AB  - Body surface mapping (map) was used to evaluate various cardiac diseases
      quantitatively. For 30 cases with old anterior myocardial infarction (AMI), map
      parameters were compared with infarct size assessed by left ventriculography and 
      201Tl myocardial scintigraphy (LV% asynergy and 201Tl% defect, respectively).
      Parameters used in the present study were nSubtraction 40 (sigma Subtr. 40),
      which were obtained by the summation of voltages less than the lower limit of
      normal range (mean--2SD) at 40 msec from the QRS onset and nSubtraction 10-60
      (sigma Subtr. 10-60), which was obtained by the integral of voltages below the
      normal range, calculated each 10 msec to 60 msec, as well as the number of lead
      points with Q waves of 30, 40 msec duration (nQ30, nQ40), and the summation of R 
      voltages over the entire body surface (sigma R). In 19 cases with aortic
      regurgitation (AR), R and S voltages in each lead were compared with left
      ventricular diastolic dimension (LVDd) obtained by echocardiography. In 43
      healthy persons and two patients with RV pacing, the ventricular activation time 
      was measured in each lead (VAT map). In AMI, nSubtr. 40 correlated best with LV% 
      asynergy (r = 0.70, p less than 0.001). EF and 201Tl% defect were related to
      nSubtr. 10-60 (r = 0.83, p less than 0.001 and r = 0.85, p less than 0.001,
      respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
