Other Names: EKG, ECG, resting ecg or ekg

Description/Test Basics/Reasons for the test: An electrocardiogram is a painless non-invasive test that measures and records the electrical impulses, or activity, of the heart.  Each heart beat is triggered by an electrical impulse generated from within your heart. An electrocardiogram records these electrical signals as they travel through your heart. 

An electrocardiogram can be used to:

  • Find the cause of unexplained chest pain
  • Find out if the walls of the heart chambers are too thick (hypertrophied).
  • Find the cause of symptoms of heart disease, such as shortness of breath, dizziness, or rapid, irregular heartbeats (palpitations, arrhythmia's).
  • Check a patient's response to therapy; check how well medicines are working and whether they are causing side effects that affect the heart.
  • Check how well mechanical devices such as pacemakers are working to control a patient's heartbeat.
  • Check the health of the heart when other diseases or conditions are present, such as high blood pressure, high cholesterol, cigarette smoking, diabetes, or a family history of early heart disease.

Test preparation/pre-test guidelines: Patients should not strenuously exercise right before the test. 

Test process/How the test is done: The patient lies down and approximately 10 electrodes are attached to your chest. The electrodes record the heart's electrical impulses and transmit them to an electrocardiograph.

Post-test guidelines: Most patients can resume normal activity immediately following an EKG test.

Test location: Your EKG test can be performed at all our locations- Denton, Gainesville and Bowie Texas.
