Tachycardia refers to an abnormally fast resting heart rate - usually at least 100 beats per minute. The threshold of a normal heart rate (pulse) is generally based on the person's age. Tachycardia can be dangerous; depending on how hard the heart has to work.
In general, the adult resting heart beats between 60 and 100 times per minute (some doctors place the healthy limit at 90, so some of them may diagnose tachycardia at slightly lower than 100 beats per second). When an individual has tachycardia the upper or lower chambers of the heart beat significantly faster - sometimes this happens to both chambers.
When the heart beats too rapidly, it pumps less efficiently and blood flow to the rest of the body, including the heart itself is reduced. The higher-than-normal heartbeat means there is an increase in demand for oxygen by the myocardium (heart muscle) - if this persists it can lead to myocardial infarction (heart attack), caused by the dying off of oxygen-starved myocardial cells.
Some patients with tachycardia may have no symptoms or complications. Tachycardia significantly increases the risk of stroke, sudden cardiac arrest or death.
Our heart rates are controlled by electrical signals which are sent across heart tissues. When the heart produces rapid electrical signals tachycardia occurs.

Everyone wants to be healthy, and that's a fact. Now in these days of glorious burgers and fries,
how can you maintain being fit and healthy? The answer still is the same since time immemorial. Good food, exercise, and a healthy lifestyle. Yeah still these stuff are the three kings, but how do you define good health food anyway? Here are a few tips that will help ya.
•All natural food is healthy. Taken in moderation, non-processed foods are good for your body. But don't take the misconception that processed foods are bad. Because they aren't bad either, when taken in moderation that is. So the secret lies in control of food intake, as whether your food is bad or good depends primarily on how you control it.

•The food you should take is in complimentary to your level and kind of activity. Did you know that your brain only accepts sugars, primarily glucose as it's source of energy? Contrary to the heart and muscle cells, which can utilize fatty acids as its energy source, your brain is very picky to what it takes. Hence if your work is all about thinking and using your brain, you should eat more carb and less fatty foods. As you won't be able to utilize fats and they'll likely get stored in your body. On the other hand, if your work is all about muscles, then you're welcome to have a higher portion of fats in your diet.

•Not all fats are equal. Just like how not all people are equal, there are also differences with the kinds of fats. The two primary groups of fats are named the 'saturated' (chemically speaking, they're those that doesn't have double bonds in their structure) and the 'unsaturated' (those with double bonds in their chemical structure).
When going for fatty foods, you might want to look for unsaturated fats because these are the ones healthier. Saturated fats account for most of the deadly diseases as these fats tend to clump up and stick together thus blocking blood vessel pathways.
Basically, fats that come from animal sources have high ration of saturated-to-unsaturated hence they should be taken in moderation. Beef fat has the highest while fish fats have more unsaturated fats. Those coming from plant sources tend to be in the middle in terms of this ratio.
