Electrocardiogram (ECG)

An Electrocardiogram, commonly known as an ECG or EKG, is a commonly used diagnostic test that records the electrical activity of the heart.

During an ECG, small electrodes are placed on specific areas of the body. The electrical signals produced by the heart are recorded and displayed as an ECG tracing.

A physician may recommend an ECG to help evaluate:

• Heart rhythm
• Heart rate
• Certain electrical abnormalities
• Symptoms such as palpitations
• Chest discomfort
• Dizziness or fainting
• Shortness of breath
• Certain cardiac conditions
• Follow-up of known heart problems

An ECG is generally a quick and non-invasive investigation. The results should be interpreted by a qualified healthcare professional together with the patient's symptoms and medical history.
