EnSite新型心脏绘图工具

 
一种在电生理治疗新型分割工具和计算机为基础的系统，使得治疗不规则心跳的方法变得更加容易，这种系统已经研制开发用于电生理治疗中加快速度以及增加观察和导航的便利性。

“EnSite系统5.1版的引入，是3D [三维]导航和观察技术的重要进步，” Jane J. Song如此评论说，他是St. Jude医疗心房纤颤分部的总裁 (St. Paul, MN, USA)。 “与EnSite Verismo分割工具配套使用，这将为临床

医生提供更多的临床应用价值，主要通过增加治疗的速度、使用便利性和可操控性。这些特性是有效的EP治疗的重要组成部分。”

EnSite 5.1软件具有多点工艺，其设计目的是增加心脏绘图的速度和效率。EnSite Verismo分割工具使用CT和核磁共振扫描来建立3D心脏模型，能够在治疗设计、几何模型建立、以及治疗输送的有效性方面

起到辅助作用。EnSite系统包含在2005年1月St. Jude医疗心脏内解决方案之中(ESI; St. Paul, MN, USA)。

使用EnSite系统，电生理医生能够在EP治疗过程中，创建患者心脏解剖学的3D模型，在治疗过程中引导导管的走向。该系统收集并组织心脏内壁的激活和电压，使得医生能够在3D模型上观察心率不齐，并

确定治疗策略。

Cardiac Mapping Tools
 
A new segmentation tool for use during electrophysiologic (EP) procedures and a computer-based system to facilitate procedures to treat irregular heartbeats have been developed to enhance speed and

flexibility of visualization and navigation during EP procedures.

“The introduction of EnSite system version 5.1 is a significant advance in 3D [three-dimensional] navigation and visualization technology,” said Jane J. Song, president of the St. Jude Medical atrial fibrillation

division (St. Paul, MN, USA). “Combined with the EnSite Verismo segmentation tool, this upgrade will provide greater clinical value for physicians through increased speed, flexibility, and control during

procedures. These capabilities are a crucial part of effective EP procedures.”

The EnSite 5.1 software features MultiPoint technology, which is designed to increase the speed and efficiency of cardiac mapping procedures. The EnSite Verismo segmentation tool uses computed tomography

(CT) and magnetic resonance imaging (MRI) scans to construct 3D cardiac models that assist in procedure planning, geometry creation, and validation of therapy delivery. The EnSite system was included in St.

Jude Medical’s acquisition of Endocardial Solutions, Inc. (ESI; St. Paul, MN, USA) in January 2005.

Using the EnSite system, electrophysiology clinicians can create 3D models of their patients’ cardiac anatomy during EP procedures and navigate the catheters used in those procedures. The system then

collects and organizes activation and voltage data from the inner surface of the heart, allowing physicians to visualize arrhythmias on the 3D model and determine a treatment strategy.
