: use of electrical shock to restore the normal Transfusion: introduction of new blood or blood components into the blood stream

Common Ailments: Cardiovascular System Aneurysm: localized balloon-like enlargement of an artery Atherosclerosis: hardening/ narrowing of arteries due to plague build up Cardiomyopathy: disease of the heart muscle

Activities Outline the blood flow through the heart Indicate when blood is oxygenated (blue) and not (red) Arrows for direction if you do a picture Draw an EKG (normal) Know what abnormal EKGs look like (probably should draw them), and what the abnormalities are called (in your book!) Dpict a NORMAL EKG and explain what the waves/letters indicate
