The bispectrum and bicoherence spectrum have been shown to be powerful techniques for identifying different types of nonlinear system responses. This paper presents an introduction to bispectral techniques applied to biomedical signals and examines the bispectral properties of the human electrocardiograph (ECG). The bispectrum proves to be an effective tool for representing and distinguishing different ECG response types. Bispectral ECG analysis is non-invasive and may prove to be a useful discriminant diagnostic.
