What is Electrocardiography?

Electrocardiography, commonly known as ECG or EKG, is a non-invasive test that records the electrical activity of your heart over a period of time. It’s used to detect and monitor various heart conditions by measuring the heart’s rhythm, electrical impulses, and muscle activity.

What happens during Electrocardiography?

During the test, small adhesive electrodes will be placed on your chest, arms, and legs. These electrodes are connected to an ECG machine that records your heart’s electrical activity. You will need to remain still and breathe normally during the test, which typically lasts just a few minutes. The results are recorded as a series of waves on a graph, which your doctor will analyze to assess your heart's condition.

Why would I need Electrocardiography?

You might need an ECG or EKG to:
 

• Evaluate symptoms such as chest pain, dizziness, shortness of breath, or palpitations.

• Detect abnormal heart rhythms (arrhythmias) or heart conditions like heart attacks.

• Monitor the effects of medications or other treatments for heart disease.

• Assess the health of your heart if you have a history of heart disease or are at risk.

• Provide a baseline before surgeries or other medical procedures.

Who needs Electrocardiography?

Electrocardiography may be recommended if you:
 

• Experience symptoms like chest pain, palpitations, or unexplained dizziness.

• Have a history of heart disease or are at risk due to factors like high blood pressure,
  diabetes, or a family history of heart conditions.

• Are taking medications that can affect your heart’s rhythm or function.

• Are undergoing evaluation before surgery or other procedures.

• Require monitoring of your heart’s condition over time.

What are the risks of Electrocardiography?

Electrocardiography is a very safe and non-invasive procedure with no significant risks. The only potential issue might be minor skin irritation where the electrodes are applied. There is no risk of electric shock or other complications from the test itself.

How do I prepare for Electrocardiography?

To prepare for the test:
 

• Wear loose, comfortable clothing that can easily be removed or adjusted to expose your chest, arms, and legs.

• Avoid using lotions, oils, or powders on your skin before the test, as these can interfere with electrode placement.

• Inform your healthcare provider about any medications you are taking, as they may affect the results.

• Relax and remain as calm as possible during the test to ensure accurate readings.
