Electrocardiography (ECG)
An electrocardiogram (ECG) is a test that measures the electrical activity of your heart. It is a painless and non-invasive test that can be used to diagnose a variety of heart conditions, including:
- Heart attack
- Arrhythmias (irregular heartbeats)
- Heart failure
- Coronary artery disease
- Heart muscle disease
You may need an ECG if you have any of the following symptoms:
- Chest pain
- Shortness of breath
- Palpitations (irregular heartbeats)
- Lightheadedness
- Fainting
- Fatigue
You may also need an ECG if you are taking certain medications, such as digoxin or beta-blockers.
Frequently Asked Questions:
What exactly does an ECG measure?
An ECG measures the electrical impulses that make your heart beat, providing a graphical representation of the electrical currents moving through the heart muscle.
How is an ECG performed?
An ECG is performed by a healthcare professional called a cardiologist or electrocardiographer. They will attach electrodes to your chest, arms, and legs. These electrodes will pick up the electrical signals from your heart and send them to a machine that records them.
The ECG recording will show the electrical activity of your heart over a period of time. The cardiologist will then interpret the recording to look for any abnormalities.

What should I expect after an ECG?
You can go about your normal activities after an ECG. There are no special restrictions.
What are the possible findings of an ECG?
The possible findings of an ECG include:
- Normal heart rhythm
- Abnormal heart rhythm
- Signs of heart disease, such as coronary artery disease or heart failure
How long does an ECG test usually take?
The procedure itself usually takes about 5-10 minutes, though you might spend a bit longer at the clinic for preparation and post-test consultation.
Is there any preparation required before undergoing an ECG?
No special preparation is needed. Just wear loose, comfortable clothing and avoid applying lotions or oils before the test.
When and how will I get my results?
Generally, the results are available shortly after the test. Your cardiologist will review the results and discuss any findings with you.
