Transesophageal (tranz-ih-sof-uh-JEE-ul) echocardiography (EK-o-kar-de-OG-rah-fee), or TEE, is a test that uses sound waves to create high-quality moving pictures of the heart and its blood vessels. TEE is a type of echocardiography (echo). Echo shows the size and shape of the heart and how well the heart chambers and valves are working. Echo can pinpoint areas of heart muscle that aren't contracting well because of poor blood flow or injury from a previous heart attack.
Grand Prix: The highest level of show jumping. Run under International Federation for Equestrian Sports (FEI) rules, the horse jumps a course of 10 to 16 obstacles, with heights and spreads of up to 6.5 feet (2.0 m).
Hurdle to two feet. A hurdle to two feet is used on vault and any two-foot takeoff into a forward salto (flip or roll) skill. The general concepts of this hurdle are the same as other hurdles. Keep the steps and body positioning. This hurdle does not involve a skip; instead, it is a long low jump from one foot to two.
