In 1951, the corporate structure was dissolved and the name changed to General Electric X-Ray Department. This new name lasted less than 10 years as the department divested itself of its industrial X-ray business, widened its medical business, and took on the name of GE Medical Systems Department. One of the reasons for the name of Medical Systems was due to the increase in the electro-medical business, which began in 1961 with the introduction of patient monitoring equipment. By 1967 modular equipment was developed which was soon popular in cardiac and intensive care units. Early in 1960, pacemakers were developed in Corporate Research & Development in Schenectady, New York, and in 1969 the Standby Pacemaker was developed.
