3D Heart Instructional Program for Conduction Defects

描述(由申请人提供)： 该项目的目的是为心脏病专家和参与解释心电图的其他卫生保健专业人员提供一种卓越的教育工具。心电图通常是第一个获得的诊断信息，这种诊断的准确性可以影响患者的存活率。现有的计划提供识别主要类型的心肌梗死的培训：前壁、下壁和后壁。新程序将增加识别各种类型的传导缺陷以及它们在正常12导联心电图机上的表现的能力。这种方法的独特之处在于，它显示了心脏电激活的3个维度的电影，以及在心脏节段形成的电矢量。第二部影片展示了这些矢量如何与三个平面上的矢量信号--额面、水平和矢状面--以及从那里到正常心电图机的12导联之间的关系。这种视觉体验提供了心脏和鸡蛋的物理属性之间的直接关系。在m1的情况下，心肌活动的丧失与该方向上的矢量的损失有直接关系，因此12导联信号中的视觉相关变化。在导电缺陷的情况下，激活波前的投影改变，从而使矢量从法线方向改变。这为心脏病专家提供了一种更准确的评估鸡蛋的方法，并更好地了解了与心脏的关系。该模拟方法提供了心脏激活面的准确再现和心脏每个节段的矢量生成。它还允许3D生成显示心脏活动的电影。在LBBB的情况下，3D图像将显示激活波前从右室间隔表面移动到左室心内膜间隔表面。当激活面围绕左心室从前象限移动到后象限时，这个后方方向继续。所有这些培训计划都将在学生中进行测试，以确定他们就业的好处。

DESCRIPTION (provided by applicant): The objective of this program is to provide a superior educational tool for cardiologists and other health care professionals that are involved in the interpretation of the electrocardiogram. The electrocardiogram is frequently the first diagnostic information that is obtained, and the accuracy of this diagnosis can impact the survival rates of patients. An existing program provides the training for the recognition of the major types of myocardial infarction: Anterior, Inferior, and Posterior. The new program will add the ability to recognize the various types of conduction defects and how they appear on the normal 12-lead electrocardiograph. The uniqueness of this method is that it shows a movie in 3 dimensions of the electrical activation of the heart, along with the electrical vectors that are developed in the heart segments. A second movie shows how these vectors are related to the vector signals in the three planes - frontal, horizontal, and sagittal - and from there to the 12 leads of the normal electrocardiograph. This visual experience provides a direct relationship between the physical properties of the heart and the EGG. In the case of Ml the loss of myocardial activity has a direct relation to the loss of vectors in this direction and thus a visually related change in the 12 lead signals. In the case of conduction defects the projection of the activation wave front is changed so that the vectors are altered from the normal direction. This provides the cardiologist with a more accurate method of evaluation of the EGG and a better understanding of the relation to the heart. The method of simulation provides the accurate rendition of heart activation surfaces and the generation of vectors for each segment of the heart. It also allows the 3D generation of the movies showing the hearts activity. In the case of LBBB, the 3D picture will show that the activation wave front moves from the right ventricular septal surface to the left ventricle endocardial septal surface. This posterior direction continues as the activation surface moves around the left ventricle from the anterior to the posterior quadrants. All of these training programs will be tested with students to determine the benefit of their employment.
