Paper Title
Three Dimensional Pseudo-Color Display Of Myocardial Ischemia: A New Function Of Twelve Lead ECG

Abstract
A new method is proposed for transforming the ischemic information in the 12 lead electrocardiogram (ECG) to the display of a 3D image in this paper. The ECG signal is sampled by a portable data acquisition device, and the signal features are automatically acquired. The ST-segment deviation is equal to the potential difference of the isoeletric reference point and the detection point of ST-segment determined by the apex of R wave. The ST injury vector is synthesized by the inverse projections of the lead vectors weighted by different coefficients determined by the ST-segment deviation. The location and the scope of ischemic region are displayed with different color coding by projecting the ST injury vector on a 3D heart model. Experimental results show that the proposed method is of high reference value in locating the ischemic region, and is highly consistent with several currently accepted methods in the diagnosis of myocardial ischemia. Index- Terms:ischemia display, ST injury vector, ST-segment deviation, vector projection
