摘要： A subcutaneous and cutaneous electrocardiography monitor configured for self-optimizing ECG data compression is provided. The monitors include a housing, an electrocardiographic front end circuit, a memory, and a micro-controller configured to: obtain a series of electrode voltage values based on the sensed electrocardiographic signals; use a plurality of selection schemes to choose one or more of a plurality of compression algorithms associated with each of the selection scheme for testing; test the selected compression algorithms including applying the compression algorithms chosen using each of the selection schemes to a segment of the electrode voltage series; analyze results of the testing; select one or more compression algorithms chosen using one of the selection schemes for compressing at least a portion of the electrode voltage series based on the analysis; obtain a compression of at least the portion of the electrode voltage series; and store the compression within the memory.

摘要： Improved mapping and ablation procedures and corresponding devices are provided. A variety of methods and apparatuses can be used for the treatment of cardiac arrhythmias by identifying the location of an arrhythmia source and ablating that source. The methods and apparatuses can provide an improved means of electrical mapping of the heart to identify the location of the arrhythmia source and advancing an ablation electrode to that location so that it may be ablated.

摘要： A computer-implemented method includes storing location data for at least one invasive electrode that is movable within a patient’s body. The method also includes storing electrophysiological measurement data representing the electrophysiological signals measured at the outer surface of a patient’s body by body surface electrodes and within the patient’s body by the at least one invasive electrode. The method also includes storing geometry data representing anatomy of the patient spatially, and locations of the respective body surface electrodes and the at least one invasive electrode in three-dimensional space. The geometry data for the at least one invasive electrode can vary based on movement of the at least one invasive electrode within the patient’s body. The method also includes reconstructing electrophysiological signals on a surface of interest within the patient’s body based on the electrophysiological measurement data and the geometry data.

摘要： A system is provided for displaying heart graphic information relating to sources and source locations of a heart disorder to assist in evaluation of the heart disorder. A heart graphic display system provides an intra-cardiogram similarity (“ICS”) graphic and a source location (“SL”) graphic. The ICS graphic includes a grid with the x-axis and y-axis representing patient cycles of a patient cardiogram with the intersections of the patient cycle identifiers indicating similarity between the patient cycles. The SL graphic provides a representation of a heart with source locations indicated. The source locations are identified based on similarity of a patient cycle to library cycles of a library cardiogram of a library of cardiograms.

摘要： A method for using an interactive visual guidance tool for an imaging acquisition and display configured for user navigation with respect to a blockage of a field of view detects, and spatially defines, the blockage. It also integrates, with the image for joint visualization, an indicium that visually represents the definition. The indicium is moved dynamically according to movement, relative to the blockage, of the field of view. The indicium can be shaped like a line segment, or two indicia can be joined in a “V” shape to frame a region of non-blockage. The defining may be based on determining whether ultrasound beams in respective directions are blocked.

摘要： Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration. The systems may generate a cardiogram for each source configuration from the modeled electromagnetic output of that source configuration for use in predicting the source location of an arrhythmia.

摘要： The present invention relates to a method to provide a mean temporal spatial isochrone (TSI) path relating to an ECG feature (wave form) of interest, such as the activation of the heart from a single point (QRS), relative to the heart in a torso while using an ECG measurement from an ECG recording device. The method includes: receiving ECG measuring data from the ECG recording device; determining vector cardiogram (VCG) data; receiving a model of the heart, preferably with torso, as an input, preferably based on a request including request parameters; determining mean TSI data values representing the TSI path relating to an electrophysiological phase representing the ECG feature, the mean TSI providing a location within the heart representing the mean location of the ECG feature at the corresponding time; positioning the mean TSI path and preferably the vector cardiogram data points in the model of the heart and/or torso at an initial position; and rendering the model of the heart, preferably with torso, with the mean TSI path, preferably with VCG data related to the TSI, for displaying on a display screen for interpretation of the displayed rendering.

摘要： A rapid chest pain risk assessment system includes an assessor, a computed tomography (CT) scanner, an electrocardiogram device for providing electrocardiogram related data, and an enzyme analyzer for analyzing the patient's blood. A computer enabled risk calculator categorizes the patients into low, intermediate, and high risk categories. The computer enabled risk calculator, using data from electrocardiogram, blood analyzer and patient's age, other risk factors and history, automatically generates orders for patients in low and intermediate risk categories to undergo a CT scan. A CAC analyzer using the computer file for analyzing the CT scan results then provides a CAC score based on those CT scan results. A risk score based on electrocardiogram, blood analyzer and patient's age, other risk factors and history of symptoms plus the CAC score is generated. Patients that are automatically assessed as being very low risk based on the risk score are recommended for discharge from the emergency room thereby lowering the unnecessary prolonged ER stay time.
