Embodiment Construction

[0020] A method and system for signal processing are disclosed herein. More specifically, the present invention relates to signal analysis of movement of a reference electrode of a catheter in a coronary sinus (CS) vein.

[0021] For example, a device-oriented engine is processor-executable code or software that must be rooted in the process operations performed by the medical device device as well as in the processing hardware of the medical device device. According to an exemplary embodiment, the device orientation engine may include a machine learning / artificial intelligence (ML / AI) algorithm. The device orientation engine tracks the movement of the CS catheter within the CS while mapping the CS. For example, the device orientation engine tracks the movement of the CS catheter along the axial axis of the CS (which can affect the stability of the map's reference), and tracks deviations from the acquired reference position at the beginning of the mapping.

Abstract

The invention relates to signal analysis of movement of a reference electrode of a catheter in a coronary sinus vein. A method is provided. The method is implemented by a device orientation engine executed by one or more processors. The method includes determining movement between each electrode set of the catheter to provide movement, and determining a total movement of the electrodes of the catheter. The method also includes removing a standard component from the movement and the total movement, and outputting a movement indication of the catheter based on the movement and the total movement using the standard component.

Description

technical field [0001] The present invention relates to a method and system for signal processing. More specifically, the present invention relates to signal analysis of movement of a reference electrode of a catheter in a coronary sinus (CS) vein. Background technique [0002] Currently, cardiac electrophysiology systems are used to map or visualize the real-time calculated position and orientation of a catheter within a patient's heart. In some cases, the cardiac electrophysiology system utilizes reference time points to visualize activation waves on the heart between different heartbeats or for each point acquired during the mapping process. Additionally, the cardiac electrophysiology system can track time with respect to a reference point. [0003] In general, the CS vein is an excellent reference point for the cardiac electrophysiological system because the CS vein is located between the atria and ventricles (eg, this means that the catheter can monitor atrial and ven...
