Abstract
Three-dimensional electrogram was used for analysis of ischemia
manifestation in isolated hearts. Three parameters based on
spherical coordination system were used in this study –
amplitude of electrical heart vector, its azimuth and elevation.
The parameters were presented as a trend. This approach
reflected ischemic changes in a manner which can be easily
observed and evaluated. Ischemia was analysed in seven isolated
hearts of New Zealand white rabbits. It was found that (a)
ischemia changes heart electric vector, (b) ischemic
preconditioning has a protective effect, and (c) both of these
findings can be clearly observed by the proposed method.
