Quincke's Pulse: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Aortic Regurgitation:
Poor sensitivity and specificity - this finding merely reflects wide pulse pressure. From what I gather, it involves pushing on the nail bed to blanch it, but then being able to see pulsations (i.e. your pressure is between systolic and diastolic).
