摘要： A signal analysis device includes a biological information acquisition unit that acquires a waveform of a time section of an R wave included in a waveform for one cycle indicating a cardiac cycle of a heart of an analysis target as a target time waveform, and an analysis unit that, upon approximating the target time waveform by an approximate time waveform that is a time waveform obtained by a difference or a weighted difference between a first cumulative distribution function and a second cumulative distribution function, or upon approximating the target time waveform by an approximate time waveform that is a time waveform obtained by adding a level value to a difference or a weighted difference between a first cumulative distribution function and a second cumulative distribution function, acquires at least one of at least some parameters of parameters identifying a first unimodal distribution, at least some parameters of parameters identifying the first cumulative distribution function, at least some parameters of parameters identifying a second unimodal distribution, or at least some parameters of parameters identifying the second cumulative distribution function as a parameter indicating activity of a myocardium of the heart.

摘要： An apparatus comprising at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to acquire a heart activity measurement signal of a user, wherein the heart activity measurement signal characterizes electric activity of a heart measured by at least one electrode pair in contact with the user's skin; compute an auxiliary signal approximating a wavelet transform of the heart activity signal; compute a phase of the heart activity measurement signal by computing an argument of the auxiliary signal; determine interference signal components in the acquired heart activity signal on the basis of the phase of the heart activity measurement signal; and eliminate the determined interference signal components from further analysis of the heart activity measurement signal.

摘要： A method includes defining multiple different types of arrhythmias. Similarity measures are defined for the types of arrhythmias. A set of EP signals is received, the set acquired in a heart of a patient. Using the similarity measures, the set of EP signals is partitioned into at least two clusters, each cluster containing EP signals complying with a respective similarity measure for a respective type of arrhythmia. The clusters are indicated to a user.

摘要： A method and apparatus for the quantitative determination of an individual's risk for sudden cardiac death (SCD) is described. Risk determination is accomplished and may have a sensitivity and specificity of greater than 95%, by generating linear and nonlinear mathematical digital ECG-constructed models from digital ECG-type data of an individual's digital ECG, determining stability/instability of digital ECG-constructed control model systems corresponding to the digital ECG-constructed models by a plurality of techniques and transforming stability/instability values obtained by the determining stability/instability into a quantitative value reflecting an individual's risk for SCD.

摘要： A method includes obtaining multiple local activation times (LATs) at different respective measurement locations on an anatomical surface of a heart. The method further includes computing respective directions of electrical propagation at one or more sampling locations on the anatomical surface, by, for each sampling location, selecting a respective subset of the measurement locations for the sampling location, constructing a set of vectors, each of at least some of the vectors including, for a different respective measurement location in the subset, three position values derived from respective position coordinates of the measurement location and an LAT value derived from the LAT at the measurement location, and computing the direction of electrical propagation at the sampling location based on a Principal Component Analysis (PCA) of a 4x4 covariance matrix for the set of vectors. The method further includes indicating the directions of electrical propagation on a display.
