Adaptive techniques are considered for the estimation of the magnitude-squared coherence spectrum of two simultaneous intracardiac signals. Estimators based on single- and multiple-pass algorithms are proposed. Adaptive estimates of the magnitude-squared coherence spectrum are shown to effectively separate fibrillatory from several nonfibrillatory rhythms on the basis of 5 s of data. The significance of this work for sophisticated antitachyarrhythmia devices is indicated.
