An electrocardiogram (ECG) is an electrical recording of the heart and is used in the investigation of heart disease. I am a keen collector of ECGs and I am loading them onto this site. Initially there will be a bias towards the more unusual and informative but, in time, it should become comprehensive. There are many Internet resources of ECGs.
This WWW resource will be a library of ECG recordings, many in full 12-lead format. To display the images on a computer screen some of the clarity is lost but those that are shown have been chosen carefully to prevent any loss of important detail. The size of larger files is shown.
Stephen Gerred (medical registrar Auckland, New Zealand) and I (Specialist Registrar, Llandough Hospital, Cardiff, Wales) have been collecting ECGs for some time and would welcome any comments or additions to our work. Our book 'ECGs by example' published 1997, Churchill Livingstone (ISBN 0 443 056978) contains 80 full size ECGs as they really appear on the wards.
Teaching practical electrocardiography depends on having convincing, authentic looking recordings. If you are interested in restoring some of your fading originals or poor photocopies to their former glory then please email me. We are working on image processing techniques for removing ECG tracings from any type of background.
