The present paper investigated the use of the coherence spectrum as a method able to discriminate ventricular fibrillation and nonfibrillatory rhythms, when applied to the surface ECG in an animal experiment using rabbits. The magnitude-squared coherence function was calculated using three and five segments averaged and compared with a threshold; if it is greater than the threshold it is a nonfibrillatory rhythm otherwise it is ventricular fibrillation. The sensitivity and specificity obtained in this study encourage the extension of this technique to the analysis of the surface ECGs in humans.
