ECG Test: What You Need to Know

An ECG, or electrocardiogram, is a common test used to check the electrical activity of the heart. It is a simple, quick, and painless test that can help doctors understand how the heart is beating.

If you have been advised to get an ECG, understanding what the test involves can make the process easier.

What Is an ECG Test?

An ECG records the electrical signals produced by your heart. Small electrodes are placed on different parts of the body, including the chest, arms, and legs.

The electrodes detect the heart's electrical activity, which is then shown as a waveform on an ECG machine. A doctor or trained medical professional can study the results to look for irregularities in the heart's rhythm or electrical activity.

Why Is an ECG Done?

An ECG may be recommended for different reasons. Some common symptoms that may lead to an ECG include:

• Chest discomfort or pain

• Irregular or fast heartbeat

• Dizziness

• Fainting

• Shortness of breath

• Unusual tiredness

Doctors may also recommend an ECG during routine health checkups or when monitoring an existing heart condition.

How Is an ECG Performed?

An ECG usually takes only a few minutes.

You will normally be asked to lie down while small electrodes are attached to your skin. The electrodes are connected to the ECG machine, which records the electrical signals from your heart.

The test itself does not send electricity into your body and is generally painless.

Is Preparation Needed Before an ECG?

A standard ECG usually does not require special preparation. However, it is useful to wear comfortable clothing and avoid applying creams or oily products to the areas where electrodes will be placed.

If your doctor or diagnostic centre provides specific instructions, follow those instructions before the test.

What Can an ECG Detect?

An ECG can provide information about the heart's rhythm and electrical activity. It may help doctors identify certain abnormalities, including irregular heart rhythms and some signs of heart-related problems.

However, an ECG is only one part of a medical evaluation. Your doctor may recommend additional tests depending on your symptoms and medical history.
