About this service
A 12 Lead electrocardiogram (ECG/EKG) records the electrical signals generated by the heart from several viewpoints. It is commonly used to support clinical assessment of heart rate and rhythm and to look for electrical patterns that may need further evaluation.
What to expect
Small adhesive electrodes are placed on the skin, usually on the chest, arms and legs, and connected to an ECG machine. The tracing is recorded while you remain still. The process is generally brief, though preparation and interpretation take additional time.
How to prepare
Follow the instructions from your healthcare professional or the appointment team.
- Wear clothing that allows access to the chest, wrists and ankles.
- Let the clinician know about any medicines or relevant medical information they ask about.
- Try to stay still and relaxed while the tracing is recorded.
Understanding results
An ECG tracing is not a complete assessment of every heart condition. A qualified healthcare professional should interpret the recording alongside symptoms, history and any other required investigations.
