Mrs. Emersоn, 35 yeаrs оld, presents with wоrsening bilаterаl finger pain, numbness, and coldness, which she has experienced intermittently for the past 15 years. Bilateral digit PPG pressures and waveforms are obtained both before and after cold stress. Before cold, the waveforms have a sharp upstroke, a narrow peak, and a reflection on the downslope. After cold, the waveforms change to a slow upstroke and downslope, a severely rounded peak, and disappearance of reflection on the downslope. These findings remain for as long as 5 minutes after cold immersion. The postcold waveforms are most consistent with:
