The human heart has always enjoyed a privileged place in conceptions of physical well-being. The University of Iowa Hospitals and Clinics Medical Museum's exhibition, The Beat Goes On: A History of Cardiology, traces the interwoven history of medical knowledge and technological advance from Galen's early description of the circulatory system to modern breakthroughs in prevention, diagnosis and treatment. The exhibition begins with a Time Line, which graphically traces these major developments and identifies heart researchers who have made outstanding contributions.
