Howan ECG iscarried out

There are several different ways an ECG can be carried out. Generally, the testinvolves attaching a number of small, stickysensors called electrodes to your arms, legs and chest. These are connected by wires to an ECG recording machine.

You don't need to do anything special to prepare for the test. You can eat and drink as normal beforehand.

Before the electrodesare attached, you'll usually need to remove your upper clothing, and sometimes your chest may need to be shaved or cleaned. Once the electrodes are in place, you may be offered a hospital gown to cover yourself.

The test itself willnormally only last a few minutes, and you can usually go home soon afterwards or return to the ward if you're already staying in hospital.
