ECG at a Glance

Patrick Davey is Consultant Cardiologist at Northampton General Hospital & Honorary Senior Lecturer at the John Radcliffe Infirmary, Oxford. He was previously a Clinical Tutor at Oxford University.

“This is a refreshing new book in the already crowded field of ECG interpretation books.” (Doody's Reviews, May 2009) Pre-publication reviews: 'Very thorough list of contents, broken down logically into sections....this is a very accessible book that is easy to read from cover to cover.' - Postgraduate Medical Student, Warwick University 'Once again I have been impressed by the level of input and comprehension into each chapter. I have no doubt that my medical students will be carrying around ECG at a Glance as much as they already carry around Medicine at a Glance! Could I be cheeky and ask for a copy or 2 when the book is finally printed! ' - Consultant Cardiologist & Electrophysiologist, James Cook University Hospital, Middlesbrough
