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).
Stone2 states that jumping from 150 feet (46 metres) or higher on land, and 250 feet (76 metres) or more on water, is 95% to 98% fatal. 150 feet/46 metres, equates to roughly 10 to 15 stories in a building, depending on the height of one story. 250 feet is the height of the Golden Gate Bridge in San Francisco. Ideally, anyone jumping on land should try and land on their head, as this maximises the chances of fatal head injuries.
