摘要： 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.

摘要： A method includes receiving intracardiac electrogram (IEGM) signals measured at a plurality of locations in a region of a heart that contains a His bundle of the heart. The IEGM signals are processed to find respective local activation time (LAT) values. A cluster of the locations is identified at which peaks associated with the LAT values occur later than a defined time. Respective time differences are calculated between times of occurrence of the associated peaks and a reference time. The time differences are compared to a threshold value to retain locations for which the time differences are below the threshold value. The respective IEGM signals are filtered to identify respective high-frequency peaks in the IEGM signals. The high-frequency peaks are cross-corelated to identify a subset of the locations whose high-frequency peaks meet a predefined cross-correlation level. The high-frequency peaks are tagged as His peaks and indicated on a cardiac map.

摘要： In one embodiment, a method to determine reliable electrocardiogram (ECG) signal is described. The method includes receiving at least one ECG signal for a period of time from a patient. The method also includes analyzing the at least one ECG signal to determine a first heart rate using a first method and analyzing the at least one ECG signal to determine a second heart rate using a second method different from the first method. The method includes comparing the first and second heart rates to each other and classifying the at least one ECG signal as reliable when a reliability threshold is satisfied.

摘要： 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.

摘要： 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.

摘要： Cardiac activity (e.g., a cardiac electrogram) is analyzed for local abnormal ventricular activity (LAVA), such as by using a LAVA detection and analysis module incorporated into an electroanatomical mapping system. The module transforms the electrogram signal into the wavelet domain to compute as scalogram; computes a one-dimensional LAVA function of the scalogram; detects one or more peaks in the LAVA function; and computes a peak-to-peak amplitude of the electrogram signal. If the peak-to-peak amplitude does not exceed a preset amplitude threshold, then the module can compute one or more of a LAVA lateness parameter for the electrogram signal using one of the one or more peaks detected in the LAVA function and a LAVA probability parameter for the electrogram signal.
