Problems solved by technology

Also, if the diagnostic plot has animated graphics, the user may not be able to see all of the graphic at the same time, since the animation will occur on the entire model (background and foreground) as the model rotates
Therefore, certain diagnostic map features and patterns may be difficult to identify using a 3D geometric model of the heart

Embodiment Construction

[0025] figure 1 is a schematic representation of the medical imaging system 10 for determining the position of the catheter 12 relative to the organ model of the patient 14 and for generating and displaying this model and related information on the display unit 16 . System 10 includes: mobile imager 18, which includes intensifier 20 and transmitter 22; and magnetic positioning system 24, which includes positioning sensor 26 (which may be referred to as a position sensor and which may include, for example, one or more coil) and field generator 28. Information from the electrophysiological map and cardiac mechanical activation data associated with the model generated by the medical imaging system 10 is displayed on a computer display 16 to facilitate treatment and diagnosis of the patient 14 . This disclosure describes a method that enables system 10 to collect and synthesize large amounts of information into an easily understandable format to facilitate diagnosis and treatmen...

Abstract

A system for displaying a mechanical activation pattern of a heart includes a data input, a processor, and an output. The data input is adapted to receive data from an electrophysiology device. a processor electrically connected to the data input and configured to: calculate a mechanical activation parameter from the data; generate an anatomical representation of the heart from the data; divide the anatomical representation into segments; and generate a depiction showing magnitude of the mechanical activation parameter relative to the segments , so that the performance of multiple segments can be evaluated simultaneously. The output is suitable for sending a depiction to a display.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Application Serial No. 61 / 983,221 filed April 23, 2014, which is hereby incorporated by reference as if fully set forth. This application is related to US Provisional Application Serial No. 61 / 988,779 filed May 4, 2015, which is hereby incorporated by reference as if fully set forth. technical field [0003] The present disclosure relates to electrophysiology devices for measuring electrical and mechanical activity occurring in a patient's heart and for visualizing that activity and / or information related to that activity in a three-dimensional (3D) model. In particular, the present disclosure relates to displaying mechanical activation patterns determined by electrophysiological devices in an advantageous format that facilitates data interpretation. Background technique [0004] The heart contains two special types of cardiomyocytes. The majority (ninety-nine percent or so) of cardi...
