Electrocardiogram (ECG or EKG)

If you’re experiencing chest pain, palpitations, or dizziness, your doctor may order an electrocardiogram. An electrocardiogram (also called an ECG or EKG) is a quick, noninvasive test that can help identify a wide range of heart conditions. Conditions may include heart arrythmia (irregular heartbeats) and coronary artery disease (narrowed or blocked heart arteries that reduce blood flow). 

At Westchester Medical Center Health Network (WMCHealth), we offer ECG testing as a standard part of cardiac evaluation. We use the latest tools and technology to make sure your results are fast, clear, and reliable. This gives us a clearer picture of how your heart is working, so we can help you choose a treatment plan that fits you best. 

What to Know About Your ECG 

Knowing what to expect before, during, and after your ECG can help you prepare for a smooth appointment. 

How to Prepare for an ECG 

• Wear a loose-fitting, two-piece outfit, if possible. This will help your echocardiographer, who will perform the test, easily place electrodes on the needed areas of your body. 
• Don’t use lotion or oil on your skin the day of the test. They can make it harder for the electrodes to stay on. 

What to Expect During the ECG  

This test doesn’t hurt and usually takes less than 10 minutes. Your echocardiographer will: 

• Place small electrodes (sticky patches) on your chest, arms, and legs.  
• These patches connect to a machine that records how your heart is working. 
• You’ll lie still and breathe normally while the machine records. 

What to Expect Afterwards 

After your ECG, you can go back to your normal activities right away. A heart doctor will check your results and let you know if you need any follow-up care.
