Understanding ECG Scans (12-Lead Electrocardiogram)
An ECG, or electrocardiogram, is a simple and fast test used to check the heart's rhythm and electrical activity. Sensors attached to the skin detect the electrical signals produced by the heart each time it beats. A 12-lead ECG provides information from 12 different angles and is the standard way of recording the electrical activity of the heart.
Purpose and Benefits of an ECG
The primary purpose of an ECG is to assess heart health by measuring the timing and duration of each electrical phase in the heartbeat. It's a crucial part of the assessment of symptoms such as chest pain, shortness of breath, and palpitations. The benefits of an ECG include its non-invasive nature, speed, and accuracy in diagnosing various heart conditions.
Conditions Detected by an ECG
The 12-lead ECG is instrumental in detecting numerous heart-related issues, including:
- Arrhythmias
- Coronary artery disease
- Past heart attacks
- Ongoing heart attacks
- Cardiomyopathy
- Pericarditis
- Electrolyte imbalances
- Other heart conditions

Further Information on the Service
Scan Procedure
An ECG involves attaching a series of electrodes to the skin on the chest, arms, and legs. These electrodes are connected to a machine that records the heart's electrical activity. The 12-lead ECG captures comprehensive data to give a detailed picture of heart health.
Preparation for the Scan
No special preparation is typically needed for an ECG. Patients may be advised to avoid oily or greasy skin creams and to wear clothing that can be easily removed to place the electrodes.
What to Expect on the Day
The procedure is quick, usually taking only a few minutes. Patients lie down while the electrodes are attached. During the ECG, they must remain still, and they may be asked to hold their breath briefly. There is no pain associated with the procedure, although some may find the removal of the electrodes slightly uncomfortable.
After the Scan
There are no special post-scan instructions, and normal activities can be resumed immediately. Results are often available the same day and will be communicated by the healthcare provider who requested the ECG.
Alternative Imaging Options
Depending on the symptoms and the consultant's decision, alternative or additional imaging options like echocardiograms, MRI, or CT scans of the heart may be recommended.
Additional Resources
For further information on ECGs and heart health, patients can visit reputable medical websites or contact heart health organizations for support and guidance.
