Embodiment Construction

[0020] In the following detailed description, numerous specific details are shown in order to provide a thorough understanding of the various principles of the invention. It will be apparent to those skilled in the art, but not all of these details are necessary to practice the invention. In this instance, well-known circuits, control logic components, and details of computer program instructions for conventional algorithms and processes have not been shown in detail to avoid unnecessarily obscuring general concepts.

[0021] Aspects of the present invention can be embodied in software programming code, typically maintained in a persistent storage device such as 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 for use with data processing systems, such as USB memory, hard drives, electronic ...

Abstract

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.

Description

technical field [0001] The present invention relates to medical imaging systems. More specifically, the present invention relates to operator interfaces in medical imaging systems. Background technique [0002] Cardiac arrhythmias, such as atrial fibrillation, occur when regions of heart tissue abnormally conduct electrical signals to adjacent tissue, disrupting the normal cardiac cycle and making the heart arrhythmia. [0003] Electrical activity in the heart is typically measured by advancing a multi-electrode catheter to simultaneously measure electrical activity at multiple points in the chambers of the heart. Graphical user interfaces integrated with modern imaging systems for monitoring cardiac catheterization present rich and dynamic information from multiple electrodes to the operator and facilitate efficient processing of the information. [0004] A complication of receiving an atrial electrogram signal from an intracardiac catheter is the undesirable mixing of fa...
