– What is a 12 Lead ECG?

Recording Your Heart's Electrical Signals

An electrocardiogram (ECG) measures the electrical activity of your heart. A standard 12 lead ECG records this activity from twelve different angles simultaneously, giving a comprehensive picture of how your heart is functioning in that moment.

Small adhesive electrodes are placed on your chest, arms and legs. These are connected to a machine that records your heart’s electrical impulses over approximately 10 seconds. The whole procedure is completely painless and takes around 15 minutes from start to finish, including preparation time.

The resulting trace is reviewed and reported by one of our consultant cardiologists, and a written report is typically available on the same day.

Your Appointment

What to Expect

Arrive & Check In

No special preparation is needed. Simply arrive at your appointment time. Our reception team will check you in and take your relevant details.

Electrode Placement

You will be asked to undress to the waist. A clinician will clean the skin and attach small adhesive electrode pads to your chest, arms and ankles.

The Recording

You will lie still for around 10 seconds while the machine records your heart's electrical activity. The procedure is entirely painless.

Receive Your Results

A consultant cardiologist reviews the trace and produces a written report. This is typically available the same day and sent to you and your GP.
No specific preparation is needed. You can eat, drink and take your regular medications as normal before your appointment. It can be helpful to wear loose clothing that allows easy access to your chest and forearms.
A 12 lead ECG is very effective at detecting certain conditions — including arrhythmias, heart block, signs of a previous heart attack, and structural changes. However, because it only records for around 10 seconds, it may not capture intermittent problems that don't happen to occur during the recording. If your symptoms are infrequent, a 24-hour or longer Holter monitor may be more appropriate.
In most cases, yes. Your ECG trace is reviewed immediately and a verbal summary can be given at the time of your appointment. A formal written report from the reporting cardiologist is typically sent to you and your GP the same day or the next working day.
No — they are different tests. An ECG measures the electrical activity of the heart and is used to assess rhythm and detect certain structural problems. An echocardiogram is an ultrasound of the heart and provides detailed images of its structure, valves and pumping function. Both tests are often complementary and may be recommended together.
