The heart is one of the most important organs in your body. Although it is small, it pumps about five quarts of blood, carrying oxygen, to each of your muscles in your body about one thousand times per day. The heart is a muscle controlled by electrical signals produced by the sinoatrial node which is part of the cardiac conduction system. Like all things, malfunctions happen through accidents, defects, and just plain neglect. When things go wrong with the heart, it can very easily become fatal, so it is very important to keep your heart healthy and know your heart rate, along with the factors that go with it.
Your heart rate is the number of times your heart beats per minute; it ranges ...view middle of the document...
“Studies show that if it drops 12 or less beats per minute after one minute, you have a higher risk of death from heart disease. A decrease of 15-25 beats is the normal range and the higher the number, the fitter you are.” (Sinha, 2013).
Your resting heart rate, or RHR, has been shown to be a determinant of risk for death. The higher your RHR is, the more at risk you are for death. “One study showed that a RHR of over 90 beats per minute doubled heart disease death rates in men and tripled heart disease death rates in women.” (Sinha, 2013) Diseases caused by an abnormal heart rate are Tachycardia and Bradycardia.
Tachycardia is an increased heart rate and can be fatal. It sometimes shows no symptoms, but can increase your risk for stroke and heart attacks. Since it is beating much faster than it should, your heart could be depriving your body and organs of the blood that is needed. The symptoms of Tachycardia are caused, in majority, to this lack of blood and oxygen. Some symptoms include: dizziness, fainting, shortness of breath, heart palpitations, and rapid heart rate. Some people are more likely than others to develop this disease; women, those who drink large amounts of coffee, heavy smokers and drinkers, and anxious people are more likely than others to show signs of Tachycardia.
Bradycardia is a disease in which the heart rate is very slow—under 60 beats per minute. Bradycardia is caused by problems in the sinoatrial node, damage to the heart, or metabolic problems (hypothermia). Because the heart is pumping too slowly, the body will not receive enough blood in certain areas which can cause fainting, dizziness, or cardiac arrest. At times, your heart rate can fall below 60 when you are sleeping; that is not a problem. The people diagnosed with this disease usually experience low heart rate throughout the entire day. Also, active people sometimes may have a lower heart rate through conditioning; this, also, is not a problem.
Between 1999 and 2005, the rate of deaths from heart disease decreased 25.8 percent and the rate of deaths by strokes dropped 24.4 percent. This could be possibly due in part to the amount of attention to health and a decrease in smoking. The question is how do those percentages look now? With all the talk about obesity and declining health, you would think that those numbers would decrease dramatically. “An estimated 68 percent of U.S. adults are overweight or obese.”(Hopkins Medicine) “Approximately 20 percent of U.S. adults smoke cigarettes, costing $193 billion per year.” (Hopkins Medicine) With these statistics, it’s easy to believe that about 84 million suffer from a type of heart disease today which makes it the number one leading cause of death in the United States.
“In a 2005 survey, most respondents—92%—recognized chest pain as a symptom of a heart attack. Only 27% were aware of all major symptoms and knew to call 9-1-1 when someone was having a heart attack.” (CDC) Knowing your body is something that...
