摘要： An apparatus and a method for detecting cardiac atrial fibrillation events in an EKG signal. The method comprises the steps of detecting a portion of an EKG signal comprising cardiac beats; measuring the duration of a gap in the detected portion of the EKG signal; and computing two or more inter-beat intervals. The computed interval is outputted if the gap in the portion of the EKG signal is not more than a fraction alpha of the computed interval. The method further includes the steps of computing the variance of the inter-beat intervals and classifying the portions of the EKG signal as indicative of an atrial fibrillation event. During classification, the inter-beat interval variance of the portion of the EKG signal that exceeds a pre-determined value V is indicative of an atrial fibrillation event. The method further includes discarding portions of the EKG signal classified as indicative of atrial fibrillation if said portions have a duration less than a pre-determined threshold S and annotating the EKG signal. The non-discarded portions of the EKG signals having inter-beat variances that exceed V are annotated as atrial fibrillation events.

摘要： A computer method and system synchronizes one streaming data signal with another data signal. A subject data signal and working data signal are received. The working data signal has predefined coordinates in a coordinate system (e.g., time origin and unit sampling rate in a time coordinate system for audio). The subject data signal and working data signal are transformed into respective common representations. An alignment process aligns the respective transformed representations by matching the transformed representation of the working data signal to that of the subject signal. A re-synchronizer element transposes the predefined coordinates of the working data signal onto the subject signal in the aligned state of the respective transformed representations. As such, the subject data signal is synchronized to the coordinate system of the working data signal.
