Interpreting an EKG -

by: Damian Sofsian

EKGs can assist doctors in diagnosing and determining any current or past heart abnormalities and are often a regular screening for those with heart disease. Through electrodes attached at various strategic body points, the EKG machine records the electrical impulses of the heart. The results of the impulses are displayed on a computer monitor and then printed onto graph paper. The attending physician or EKG technician interprets your heart health by reading the graphed EKG image.

EKGs are a critical tool for medical professionals to diagnose and treat heart ailments. The EKG reading of your heart is compared to the reading of a standard/normal heart in order to get an idea of your heart function. Abnormalities in the heart rate, heart rhythm or contractions and relaxations can signal the presence of past heart attacks, heart disease or coronary artery disease. If any of these symptoms are present, your doctor will refer you for further testing.

There are literally dozens of different methods for interpreting EKGs but most begin with a search for recurring patterns. One of the first things EKG technicians look for is heart rate. Electrodes are used to stimulate the heart into contracting and then relaxing. The first spike in the reading (the �P� spike) represents the impulses from the upper chamber of the heart. A flatter line called the �PR� interval represents a bridge between the contracting and relaxing of the atria. Each EKG has various other spikes and dips representing heart electrical waves; each spike or dip is referred to by an alphabetic letter.

Most normal hearts have a pattern with a slightly varying rhythm. This is called sinus arrhythmia and is considered normal and healthy. The absence of sinus arrhythmia may indicate other problems with the heart. In EKG interpretation, the lack of sinus arrhythmia has been seen to predict the occurrence of sudden death from heart attack or heart failure. The results of an EKG may become the basis for additional treatment. Your doctor will decide if further evaluation is needed. EKG technicians are highly trained and skilled medical professionals; many physicians consider these technicians to be the first authority in interpreting the EKG results.

Please Note: Professional EKG readings require a great amount of training and education. Since many methods exist to interpret these readings, it is often difficult for non-medical people to understand the terminology. If you are having an EKG performed, your technician will be glad to answer any questions regarding the EKG reading. If you notice something that seems abnormal to you, the technician may be able to calm your fears and by explaining the results in layman's terms.

Prevent Heart Disease
by: Mike Spencer

You should always keep in mind that whatever actions you do today can either help to prevent, delay or minimize the effect of heart disease or worsen it. The key is to control risk factors. Granted that you cannot control every risk factor for heart disease such as family history but you can definitely do something about your behavior. Age and gender also influence your risk of heart disease.

Major Risk Factors of Heart Disease

Cholesterol Levels

Cholesterol is a type of a lipid, a soft, fatlike substance that serves as a source of fuel. Excessive cholesterol can cause buildup of atherosclerotic plaque. Accumulation of plaque in arteries can block blood flow and lead to a heart attack. LDL cholesterol, the so-called "bad" cholesterol, is transported to sites throughout the body, where it's used to repair cell membranes or to make hormones. LDL cholesterol can accumulate in the walls of your arteries. HDL cholesterol, the so-called "good" cholesterol, transports cholesterol to the liver, where it's altered and removed from the body.

Blood Pressure

Normal blood pressure level is defined as less than 130 millimeters of mercury (mm Hg) for systolic blood pressure and less than 85 mm Hg for diastolic blood pressure. The higher the blood pressure, the more likely it is to take a toll on the heart and on the brain. Blood pressure should be checked whether or not your levels are high. For normal, check once every two years. For high-normal, check once a year. If extremely high, you should get immediate care. Then get multiple measurements to know if a high level is sustained over time.

Diabetes

Another risk factor for heart disease is diabetes, a chronic disease of insulin deficiency or resistance. Type 2 diabetes, the most common type, is associated with obesity and may be prevented by maintaining ideal body weight through exercise and balanced nutrition.

Tips For Controlling Risk of Heart Disease

Stop Smoking

The effect of smoking on your lungs can cause almost every other medical condition.

Get Active

Routine physical activity is highly recommended and helpful in controlling obesity. Try to perform 30 minutes of moderate physical activity every day. Fast walking is one of the best way to prevent heart disease. If you can lose even a small amount of weight, five pounds for example, it may have a positive effect on lipid levels and blood pressure preventing heart disease.

Limit Alcohol Consumption

Limit daily alcohol intake to three ounces or fewer to prevent heart disease. People who drink large amounts of alcohol (six to eight ounces a day) tend to have higher blood pressure.

Watch What You Eat

Eat five helpings of fruits and vegetables daily to prevent heart disease.

Maintain adequate dietary potassium, calcium and magnesium intake.

Reduce saturated fats and cholesterol to stay away from heart disease.
