Welcome to the ECG Library at St. Emlyn’s. Please use the following links to see example ECGs on common problems in emergency medicine and critical care. We are indebted to Dr Michael Colquhoun, a retired doctor from the South West of England who collated and described a range of typical ECGs that cover the major pathologies that we see. He has very kindly agreed to allow us to publish these on the St Emlyn’s website in order to provide a learning library for current and future generations of clinicians. As some time has passed from the original edition we have changed some of the stories and investigations to reflect modern practice. We will add to his original collection as cases and time allow.
Dr Michael Colquhoun has now left clinical practice behind, and now runs his own website specialising in wildlife and bird photography. You can check his website here.
