Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

A holter monitor is a small,
portable ECG recorder that's worn for either 24, 48 or 72 hours. It records the heart rhythm during normal daily activities and while sleeping. This may identify slow, fast or irregular heart rhythms that may be responsible for symptoms such as fainting (syncope) or palpitations (feeling a fast or irregular heart beat). Nuclear Cardiology has 24 or 48 hour monitors.
