Abstract: A method and system for estimating the extent of ischemia in a test individual using an electrocardiogram (EKG) apparatus. An EKG is obtained from the test individual. A test EKG dataset is obtained comprising EKG measurements from the EKG. The test EKG dataset is converted to a frequency domain. An area under the curve is measured of the test EKG dataset in the frequency domain with respect to a reference EKG dataset comprising EKG measurements in the frequency domain. The area under the curve measurement is normalized to calculate a percentage score value to estimate an extent of ischemia in the test individual.

Abstract: Disclosed includes a body surface device for diagnosing locations associated with electrical rhythm disorders to guide therapy. The device can sense electrical signals and determine multiple sites that may be operative in that patient. The patch may encompass the heart regions from where the heart rhythm disorder originates. The patch comprises an array of electrodes configured to detect electrical signals generated by a heart. A controller may determine the locations of interest based on detected electrical signals. The controller is configured to locate these regions relative to the surface patch. The system may be coupled to a sensor or therapy device inside the heart, to guide this device to a region of interest. The controller is further configured to instruct the operator to use the trigger or source information to treat the heart rhythm disorder in an individual using additional clinical data and methods for personalization such as machine learning.

Abstract: Systems and methods for optimal selection of beats for a 3D mapping are disclosed. A method in accordance with the present disclosure may be performed on a processor and may comprise receiving a plurality of beats from a catheter. The catheter may be located at a target mapping site, such as a chamber of the heart. A plurality of dynamic filters may be applied to the plurality of collected beats. The optimal beats may be determined and integrated as a beat in the 3D mapping system. This method enables the selection of more beats for a more comprehensive 3D mapping, as well as the selection of more quality beats that are representative of the target anatomy.

Abstract: A method enables analysis of (e.g. bioelectric) signals acquired by measurement. The method provides N signals U for an observation space and each has a time- and space-dependent signal characteristic U. Digitized signals for a time period T have M time points and define an M×N matrix with M tuples of N signal values each. Signal values acquired at time t form an N-tuple Ūt=(U1, . . . , UN)t in a signal space. The method acquires all combinations of k tuples from the M tuples, and calculates distances between all tuples. Distance values are calculated and define edge lengths of a (k−1) simplex (SIM) with one simplex assigned to each combination of k time points. Quantity characteristics of the simplex (SIM) are encoded into color values (COL), and displays the colors in a combinatorial time lattice (CTL). Each lattice point (GP) is displayed with the color encoded for the assigned simplex.

Abstract: Electrical ventricular depolarization may be represented by its vectorcardiographic QRS loop, which exists in 3D space. By recognizing that the QRS loop is often a closed trajectory on a plane (2D), it is possible to change (e.g., by rotation, projection, etc.) the single-channel QRS into a different view angle along that plane to provide a viewpoint more favorable for morphologic interpretation. Any monophasic or biphasic single-channel QRS (time series) waveform can be decomposed into the form x(α,t)=sin(αt)u(t), with t spanning [0,2π], where u(t) is an unchanging intrinsic component that is generally upright and monophasic, and where sin(αt) is a changeable component of the waveform. This way, x(α,t) may be changed by replacing a parameter of the original changeable component sin(αt) with a second parameter associated with a target view of the waveform, such as the upright monophasic sin(0.5t). Meanwhile the intrinsic component remains unchanged during this change.
