HIGH RESOLUTION ELECTROMECHANICAL MAPPING OF THE HEART

心脏的高分辨率机电标测我们已经开发了硬件、MR脉冲序列和数据分析软件，以执行高分辨率的机械功能标测，同时记录心脏周围电极的电激活标测。电子记录系统已经与MR兼容，因此MR图像质量不会因为心脏周围存在袜子而降低。通过将电子地图与由MRI标记研究产生的机械地图配准来生成耦合的机电激活地图。现在可以详细研究缺血对机电系统的影响，或许可以精确区分存活和死亡的组织。

HIGH RESOLUTION ELECTROMECHANICAL MAPPING OF THE HEART We have developed the hardware, MR pulse sequences and data analysis software to perform high resolution mechanical function maps while simultaneously recording electrical activation maps from an electrode "sock" surrounding the heart. The electrical recording system has been made MR compatible so that the MR image quality is not degraded by the presence of the sock around the heart. Coupled electromechanical activation maps are being generated by registration of the electrical maps with the mechanical maps generated from MRI tagging studies. The effect of ischemia on the electromechanical can now be studied in detail, perhaps leading to the ability to precisely distinguish viable from non-viable tissue.
