What is the Purpose of an EKG Test?

What is the Purpose of an EKG Test?Often the first test ordered by a physician who is diagnosing a heart problem, an electrocardiogram (EKG) is a simple, convenient examination of the health of the heart that measures its electrical rhythm over a period of time. Painless probes are placed on a patient’s body and connected to screening equipment. The results provide valuable information on the heart rate, timing of beats, and electrical conduction through the heart’s chambers, which can be helpful in evaluating whether the heart muscle has sustained damage. An EKG can identify an arrhythmia, or irregular heartbeat, and also provide evidence of prior heart attacks, which can sometimes go undetected.

Because an electrocardiogram can be key to the early diagnosis and prevention of serious heart problems, this test can be beneficial to anyone who has one or more of the following risk factors:

  • History of smoking
  • Diabetes
  • Hypertension
  • High cholesterol
  • Family history of heart disease or arrhythmias

Of course, if a heart attack is suspected, it’s important to proceed directly to the nearest hospital emergency room. The most common symptoms of heart attack include:

  • Pain, pressure, or other discomfort in the chest
  • Pain or discomfort in one or both arms or the neck, back, jaw, or abdominal area
  • Shortness of breath or breathing difficulties
  • Swelling in the legs
  • Sudden dizziness, nausea, or a cold sweat

Never hesitate to call 9-1-1 in the event of a life-threatening emergency like a heart attack. Emergency medical services (EMS) staff members are trained to begin treatment as soon as they arrive on the scene. Remember: Every minute matters, and fast action can save a life.
