What is it?
A simple, painless procedure to record and detect abnormalities of your heart muscle, rate and rhythm.
How it works
A 12-lead ECG is performed while you lie down. This involves sticking six electrodes onto your chest, and a single electrode on each of arm and leg.
An ECG machine connects all these electrodes via leads. A recording of your heart rate and rhythm is then taken, and analysed to check for any abnormalities. The whole process takes about 10 minutes.
