Vasomotor Reactions to Heat among Patients with Arterial Disease
Plethysmographic studies of the vasomotor reactions of the digits accompanying body heating were of value in the early detection of peripheral arterial disease. In normal individuals, labile vasomotor activity was shown by great changes in digital volume (a large pulse, alpha and beta waves). These changes were diminished or absent in patients with peripheral arterial disease.
