There are some patients with various equivocal complaints, but without any detected organic damage.
The variation of R-R interval on E. C. G.(C. V.R-R) was measured and investigated if its data was reasonable for diagnosis of such non-organic disease.
Two hundred and twenty four oral surgery patients and 37 healthy volunteers of either sex were examined. The age range was 10 to 79 years old.
The control group did not have any heart disease, autonomic ataxia or non-organic disease. The C.V.R-R of the control group showed decreasing tendency followed with age increase, but no sex difference.
The C.V.R-R of the non-organic group such as the patients who had T.M.J. arthrosis or unidentified complaints revealed lower scores than of the control group. Therefore it was concluded that C.V.R-R is usable to screen non-organic patients.
