The elevation of forearm arterial blood pressureduring Riva-Rocci-Korotkoff measurements.
To investigate why the forearm pressure rises above the systemic blood pressure upon the release of occluding cuff pressure during Riva-Rocci-Korotkoff blood pressure measurements and whether this overshoot could, as has been suggested, be used to predict the accuracy of Riva-Rocci-Korotkoff measurements in a certain patient. DESIGN AND ⋯ These findings are consistent with the hypothesis that the diastolic blood pressure overshoot results from increased filling of the forearm vasculature during Riva-Rocci-Korotkoff measurements. The systolic blood pressure overshoot probably results from pulse wave amplification in the partially occluded artery underneath the upper arm cuff. The overshoot phenomenon was not related to Riva-Rocci-Korotkoff errors.
