Overview

What is Electrocardiography (ECG)?

Electrocardiography (ECG), also known as an Electrocardiogram or EKG, is a simple, non-invasive diagnostic test that records the electrical activity of the heart. By measuring the timing and strength of electrical signals, an ECG provides valuable information about your heart rate, heart rhythm, and overall cardiac function.

At RS Abdi Waluyo, ECG is one of the most commonly performed cardiac tests. It is quick, painless, and plays an essential role in detecting heart conditions, evaluating symptoms, and monitoring heart health.

Why is an ECG Performed?

Your doctor may recommend an ECG to:

Evaluate symptoms such as chest pain, palpitations, dizziness, fainting, or shortness of breath.
Detect abnormal heart rhythms (arrhythmias).
Diagnose signs of a heart attack or previous heart damage.
Assess the heart’s electrical conduction system.
Monitor the effectiveness of medications or cardiac treatments.
Evaluate heart health before surgery or certain medical procedures.
Monitor patients with known heart disease or cardiovascular risk factors.
Investigate unexplained fatigue or reduced exercise tolerance.

An ECG is often the first step in evaluating many heart-related symptoms and conditions.

Details of the Test

An ECG is a safe, painless, and non-invasive examination that typically takes only a few minutes.

During the test:

Small adhesive electrodes are placed on your chest, arms, and legs.
The electrodes are connected to an ECG machine that records your heart’s electrical activity.
No electricity is sent into your body—the electrodes only detect the heart’s natural electrical signals.

In most cases, no special preparation is required. However, you may be advised to:

Wear comfortable clothing that allows easy access to your chest.
Avoid applying lotions, oils, or creams to your skin before the test, as these may interfere with electrode attachment.
Continue taking your medications unless instructed otherwise by your doctor.

What Happens During the Test?

The ECG procedure is quick and straightforward.

During the examination:

You will be asked to lie comfortably on an examination table.
Small adhesive electrodes will be attached to your chest, arms, and legs.
The ECG machine will record your heart’s electrical activity while you remain still and breathe normally.
You may be asked to briefly hold your breath during part of the recording to reduce interference.
Once the recording is complete, the electrodes will be removed.

The entire procedure usually takes 5 to 10 minutes, while the actual recording lasts only a few seconds.

What Should I Expect After the Test?

There is no recovery period after an ECG.

Following the examination:

You may resume your normal daily activities immediately.
There are no restrictions on eating, drinking, or physical activity unless your doctor advises otherwise.
Mild redness at the electrode sites may occur in some individuals but typically resolves quickly.

What Are the Risks?

An ECG is an extremely safe examination with no known medical risks.

Because the electrodes only record electrical activity and do not deliver electricity to your body, the test is painless and non-invasive.

Some patients may experience mild skin irritation from the adhesive electrodes, but this is usually temporary.

Results and Follow-Up

Your ECG will be reviewed by your doctor to assess:

Heart rate
Heart rhythm
Electrical conduction through the heart
Evidence of heart enlargement
Signs of reduced blood flow to the heart (ischemia)
Evidence of a current or previous heart attack
Other abnormalities affecting the heart’s electrical system

Your doctor will explain what the findings mean and determine whether additional evaluation is necessary.

When Will I Receive My Results?

In many cases, the ECG can be reviewed immediately after the examination.

If the ECG is performed as part of a comprehensive cardiac evaluation, the results will be discussed during your consultation or follow-up appointment.

If the Results Are Abnormal, What Are the Next Steps?

If your ECG shows an abnormality, your doctor may recommend additional tests to better understand your heart condition, such as:

Echocardiography
Holter Monitoring (24-hour Ambulatory ECG)
Exercise Stress Testing
Cardiac CT or Cardiac MRI
Blood tests
Cardiac catheterization or coronary angiography, if indicated

Treatment recommendations may include lifestyle modifications, medications, further monitoring, or specialized cardiac procedures depending on your diagnosis.

When Should I Call My Doctor?

Contact your doctor if you experience:

Chest pain or pressure.
Persistent or worsening shortness of breath.
Palpitations that are frequent or accompanied by dizziness.
Fainting or near-fainting episodes.
Unexplained fatigue or weakness.
Any new or worsening symptoms after your evaluation.

Seek emergency medical attention immediately if you experience severe chest pain, sudden shortness of breath, loss of consciousness, or symptoms suggestive of a heart attack or stroke.
