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 an example, a method includes receiving a cardiac signal that is sensed by an electrode at a tissue location inside the heart. Fractionations are identified in the cardiac signal. The fractionations identified at the tissue location are compared between first and second cardiac cycles of the cardiac signal. Based on the comparing, a likelihood is estimated, that the tissue location is causing a stable arrhythmia. Based on the estimated likelihood, the tissue location is indicated to a user as likely to be causing the stable arrhythmia.

Abstract: A computer system, processor, programming instructions and/or method for balancing the workload of processing pipelines that includes an execution slice, the execution slice comprising at least two processing pipelines having one or more execution units for processing instructions, wherein at least a first processing pipeline and a second processing pipeline are capable of executing a first instruction type; and an instruction decode unit for decoding instructions to determine which of the first processing pipeline or the second processing pipeline to execute the first instruction type. The processor configured to calculate at least one of a workload group consisting of: the first processing pipeline workload, the second processing pipeline workload, and combinations thereof; and select the first processing pipeline or the second processing pipeline to execute the first instruction type based upon at least one of the workload group.
