ABSTRACT
Sixty five anemics and 20 healthy control subjects carefully age and sex matched were subjected to seven standardised tests to evaluate autonomic status. Due care was taken to remove factors which could interfare with the results. Tests concerned with the basal parasympalhetec tone viz heart rate response to standing (p < 0.001) and intravenous atropine test (p < 0.05) showed significant difference which persisted with severity and type of anemia. Test requiring stimulation of the parasympathatic system i.e. deep breathing test, valsalva maneuver and carotid sinus massage did show not significant difference. No difference of significance was found with postural fall of blood pressure and sustained hand grip test, chiefly concerned with the sympathatic system. These results suggest that anemics have low basal parasympathatic outflow to increase the heart rate as compensatory mechanism. Stimulation of parasympathatic and sympathetic system arouse normal response.
