To understand how the test is done it is important to understand how the heart works. When the heart beats, electrical conductivity takes place from the top of the heart to the bottom. This enables the heart to contract and pump blood to the rest of the body. The heart pumps blood with each heart beat and therefore electrical conductivity takes place with each heartbeat. An EKG is usually done to show any abnormalities that may be present in the heart, for example arrhythmias and abnormal heart beats. This is important, so the EKG is the first test that is done on cardiac patients to help in the diagnosis of abnormalities of the heart. The EKG helps to show the speed at which the heart is beating and identify whether it is beating slower or faster than it should. A regular heartbeat is between 60 to 100 beats per minute. When the heart beats less than 60 beats per minute, this is an abnormality called bradycardia and when the heart beats at a speed of more than 100 beats per minute, this is an abnormality called tachycardia. The EKG also helps to assess the heart rhythm, as it shows whether the heartbeats are irregular or steady. It also shows the timing and strength of the heart's electrical conductivity as the impulses pass through the heart with every heartbeat.

summary: Familiarize yourself with how the heart works. Understand what an EKG is used for. Know what the EKG can identify.

The inseam, or length from the top of the inside of your thigh to the cuff, is important when it comes to bootcut jeans, especially for petite or shorter people. You do not want an inseam that is very long, as the jeans will be too long for your legs and you may need to hem off the bootcut portion of the pants to get them to fit. Instead, opt for an inseam that is made for petite people, usually around 29 to 30 inches (74 to 76cm). You may need to still hem the jeans to fit your legs, but with a shorter inseam, you will have to take off less of the bootcut. Bootcut jeans are usually styled with high heeled boots, pumps, or sandals with a heel. Make sure you get a nice long, lean look by getting a pair of bootcut jeans that have an inseam that is 1 to 2 inches (2.5 to 5.1cm) longer than your usual inseam. A longer inseam will ensure the jeans hit 1 inch (2.5cm) above your shoes. If you are petite, opt for a shorter inseam so the jeans sit above your shoes when you wear heels. Cropped bootcut jeans sit 1 to 3 inches (2.5 to 7.6cm) above your ankles, flaring slightly below your knees. They are a fun option if you want to show off a pair of shoes or even a pair of socks with your shoes. This style is very on trend and can be worn by petite or tall people. You may opt for jeans that hit just above your hips if you don't want to feel too constrained or covered up. Maybe you like showing off your stomach and want too much fabric over this area. Keep in mind you may expose your stomach or a bit of skin if you tend to wear crop tops or shorter tops with your jeans. Make sure the low-rise pair fits your hips snugly so you do not have to keep pulling them up when you sit or bend down. Wearing a belt with low-rise jeans can also help you avoid this problem. Mid-rise, where the jeans hit you just above your hips, or high-rise, where the jeans sit just below your belly button, are good if you prefer to keep your stomach area covered. They are also a good option if you want to make your legs look longer and do not have to worry about pulling up your pants when you sit or bend down. Mid-rise and high-rise bootcut jeans are also a good option if you like wearing cropped tops or shorter tops with your jeans and do not want to worry about exposing your stomach. The only way to confirm the jeans fit you properly is to try them on in the store before you buy. Walk around in them, and sit or bend down while wearing them to see how they feel. The inseam should hit you correctly and the waist should not feel too tight or constraining. If you prefer to shop for jeans online, read the measurements for the jeans carefully before you buy. Measure your inseam and waist with measuring tape to ensure the jeans will fit you properly.

summary: Get a pair with a shorter inseam if you are petite. Go for a pair with a longer inseam if you plan to wear heels. Try cropped bootcut jeans for a trendy look. Get a low-rise pair if you prefer less fabric over your stomach. Go for a mid-rise or high-rise pair if you like having more coverage. Try on the jeans before you buy them.

nearest Saturn's current position to use as a guide. When you've gotten a sense of Saturn's path, you'll first need to locate a constellation to use as a focal point to start scanning from. Basically, you want to familiarize yourself with the constellation its closest to and then use a chart of Saturn's position to find out exactly where to look in relation to that star. In 2014, that constellation will be Libra, while in January of 2016, it will be directly North of the Antares star in the constellation Scorpius. You can look at Saturn's path here: http://www.nakedeyeplanets.com/saturn.htm If you're viewing on an oppositional date, aim your telescope due South. Typically, Saturn will appear to have a yellowish-golden hue and won't twinkle like stars do. Because Saturn is a planet, it may not be as bright or instantly noticeable as some stars, because it doesn't shimmer. Use your constellation as a point of reference and look for a color difference. While Saturn itself is visible with the naked eye, it's a shame to try to find it and not be able to enjoy its distinctive rings, which are visible with a basic telescope. Using a telescope will make the job much easier, as Saturn will appear to be a distinctly different shape than other bodies in the sky. If you've got a powerful telescope with a yellow filter, that can help isolate the particular light in Saturn's spectrum, making it easier and more pleasurable to see. The planet will be darkened with shadow from the rings, giving an almost 3-dimensional appearance and an oblong quality when seen through a telescope. If you've got a good enough telescope to see the rings, you'll notice that they'll look flat, but create a more rounded and marble-like quality to the planet itself. You should also be able to distinguish between the A (outside) and B (inside) ring belts on the planet, which are pretty much the coolest thing in the sky. Aside from its famous rings, Saturn is also notable for the presences of its many moons, which are often visible in the foreground of the planet if the viewing conditions are right and you've got a powerful enough telescope. There's even an app for that.
summary: Locate the constellation Look for a golden color shining steadily. Use a telescope. Look for the dark edges. Check out the rings. Check out the moons.
