Professor Macfarlane is Emeritus Professor and Hon Senior Research Fellow at the University of Glasgow. He was Professor in Medical Cardiology from 1991 – 1995 and Professor of Electrocardiology from 1995 – 2010. His major interest throughout has been the application of computer techniques to ECG interpretation. The work of his team has been adopted commercially and the University of Glasgow ECG interpretation program developed in his laboratory is currently used worldwide. He is particularly interested in differences in ECG appearances due to age, gender and ethnicity, and as a result, he has influenced international guidelines for the ECG definition of acute myocardial infarction. Professor Macfarlane is a Fellow of many learned Societies, including the Royal Society of Edinburgh. In 2000, he was awarded a DSc on the basis of his contribution to research in his own field. In January 2014, he was awarded a CBE for Services to Healthcare.
