Abstract

The physiology of the heart is analyzed by measuring a series of cardiac cycles using a biomagnetometer or other device capable of detecting cardiac cycles, classifying the cardiac cycles into groups according to the degree of correlation with a template cardiac cycle for the group, 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 against which other previously ungrouped cardiac cycles are to be correlated, performing a correlation analysis of all previously ungrouped cardiac cycles with the template cardiac cycle, and associating with the template cardiac cycle all previously ungrouped cardiac cycles having at least a preselected degree of correlation, to form a group.
