Embodiment Construction

[0024] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the various principles of the invention. However, it will be apparent to those skilled in the art that not all of these details are always necessary to practice the invention. In this case, well-known circuits, control logic and computer program instruction details for conventional algorithms and processes have not been shown in detail in order not to unnecessarily obscure the main concepts.

[0025] Aspects of the present invention can be embodied in software programming code, typically maintained in persistent storage (eg, a computer readable medium). In a client / server environment, such software programming code can be stored on either the client or the server. The software programming code can be embodied on any of a variety of known non-transitory media (eg, floppy disks, hard drives, electronic media, or CD-ROMs) for use with data processing syste...

Abstract

Methods and systems for mapping cardiac electrical activity employ a cardiac catheter having a plurality of spines mounted at the distal end, each spine having a plurality of electrodes. Electrical signal data are obtained from the heart via the electrodes, and respective intracardiac locations and orientations of the spines are sensed. An electroanatomic map of the heart is derived from the signal data, and presented as a graphic representation of the respective intracardiac locations and orientations of the spines, with distinctive graphical indicia of at least portions of the spines. The method is further carried out by displaying the electroanatomic map, and responsively to the displayed electroanatomic map, adjusting at least one of the locations and orientations of at least one of the spines.

Description

technical field [0001] The present invention relates to invasive medical devices. More specifically, the invention relates to monitoring electrical activity within the heart with invasive probes. Background technique [0002] Cardiac arrhythmias, such as atrial fibrillation, occur when regions of heart muscle tissue abnormally conduct electrical signals to adjacent tissues, disrupting the normal cardiac cycle and causing asynchronous heart rhythms. [0003] Surgery to treat cardiac arrhythmias involves surgically disrupting the source of the signal causing the arrhythmia, as well as disrupting the conduction pathways for such signals. By selectively ablating heart tissue by applying energy through a catheter, it is sometimes possible to stop or alter the propagation of unwanted electrical signals from one part of the heart to another. Ablation methods destroy useless electrical pathways by creating non-conducting dysfunctions. [0004] Mapping of intracardiac potentials i...
