Abstract: The physiological behavior of the heart is analysed by measuring (62) and storing (64) a series of cardiac cycles, classifying the cardiac cycles into groups according to the degree of correlation with a template cardiac cycle (66), and associating the cardiac cycles of the groups with an origin location within the subject. The classifying operation preferably includes selecting a template cardiac cycle (66) against which other previously ungrouped cardiac cycles are to be correlated, performing a correlation analysis (68) of all previously ungrouped cardiac cycles with the template cardiac cycle using a selectable degree of correlation (70), and associating with the template cardiac cycle (66) all previously ungrouped cardiac cycles (72) having at least a preselected degree of correlation, to form a group. The classifying operation is iteratively repeated until all cardiac cycles are classified into appropriate groups.
