摘要： An apparatus includes a shaft and an end effector at a distal end of the shaft. The end effector is sized to fit in an anatomical passageway within a subject's cardiovascular system. The end effector includes at least one electrode pair that is configured to contact cardiovascular tissue and thereby pick up electrocardiogram signals. Each electrode pair includes first and second electrodes spaced apart along a longitudinal axis from each other by a gap area located between the electrodes, the gap area having a gap length with respect to the longitudinal axis such that a length of one of the electrodes along the longitudinal axis is equal to or greater than the gap length; and a ratio of an area defined by the gap area to one electrode area is equal to or less than one.

摘要： An apparatus includes a frame and a plurality of magnetic field generators. The frame is configured to be secured to a patient's head. The frame includes a plurality of housings. Each housing of the plurality of housings is configured to securely engage a corresponding portion of the patient's head. The plurality of magnetic field generators is operable to generate a magnetic field around at least a portion of the patient's head. Each magnetic field generator of the plurality of magnetic field generators is securely retained by a corresponding housing of the plurality of housings.

摘要： A method, consisting of modeling physical parameters representative of a probe in proximity to body tissue during an ablation procedure performed by the probe. The method also includes measuring a subgroup of the physical parameters during a non-ablation stage of the ablation procedure so as to generate measured non-ablative values of the subgroup, and measuring the subgroup of the physical parameters during an ablation stage of the ablation procedure so as to generate measured ablative values of the subgroup. In response to the modeling, the method includes generating calculated non-ablative values of the subgroup for the non-ablation stage, and generating calculated ablative values of the subgroup for the ablation stage. The method compares the measured non-ablative values with the calculated non-ablative values, and compares the measured ablative values with the calculated ablative values, so as generate optimal values of the physical parameters.

摘要： A method includes, in a processor, receiving example representations of geometrical shapes of a given type of organ. In a training phase, a neural network model is trained using the example representations. In a modeling phase, the trained neural network model is applied to a set of location measurements acquired in an organ of the given type, to produce a three-dimensional model of the organ.

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： Medical apparatus and methods for diagnostic and site determination of cardiac arrhythmias within a heart of a subject are provided. A computing device receives, records and processes electrocardiogram (ECG) signals in the form of bipolar and unipolar ECGs associated with respective cardiac tissue locations corresponding to catheter distal end sensors on locations. Unipolar ECGs that include signals from a plurality of successive heartbeats corresponding to locations within an area of study are analyzed to identify Fractionated Unipolar ECG Signal Complexes (FUESCs) of unipolar ECGs by defining complexes of the unipolar ECGs that correspond to respective bipolar activity windows. Identified arrhythmia sites for treatment include a predetermined number of unipolar ECGs that have a predetermined number of FUESCs. Atrial arrhythmia sites for treatment by ablation can be identified with respect to FUESCs of unipolar ECGs that include signals from at least ten successive heartbeats of an atrial tissue study area.

摘要： Classification of heartbeats based on intracardiac and body surface electrocardiogram (ECG) signals are provided. Intracardiac ECG (IC-ECG) signals and body surface ECG (BS-ECG) signals are processed to perform heartbeat classifications. A BS annotation of BS-ECG signals reflective of a sensed heartbeat is defined, the BS annotation including a BS annotation time value. IC annotations of IC-ECG signals which reflect atrial-activity or ventricular activity of the sensed heartbeat are also defined, each IC annotation including an IC annotation time value. The IC-ECG signals are discriminated as A-activity or V-activity and IC annotations are designated as IC-A annotations or IC-V annotations, respectively. A respective A/V time sequence comparison of IC annotations reflective of the sensed heartbeat is made with one or more time sequence templates for heartbeat classification. Morphology comparisons of the BS-ECG oscillating signal segments reflective of the sensed heartbeat morphology templates for classification may also be made.
