PG - 705-13 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) FAU - Ishikawa, T AU - Ishikawa T FAU - Hayashi, H AU - Hayashi H FAU - Miyachi, K AU - Miyachi K FAU - Takami, K AU - Takami K FAU - Yabe, S AU - Yabe S FAU - Osugi, S AU - Osugi S FAU - Sotobata, I AU - Sotobata I LA - jpn PT - English Abstract PT - Journal Article PL - Japan TA - J Cardiogr JT - Journal of cardiography JID - 7801085 SB - IM MH - Adolescent MH - Adult MH - Aortic Valve Insufficiency/diagnosis MH - Electrocardiography/*methods MH - Female MH - Heart Diseases/*diagnosis MH - Humans MH - Male MH - Middle Aged MH - Myocardial Infarction/diagnosis EDAT- 1985/09/01 00:00 MHDA- 1985/09/01 00:01 CRDT- 1985/09/01 00:00 PHST- 1985/09/01 00:00 [pubmed] PHST- 1985/09/01 00:01 [medline] PHST- 1985/09/01 00:00 [entrez] PST - ppublish SO - J Cardiogr. 1985 Sep;15(3):705-13.
