What Is an Electrocardiogram

An electrocardiogram (EKG) is a quick test that your cardiologist uses to assess your heart function. Your Tomball, TX, cardiologist, Dr. Daljit Muttiana of Cardiovascular Institute, uses EKGs and other diagnostic tests to determine if you have a problem with your heart.
When are EKGs recommended?
Your Tomball heart doctor may order an EKG if:
- You have chest pain, fatigue, dizziness, shortness of breath, palpitations, or an irregular heartbeat.
- Your legs, ankles, feet or abdomen are swollen.
- You have an increased risk of developing heart disease, due to smoking, high blood pressure, high cholesterol, diabetes, or a family history of the disease.
- He wants to see how well you're responding to a particular heart treatment.
- You have high blood pressure, diabetes, or another chronic condition and want to try a new form of exercise.
What information does an EKG provide?
An EKG provides information on heart rate, rhythm, and electrical activity in the heart. It can also be used to determine if you've had a heart attack, your heart is enlarged or if your heart is receiving sufficient oxygen.
How are EKGs performed?
Before your EKG begins, a technician will attach adhesive electrodes to your chest, arms, and legs. The electrodes are connected to wires that transmit heart readings to a monitor.
During the test, you'll lie down and remain perfectly still. Fortunately, the test only takes a few minutes and is completely painless. In fact, removing the sticky electrodes at the end of the EKG may be the only slightly uncomfortable part of the test.
In some cases, EKGs may be used to monitor how your heart responds to physical activity. In this case, you won't need to remain still but will run on a treadmill or ride an exercise bike.
When will my cardiologist give me the results of my EKG?
Your cardiologist may discuss your results with you as soon as the test is finished. If any abnormalities are detected, he may recommend a few more tests. Additional testing may still be needed if you have symptoms but your EKG is normal, as the test only detects certain kinds of abnormalities.
