University of Glasgow Interpretive Algorithm.

World Leading Software for ECG Analysis

An ECG is considered the single most important initial clinical test in the evaluation of an acute coronary syndrome, which includes what is commonly known as a heart attack. Correct interpretation of the ECG, particularly in an ambulance or emergency department, is usually the basis for immediate therapeutic interventions and/or subsequent diagnostic tests.

Developed by Professor Peter Macfarlane and his team in the Institute of Cardiovascular and Medical Sciences (Glasgow Royal Infirmary), the University of Glasgow ECG Analysis Program has been adopted commercially and applied world-wide. It is now used globally by some of the world’s leading electro-medical device manufacturers and has been continually improved since its initial development, allowing it to stay abreast of the latest advancements in electrocardiographic research. Such research in Glasgow has also significantly influenced international guidelines for diagnosing a heart attack from the ECG.

The software is a massive export success with an estimated 20 million patients a year worldwide coming into contact with the technology on the basis of units sold. In 2007, after dealing across the globe, the University struck its first Scottish license deal with a small-to-medium-sized-enterprise, Inverness-based Dan Medical.

The ECG software was first licensed to Siemens Elema, based in Sweden, in 1981 when commercialization of University work was rare. The University’s first Industrial Liaison Office had not even been formed then!! This link with Siemens led to the Glasgow program being incorporated into the Burdick range of ECG machines which are nowadays the most widely used ECG machines in family practitioner offices in North America.

The Glasgow diagnostic criteria have more recently been incorporated into a new patient monitor/defibrillator which was introduced to the world market by Seattle based Medtronic Physio Control in the Spring of 2009. Since its introduction, several hundred units have been sold to Ambulance Services in the United Kingdom alone. The London Ambulance Service (LAS) in particular is now a significant user of the product. The LAS particularly appreciated and understood the reasons for the use of age, gender and race in the Glasgow criteria. This means that for major events in the Greater London area, such as the 2012 Olympic Games, the Glasgow ECG analysis program will be in the forefront of accident and emergency work.
