What is an ECG?
An electrocardiogram or ECG test (not to be confused with an echocardiogram) is a simple test that is used to check the rhythm and electrical activity of your heart. It is often used alongside other cardiac tests to help diagnose or monitor certain heart conditions.
During an ECG, you will have electrodes (small sticky sensors) placed on your chest, arms and legs, which are connected to a recording machine. This machine picks up electrical signals every time your heart beats. The results will then be analysed to see if there is anything unusual with your heart’s rhythm.
