Chicago’s first electrocardiograph was installed 100 years ago at Presbyterian Hospital, which later became part of Rush University Medical Center.
Renowned heart specialist and Rush Medical College graduate James B. Herrick, MD, was instrumental in securing the equipment through a gift from Mrs. Cyrus McCormick, Sr., a noted Chicago philanthropist.
She also helped the hospital acquire an improved model in 1915 and provided substantial funding for research in heart disease.
According to the 1939 issue of the Presbyterian Hospital Bulletin, “It was with the aid of these instruments that Dr. Herrick made his first notable discoveries about coronary thrombosis and started on the trail which has brought fame to himself and immeasurable benefit to humanity.”
Electrocardiography measures the heart’s electrical activity and helps detect abnormalities.
