Patient in whom systolic arterial pressure differs by more than 20 mmHg between the right and left arms
Inability to place oscillometric cuff on the subject's upper extremity
Extreme contraction of the smooth muscle in the arteries and arterioles of the lower arm and hand, such as may be present in patients with Raynaud's disease
