Ischemia is not a familiar term to many. This article is an attempt to explain it and to clarify it. Ischemia is a form of coronary heart disease that occurs when fat deposits and plaque serve to narrow the interior of an artery to such a severe point that the heart is not able to receive enough oxygen-rich blood for its purposes and is therefore deprived. In as simple terms as possible, ischemia is a restriction in blood supply. What ends up happening is the heart muscle cramps. In this way then, ischemia that takes place in the heart is very much like getting a severe cramp in your leg, only cramping of the heart is more serious than cramping that occurs in the leg area. Ischemia usually takes place when the heart is in need of an extra supply of oxygen. This is most likely to take place when there is a great deal of physical activity or exertion such as during weight training or practically any form of exercise, when a person is eating, when an individual is either very excited or under a great deal of stress and when a person is exposed to extreme temperatures, such as the very cold. Coronary artery disease can become so severe that ischemia can begin to take place even when a person is in a resting state. Sometimes ischemia can be relieved quickly and easily and other times, or for some individuals it takes much longer. When it can be dealt with and gotten out of the way in a reasonably speedy span of time, such as within a 10 minute period with the help of either bed rest or medicine then it is sometimes given the name "stable coronary heart disease" or in other cases simply called, "stable angina." When blood vessels are blocked or become constricted due to ischemia what takes place is angina pectoris. This condition can occur for a number of reasons. It can take place as a result of tachycardia, which is an abnormally fast heartbeat, or due to thromboembolism, which are blood clots. Angina pectoris can also take place due to atherosclerosis, which is defined as "lipid-laden plaques obstructing the lumen of arteries", and hypotension, which is the technical name for low blood pressure, which is likely to occur in cases of heart failure or septic shock. But there are still other reasons why angina pectoris in relation to ischemia could take place. A tumor could cause outside compression or pressure on a blood vessel, which could bring about the problem. There could be foreign bodies in existence that could cause the problem, such as in the case of a pregnant woman, amniotic fluid that is in evidence within an amniotic fluid embolism. Finally angina pectoris could also occur as a result of sickle cell disease, which constitutes hemoglobin that is shaped abnormally. Due to the fact that oxygen is connected to hemoglobin in all red blood cells, when there is an inadequate flow of blood the tissue then becomes hypoxic and in extreme cases, with no oxygen supply whatsoever, it becomes anoxic. A state of anoxic can lead to the death of cells, which is known as necrosis. When necrosis occurs as a result of ischemic it generally takes anywhere from 10 to 12 hours to occur.

This article describes in some detail what an electrocardiogram is, how it works and how you are impacted. An electrocardiogram, which is sometimes referred to simply as an ECG or an EKG, is a diagnostic tool that doctors and medical professionals use to measure a patients heart activity by paying attention to the electric current flowing in the heart. This is a procedure that is fairly routine and is performed all of the time. It generally takes five to ten minutes to do and it is both simple and safe to perform. For the most part, it is standard for a resting ECG to be administered to patients. A resting ECG takes place when the patient is lying on his or her back and the doctor or technician places metal sensors at the persons wrists, ankles and a number of places in the chest area. The sensors are able to detect the electric impulses of the heart, which are then recorded as special tracings on strips of graph paper. An ECG is not uncomfortable as the current is always coming only from the patient and from nowhere else. In a general sense a normally beating heart brings about the same pattern of waves in everyone. If this pattern varies at all, it is potentially due to a multitude of problems which could include irregular heart rhythms, which could be a sign of heart disease but is not necessarily so; damage to the muscle of the heart; enlargement of the chambers of the heart; an imbalance of minerals in the blood and finally, whether or not a patient is having or has already had, a heart attack. Most people who show signs of heart disease will find an ECG useful in helping to isolate the problem. It is important to note that an electrocardiogram is not foolproof. It is possible to have an ECG that is normal but still be afflicted by heart problems. The opposite can also be true - sometimes the graph from the ECG can show problems where there are none at all. Atherosclerosis, which is the buildup of fat in artery walls that causes blocked or narrowed coronary arteries, is not always revealed with a resting ECG due to the fact that when the heart is at rest, it is receiving enough oxygen. In this instance, a doctor may decide that a stress ECG that looks at the condition of the blood vessels of the heart is in order. A stress ECG is done while a patient is either riding a stationary bike or exercising on a treadmill. A stress test or stress ECG can show signs that there is an inadequate supply of oxygen to specific spots of the heart muscle. The most common case of this problem is narrowing of coronary arteries, which are clogged due to the buildup of plaque. The stress test can uncover problems that would be undetected until a person finds himself or herself suffering from a pain in their chest while they are engaging in physical activity. Electrocardiograms are most often a routine part of a physical checkup after a person turns forty years old. It is highly recommended that a person have an ECG before they turn forty so later on it can be used for comparison purposes.

