Focus on Healthy Senior Citizens
Researchers studied 2,192 healthy adults aged 70 and older for eight years in Memphis, Tenn., and Pittsburgh. Those with EKG abnormalities had more heart attacks. The results were consistent even when researchers took into account known risk factors for heart attacks, such as smoking, high cholesterol, high blood pressure and diabetes.
Gender and Racial Variations?
Researchers were also interested in whether or not gender or self-reported racial differences played a role in determining a healthy person’s likelihood of a future heart attack among the 2,192 participants who identified themselves as either Caucasian or African American.
Controversy Surrounding EKGS
Organizations such as the American Academy of Family Physicians recommends against ordering annual EKGs or any other cardiac screening for low-risk patients without symptoms. They say “there is little evidence that detection of coronary artery stenosis in asymptomatic patients at low risk for coronary heart disease improves health outcomes.”
Why is an EKG important?
It is an important tool for diagnosing conditions affecting the heart. Most people will undergo an EKG at some point. Although having an abnormal EKG can seem scary, it is important to understand that it is just one part of a proper diagnosis. Many things can cause an abnormal EKG, and not all of them are dangerous.
Why do people get EKGs?
Many people will get an EKG reading at some point in their lives, often due to experiencing common symptoms such as chronic chest pain, shortness of breath, or a rapid pulse.
What does an EKG show?
Irregular heart rate. An EKG will pick up any irregularities in a person’s heart rate. The human heart typically beats at around 60–100 beats per minute. A heart that beats any faster or slower than this may indicate an underlying issue. A doctor will want to run additional tests to find the underlying cause.
How long does an EKG monitor work?
Since this is unlikely, doctors may recommend using a Holter monitor, which monitors the heart’s activity for 24 hours or longer .
What does it mean when your EKG is abnormal?
Heart attack. Sometimes, an abnormal EKG result may be a sign of a serious issue, such as a heart attack . When a person has a heart attack, the heart can lose its fresh supply of blood, which can cause tissue damage and even cell death.

Overview
Why It's Done
- An electrocardiogram is a painless, noninvasive way to help diagnose many common heart problems. A health care provider might use an electrocardiogram to determine or detect: 1. Irregular heart rhythms (arrhythmias) 2. If blocked or narrowed arteries in the heart (coronary artery disease) are causing chest pain or a heart attack 3. Whether you have...
Risks
- An electrocardiogram is a safe procedure. There is no risk of electrical shock during the test because the electrodes used do not produce electricity. The electrodes only record the electrical activity of the heart. You may have minor discomfort, similar to removing a bandage, when the electrodes are removed. Some people develop a slight rash where the patches were placed.
How You Prepare
- No special preparations are necessary for a standard electrocardiogram. Tell your health care provider about any medications and supplements you take. These can often affect the results of an ECG.
Results
- Your health care provider might discuss results with you the same day as your electrocardiogram or at your next appointment. ECGresults can give a health care provider details about the following: 1. Heart rate. Usually, heart rate can be measured by checking the pulse. An ECG may be helpful if your pulse is difficult to feel or too fast or too irregular to count accurately. An ECGc…
