Median frequency and coherence measures of atrial and ventricular fibrillation
Fibrillatory rhythms are poorly characterized by traditional time-domain measures, such as rate. The authors describe two measures not commonly applied in intracardiac signal processing; the median frequency (MF) in the 2 to 9 Hz region of the power spectrum, and the magnitude-squared coherence (MSC) function. These two measures are formally defined. The MF is a robust measure of drug-induced changes in atrial fibrillation, and the MSC is a measure of the degree of organization of atrial and ventricular cardiac rhythms.<>
