However, there are enough subtleties in interpretation that the human element is still a very important part of the assessment. The ECG machine is not always correct. The decision to act upon the results of an ECG depends not only upon the ECG tracing, but also upon the clinical situation.
The Great Victoria Desert is the largest desert region in Australia and the third largest desert in the world. It covers over 160,000 square miles in the south-central portion of the country. In spite of very low annual rainfall amounts, a large number of plant species exist here.
Basin and Range topography characterizes the desert: wide valleys bordered by parallel mountain ranges generally oriented north-south. There are more than 33 peaks within the desert with summits higher than 9,800 feet (3,000 m), but valleys in the region are also high, most with elevations above 3,900 feet (1,200 m).y the time it reaches the east side of the mountains, little moisture is left to bring to the desert. The rain shadow effect is more pronounced closer to the Sierra Nevada, with yearly precipitation in the Great Basin desert averaging 9 inches (230 mm) in the west and 12 inches (300 mm) inches in the east.
