Abstract
A computer-implemented method for analyzing a physiological signal includes selecting a first time interval containing a pattern of interest in a recording of the physiological signal. Respective values of a characteristic of the physiological signal are computed in a plurality of time segments within the first time interval. The computed values are concatenated to form a signature of the pattern of interest. A further occurrence of the pattern of interest is identified in the physiological signal during a second time interval by matching the signal in the second time interval to the signature.
Claims25
A computer-implemented method for analyzing a physiological signal, comprising:
- selecting a first time interval containing a pattern of interest in a recording of the physiological signal;
- computing respective values of a characteristic of the physiological signal in a plurality of time segments within the first time interval;
- concatenating the computed values to form a signature of the pattern of interest;
- and
- identifying a further occurrence of the pattern of interest in the physiological signal during a second time interval by matching the signal in the second time interval to the signature.
Apparatus for analyzing a physiological signal, comprising:
- an input device, which is arranged to accept a selection of a first time interval containing a pattern of interest in a recording of the physiological signal;
- and
- a processor, which is arranged to compute respective values of a characteristic of the physiological signal in a plurality of time segments within the first time interval, to concatenate the computed values to form a signature of the pattern of interest, and to identify a further occurrence of the pattern of interest in the physiological signal during a second time interval by matching the signal in the second time interval to the signature.
A computer software product for analyzing a physiological signal, the product comprising a computer-readable medium, in which program instructions are stored, which instructions, when read by a computer, cause the computer to accept a selection of a first time interval containing a pattern of interest in a recording of the physiological signal, to compute respective values of a characteristic of the physiological signal in a plurality of time segments within the first time interval, to concatenate the computed values to form a signature of the pattern of interest, and to identify a further occurrence of the pattern of interest in the physiological signal during a second time interval by matching the signal in the second time interval to the signature.
