摘要： Methods, apparatus, and systems for medical procedures are disclosed herein and include a catheter having a first electrode and a second electrode, the first electrode configured to transmit first electromagnetic signals and the second electrode configured to transmit second electromagnetic signals. A first patch, a second patch, and a third patch each configured to receive the first and second electromagnetic signals are included and arranged in a triangular formation on a first surface of a patient's body. A first catheter position relative to the first patch, the second patch, and the third patch, is determined at a first time and a second time. The first catheter position and the second catheter position relative to the first catheter position may be displayed such that the first catheter position is visually connected to the second catheter position.

摘要： Methods, apparatus, and systems for medical procedures include receiving a first ultrasound slice from an ultrasound transducer, the first ultrasound slice corresponding to a first ultrasound position. A second ultrasound slice is received from the ultrasound transducer, the second ultrasound slice corresponding to a second ultrasound position. The first ultrasound slice and the second ultrasound slice are stored in memory. A first catheter position of a catheter is received. The first catheter position is determined to correspond to the first ultrasound position and the first ultrasound slice is provided based on the determination. The determination that the first catheter position corresponds to the first ultrasound position may be made based on locations, orientations, or may be based on the number of voxels that overlap between the first catheter position and ultrasound positions.

摘要： Described embodiments include a system that includes an electrical interface and a processor. The processor is configured to receive, via the electrical interface, an electrocardiographic signal from an electrode within a heart of a subject, to ascertain a location of the electrode in a coordinate system of a computerized model of a surface of the heart, to select portions of the model responsively to the ascertained location, such that the selected portions are interspersed with other, unselected portions of the model, and to display the model such that the selected portions, but not the unselected portions, are marked to indicate a property of the signal. Other embodiments are also described.

摘要： A system includes multiple electrically-conductive channels and a processor. The processor is configured to receive, over the electrically-conductive channels, (i) respective first electric currents from a probe, which is within a body of a patient, via a plurality of first electrodes, which are attached to skin of the patient at a region of the body, and (ii) a second electric current from the probe via a second electrode, which is attached to the skin and is connected to one of the channels. The processor is further configured to ascertain respective first electric-current values of the first electric currents and a second electric-current value of the second electric current, and to calculate a position of the probe between the region and the second electrode, based on the first electric-current values and the second electric-current value. Other embodiments are also described.

摘要： An apparatus includes a shaft, a flexible distal-end assembly, two or more sensing-electrodes, and a fiber-optic shape sensor. The shaft is configured for insertion into a body of a patient. The flexible distal-end assembly is fitted at a distal end of the shaft. The two or more sensing-electrodes are disposed over the distal-end assembly and are configured to generate signals indicative of positions of the sensing-electrodes in the body. The fiber-optic shape sensor is coupled to a portion of the distal-end assembly, wherein the two or more sensing-electrodes have α-priori known distances from a known location over the fiber-optic shape sensor, and wherein the fiber-optic shape sensor is configured to provide an indication of a spatial deformation of the flexible distal-end assembly.

摘要： Cardiac catheterization is carried out using a probe having sensing electrodes disposed on a distal portion thereof, placing the sensing electrodes in galvanic contact with respective locations in an atrium of the heart, thereafter acquiring electrograms from the sensing electrodes while concurrently detecting ventricular depolarization events, generating from the electrograms a time-varying electroanatomic map showing electrical propagation in the heart, and displaying the electroanatomic map in a series of visual images, the images including an icon that visually indicates the ventricular depolarization events.
