Cardiac magnetic field diagnosing apparatus by late ventricular potential and method of locating intramyocardial excitement uneven propagation portion |
摘要 |
A magnetic field distribution measurement device (1) provides a non-contact magnetic measurement on a subject's chest at a plurality of coordinates and forms therefrom time-series magnetic field distribution data. A first arithmetic device (2) in response generates image data representing an intramyocardial excitation conduction rate. A second arithmetic device (3) receives a plurality of tomographic image data separately obtained by a tomographic diagnosis apparatus and processes the data to generate three-dimensional, anatomical image data. A display device (4) receives these data and displays on an anatomical image an image representing an intramyocardial excitation current. This can facilitate identifying an anatomical, positional relationship of a ventricular late potential caused in heart muscle. Furthermore, the anatomical image may be replaced with an image representing a normal stimulation conduction path and serving as a template. |
