Abstract
An approach to a simple, dependable ECG preamplifier designed primarily for use in the operating room is presented. The 60-cps interference is analyzed and a method of reducing this intereference by utilizing the isolation offered by transformer coupling is described. A prototype unit is constructed and tested, and operational characteristics of this unit are presented.
