What Is an EKG? How Does it Work?
An electrocardiogram or ECG is a test used to diagnose heart problems. Find out what it looks like and how it works!
An electrocardiograph (ECG) is an important diagnostic tool for doctors. It measures electrical activity in the heart by recording the voltage difference between various points on the body. The ECG is often used to detect abnormalities in the rhythm of the heartbeat.
What is an Electrocardiogram (ECG)?
An electrocardiography (ECG) is a simple medical test that records the electrical activity of the heart. This test is commonly performed when there is concern about abnormal rhythms of the heart.
How does an ECG work?
An ECG measures the electrical activity of the muscles of the heart using electrodes attached to the skin. These electrodes record the electrical impulses generated by the heart muscle cells as they contract and relax.
Why should I have one done?
If you have any symptoms of heart trouble, such as chest pain, shortness of breath, dizziness, fainting, or irregular heartbeat, you should see your doctor right away. You might also need an ECG if you have been diagnosed with high blood pressure, diabetes, thyroid disorders, or other medical conditions that affect the heart.
When should I get tested?
It’s important to understand when you should get tested for heart issues. If you have any symptoms, talk to your doctor immediately. If you have had a heart attack or another type of cardiac event, you should get tested within 24 hours.
What happens during the test?
During an ECG, electrodes are attached to your skin to measure electrical activity in your heart. A technician will then use a machine called a stethoscope to listen to your heart rhythm. This helps determine whether there are any abnormalities.
