Twelve-lead simulation for testing interpretive ECG machines

Abstract

A 12-led electrocardiogram (ECG) simulator for producing realistic signals that are useful for testing interpretive ECG machines has been developed. The simulator synthesizes about 100 12-lead ECGs with different morphological characteristics and rhythms. The operator can control the heart rate and the amplitudes of a sinusoidal baseline drift function, a pseudorandom noise source, and 60-Hz interference. The simulator, written in the C programming language on an IBM PC, provides the ECG signals through a multichannel digital-to-analog converter.<>
