What is an EKG?

An Electrocardiogram (EKG or ECG) is a simple, non-invasive test that measures the electrical activity of your heart. It helps doctors diagnose and monitor various heart conditions by recording the timing and strength of the electrical signals as they pass through your heart.

How Does an EKG Work?

During an EKG, small electrodes are placed on your chest, arms, and legs. These electrodes are connected to an EKG machine that records the electrical activity of your heart. The test produces a graph (EKG tracing) that shows the heart’s rhythm and electrical activity patterns.

When is an EKG Used?

EKGs are used to diagnose and monitor several heart conditions, including:

• Irregular heartbeats (arrhythmias)
• Heart attacks
• Heart disease
• Cardiomyopathy
• Electrolyte imbalances
• Effects of certain medications

Preparing for Your EKG

No special preparation is needed for an EKG. However, it’s helpful to:

• Wear loose, comfortable clothing
• Avoid using lotions or oils on your skin before the test
• Inform your doctor about any medications you’re taking

The EKG Procedure

The EKG procedure is quick and painless. Here’s what you can expect:

1. Electrode Placement: You will lie down, and a technician will place small electrodes on your chest, arms, and legs. These electrodes are attached to the EKG machine with wires.
2. Recording: You will be asked to lie still and breathe normally while the machine records your heart’s electrical activity. The recording typically takes a few minutes.
3. Completion: The electrodes are removed, and you can resume your normal activities immediately.

Understanding Your EKG Results

After the test, your doctor will analyze the EKG tracing. They will look for any irregularities in your heart’s rhythm, structure, or electrical activity. Depending on the results, further tests or treatments may be recommended.

Benefits of EKG

EKGs offer several benefits, including:

• Early detection of heart problems
• Monitoring heart conditions
• Guiding treatment decisions
• Evaluating the effectiveness of certain medications

Possible Risks

EKGs are very safe, with no significant risks involved. Some people may experience slight skin irritation where the electrodes were placed, but this is typically mild and temporary.
