We evaluated the validity of body surface mapping (MAP) in assessing noninvasively the degree of myocardial ischemia in patients with significant coronary arterial stenosis following Kawasaki disease. Delay of ventricular depolarization was examined by a departure map (DM) using mean QRS map, and the sensitivity of this method in detecting myocardial ischemia was evaluated based on the findings of coronary arteriography (CAG). The other noninvasive measures were also evaluated. MAP was obtained in 29 patients with significant coronary arterial stenotic lesions, including coronary occlusion, segmental stenosis and localized stenosis of 75% or greater. Mean QRS map was obtained based on MAPs in 41 children without organic heart disease and in 22 patients with significant stenotic lesions. The departure index (DIi) was calculated by subtracting potentials at each lead from those of the mean QRS maps and divided by the standard deviation. Departure area (Da) was defined as an area with DIi of -2 or less. Each MAP was subdivided into nine sections, and Da greater than or equal to one-eighth of the anterior wall section, Da greater than or equal to one-third of the posterior and inferior wall sections or Da greater than or equal to half of the other sections were regarded as ischemic areas. Sensitivity in detecting ischemia by MAP was assessed by the CAG findings, which was also compared to the sensitivity of the electrocardiograms (ECG), ECG with dipyridamole administration (Dp-ECG), vectorcardiograms (VCG), Holter ECG (Holter), treadmill test (TM), Master's double step test (MD), two-dimensional echocardiography (2DE) and thallium myocardial imaging (TMI).(ABSTRACT TRUNCATED AT 250 WORDS)
