ABSTRACT:
Physiological electrical signals such as electrocardiograph signals ae converted to digital form, amplified to a standard maximum amplitude and analyzed by a computer. The analysis may calculate the ratios of energies above and below an isoelectric line, the statistical distribution of gradients, the frequency of a maximum negative gradient and the zero content of the signal. The analysis may be used for detecting ventricular fibrillation.
