Abstract: A system includes an interface and a processor. The interface is configured to receive, from at least first and second electrodes of a catheter, first and second signals, respectively, which are acquired over at least a time interval by the at least first and second electrodes at an organ of a patient. The processor is configured to produce a three-dimensional (3D) representation of at least a portion of the catheter and first and second traces corresponding to the first and second signals, and the first and second traces are displayed in a 3D space relative to physical positions of the first and second electrodes on the catheter, respectively.

Abstract: In one embodiment, a system includes a catheter, at least one position sensor to provide position signal(s) indicative of a position of a distal end of the catheter over time, a first smoothing filter to provide first filtered position signal(s) responsively to the position signal(s) and a first filtering level, a second smoothing filter to provide second filtered position signal(s) responsively to the position signal(s) and a second filtering level, wherein the second filtering level provides more smoothing than the first filtering level, and processing circuitry to find first and second position coordinates of the distal end responsively to the first and second filtered position signal(s), respectively, generate, and render to a display, an anatomical map of a body part responsively to the second position coordinates, and render a representation of the distal end to the display while showing movement of the distal end responsively to the first position coordinates.

Abstract: 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.
