Figure 1 (A) In healthy controls, photoplethysmographic pattern is homogeneous, and sphygmic wave amplitude is high. (B) In patients with systemic sclerosis, photoplethysmographic pattern is dyshomogeneous, and sphygmic wave amplitude is reduced. (C) in patients with Raynaud phenomenon, photoplethysmographic pattern is homogeneous, and sphygmic wave amplitude is markedly reduced.
