[Diagnostic possibilities of precordial electrocardiographic mapping in the assessment of the results of dipyridamole test in patients with ischemic heart disease].
The dynamics of cross-sectional, isochronic, and integral maps of electric potential distribution during the dipyridamole test was examined in 35 patients with verified coronary heart disease and 12 control patients. Basic differences were found in changes of excitation propagation velocities and positive potential amplitude in the groups examined. A local increase in R wave areas on the maps of positive potential differences was found to be the most significant mapping sign of transient myocardial ischemia (the sensitivity, specificity, and diagnostic accuracy being more than 97%). The diagnostic accuracy of an absolute or relative increase in the integral time and amplitude parameters of the mapping was 77% and 70%, respectively.
