What is an ECG?
A simple, quick and completely painless procedure
An ECG (Electrocardiogram) is used to record the heart’s rhythm and electrical activity. The purpose of an ECG is to find out if the heart is healthy by detecting irregular heart rhythms and to help diagnose the cause of symptoms such as chest pain or palpitations.
The heart’s electrical activity is measured through electrodes which are attached to the skin with adhesive pads. These electrodes measure the electrical signals of the heart. The signals are displayed on a screen and can be traced out on a piece of paper.
An ECG can identify problems with your heart including:
- A heart attack
- An enlarged heart that is working under strain
- Fast, slow or irregular heartbeats, know as 'arrhythmias'
An ECG can also help investigate the cause of chest pains, palpitations, or symptoms such as difficulty in breathing.
