Patent ID: 8755876

Claim:
A processor implemented method for detecting atrial fibrillation, the processor implemented method comprising: obtaining, using one or more processors executing computer readable code embodied in computer usable media, a time-varying coherence function by multiplying two time-varying transfer functions (TVFTs), the two time-varying transfer functions obtained using two adjacent data segments, each of the two adjacent data segment being related to R-R intervals, with one of the two adjacent data segment as an input signal and another of the two adjacent data segment as an output signal to produce a first TVTF; a second TVTF is produced by reversing the input and the output signals, using said another of the two adjacent data segment as the input signal and said one of the two adjacent data segment as the output signal; and determining, using the one or more processors executing the computer readable code embodied in the computer usable media, whether the time-varying coherence function is less than a predetermined quantity.
