To understand the purpose of performing a 12-lead electrocardiogram (ECG)
To familiarise yourself with the preparation and equipment required when undertaking a 12-lead ECG
To enhance your knowledge of the correct positioning of the chest and limb electrodes
A 12-lead electrocardiogram (ECG) is a painless procedure commonly undertaken in healthcare practice. An ECG machine uses cables or ‘leads’ attached with stick-on electrodes to specific parts of the body to create a series of ECG traces, which are then printed onto graph paper. This provides a recording of the cardiac electrical activity measured from different angles or perspectives.
• A 12-lead ECG is a valuable diagnostic tool that has proven effective in detecting various cardiac abnormalities or enabling healthcare professionals to rule them out.
• It is a cost-effective investigation that can be performed by any appropriately trained healthcare professional.
• Careful preparation and correct electrode and lead placement are crucial to ensure accuracy when recording a 12-lead ECG.