This article is about mechanisms to assist you in achieving blood pressure lower. These are largely available to all of us. The heart is a muscle that is approximately the size of a fist. The heart is one of the busiest and most strenuously worked of all of the organs in the human body. It is estimated that over the span of an average persons life, the heart beats approximately two and a half billion times without requiring the need for a rest How healthy our heart remains throughout our lifetime has a lot to do with the type of lifestyle we subscribe to. In order to keep blood pressure lower, but not too low, it is important to make heart-healthy choices on a day-to-day basis. According to research done by the American Heart Association (http://www.americanheart.org), the number one killer disease in the United States is cardiovascular disease. This deadly disease claims more than 2,600 individuals on a daily basis which works out to be one heart related fatality every 33 seconds in this country. Although these are staggering statistics, there are ways to have blood pressure lower that can help encourage a healthy and long life Blood pressure lower can be obtained by eating a diet that is low in salt and saturated fat and by getting plenty of exercise on a regular basis. Other ways to experience blood pressure lower and encourage a healthy heart involve not overburdening the workload on your heart by cutting out bad habits such as smoking and drinking. The University of Maryland Medical Center has some solid suggestions for how you can get blood pressure lower and keep it that way. Lets take a look at two of the heart healthy, blood pressure lower suggestions- that of including exercise in your day-to-day life as well as eating a healthy diet. Blood pressure lower is more likely if you get plenty of exercise on a regular basis as those with a "coach potato" type of lifestyle are more likely to have elevated levels of blood pressure and are also more prone to obesity. Obesity can also adversely affect blood pressure levels. Exercise helps to make blood flow more freely through the vessels, which in turn encourages a substance known as nitric oxide to be released. Nitric oxide fights the buildup of plaque in the arteries and helps to keep them strong Be aware that finding time to exercise daily does not mean that you need to run a marathon or spend hours on the treadmill. Aim for approximately thirty minutes of exercise per day and vary the activities you do to discourage boredom. Avoid foods that are high in saturated fat, cholesterol and salt. Choose lean meats, fish, and whole grains, plenty of fruits and vegetables and low fat milk. Broiling meats is preferable to frying them and not eating the skin off of meats is a good way to keep your arteries clear of plaque. Keep in mind that fruits and vegetables are choked full of vitamins, minerals and antioxidants that help to keep your circulatory system strong.

The purpose of this article is to provide information about a blood pressure monitor and how to use it. This is especially important if you are going to be monitoring your own blood pressure in a home environment. A blood pressure monitor is a device that measures blood pressure, or hypertension. When you go to the doctor to have your hypertension check, the doctor places a rubber cuff around your arm and tightens it in order to cut off blood flow for a very short span of time. The blood pressure monitor is used to pump up the cuff and then it is used to get an accurate reading of your level of hypertension. The device most commonly used by medical professionals is known as a sphygmomanometer. For those suffering from hypertension, a doctor may recommend that the patient obtain an instrument so they can perform their own readings on a regular basis. There are both automatic (also referred to as digital or electronic) and manual monitors. One of the most convenient types of monitors to use at home is one that is gaining in popularity, which is the digital electronic sphygmomanometer. This is composed of an arm cuff as well as an electric monitor, which allows you to see what your actual reading is. There are also monitors that can be worn on the wrist however these kinds tend not to give as accurate a reading as the aforementioned one. Blood pressure monitors allow for self-measurement, which makes it possible for an individual to be more involved in their own care. This gives many patients confidence as well as a greater sense of control over their circumstances. They are also excellent devices for people who note that their blood pressure seems to only be high when they are visiting their doctor. Blood pressure can shoot up as a result of nervousness and stress therefore a home monitor will allow you to get a more accurate reading when you are in your own everyday environment. Blood pressure units that are geared towards monitoring at home are broken down into three categories- mercury sphygmomanometer, aneroid equipment and automatic equipment. Adults or children who have arms which are larger or smaller than average size might need to buy a special-sized rubber cuff that can be purchased either at select pharmacies or through a medical supply company (orders might be taken by way of a website as well). When it comes to choosing an appropriate instrument, it is important to discuss the options with your doctor to determine what is most suitable for you and your lifestyle. Always choose a unit that meets the necessary validation requirements according to the medical community. Your physician should be able to supply you with this information. Carefully read all instructions before you try out the monitor and make sure that the unit you bought is every bit as precise as the readings obtained in the doctors office. Have your doctor explain to you how to use your personal blood pressure monitor but keep in mind that you still need to make regular visits to see a healthcare provider. Home blood pressure units are not a substitute for expert medical care.
