Integralheart three-dimensional mapping system for complex arrhythmias

Abstract

The invention discloses an integralheart three-dimensional mapping system for complex arrhythmias. The system comprises an epicardial three-dimensional mapping module, an endocardial three-dimensional magnetic localization mapping module, an endocardial epicardial mapping module and a three dimensional mapping common basic module, wherein, the three dimensional mapping common basic module provides the construction of the three dimensional anatomical model of heart and the fusion between electrophysiological information and the anatomical model; the endocardial three-dimensional magnetic localization mapping module is embedded with magnetic field generation and localization hardware to provide the magnetic field localization for the whole system. The epicardial mapping module is embedded with epicardial segmentation software; the endocardial epicardial mapping module is embedded with endocardial epicardial combined mapping algorithms to achieve the integral heart mapping. The integralheart three-dimensional mapping system for complex arrhythmias can organically fuse the three-dimensional electro-anatomical information mapped collectively by the endocardium and the corresponding epicardium to achieve the accurate mapping in the situations of both the fixed heart shape and position and the dynamic conditions of chest opening, and therefore the requirement of clinical diagnosis and treatment and the mechanism research of the arrhythmias can be satisfied.

Description

technical field [0001] This application is an overall heart three-dimensional mapping system for clinical diagnosis, treatment and mechanism research of complex arrhythmia. Using this system, the three-dimensional electroanatomical mapping information of the endocardium and its corresponding epicardium can be obtained, and the two can be organically fused to realize endocardial mapping when the position and shape of the heart are relatively fixed. Accurate epicardial mapping can be performed when the position and shape of the heart change, such as open chest, to complete the overall three-dimensional mapping of the heart, and to meet the unique needs of complex arrhythmias. It belongs to the technical field of medical equipment. Background technique [0002] Arrhythmia is a common clinical cardiovascular disease. Complex arrhythmias such as atrial fibrillation, ventricular tachycardia, and ventricular fibrillation seriously endanger human health and have become the focus of...

AI Technical Summary

Problems solved by technology

The main reason is that epicardial mapping is usually carried out under direct vision of the open heart. At this time, the electric field medium changes due to air filling, and the shape and position of the heart will also change due to surgical traction. Ensite system and Carto system Neither can be used in this case

[0004] The two-dimensional mapping technology under traditional X-ray fluoroscopy can be used for thoracotomy epicardial mapping, but because the spatial display is not intuitive, this method has defects such as difficulty in accurate positioning, long X-ray exposure time, and no positioning , memory function, difficult to meet the research needs of complex arrhythmia

[0005] The multi-channel electrophysiological mapping technology applied clinically in the 1990s, with the aid of computers, can simultaneously obtain ECG signals at multiple sites by placing multiple electrodes on the epicardial surface at the same time, with high accuracy. However, it is still two-dimensional mapping, which lacks intuition, and it is difficult to combine it with intracardiac mapping to analyze the corresponding regions. Most of them adopt offline analysis, and the analysis results cannot be obtained in real time, so the clinical application is limited.

[0006] Optical mapping technology is a functional imaging technology to study the conduction of cardiac electrical excitation at the cellular level. Toxicity, etc., this technology is currently mainly used for in vitro mapping of animals, and it is difficult to use in humans

[0007] Therefore, the existing two-dimensional and three-dimensional mapping systems cannot well meet the unique clinical diagnosis, treatment and mechanism research needs of complex arrhythmias.
