However, this increase in heart rate could also be caused by a vascular factor, such as venous entrapment. The aim of this study was to determine whether heart rate increases specifically in the case of venous entrapment during upper‐limb dynamic mobilization tasks.  \nMethods: One hundred and sixteen patients were asked to perform a provocative manoeuvre consisting of consecutive upper limb mobilizations by raising their arms to the “surrender” position (Su, 90° abduction) and then keeping their arms raised in front of the body (“prayer” position, Pra) prior to returning to the initial position (“End”) . During this manoeuvre, simultaneous venous (V‐PPG) and arterial (A‐PPG) photoplethysmography (PPG) recordings were obtained. Participants were categorized by PPG recording analysis as having bilateral venous compression only (V‐group) or having no vascular compression (C‐group) . All other responses (n = 75) were excluded. Heart rate responses in V‐group and C‐group were compared across arm positions using a linear mixed model.  \nResults: V‐group (n = 17) showed a significantly higher heart rate during the ‘Su’phase compared to the ‘Rest’ phase (+6 .9 bpm, p \u003C 0 .001) and compared to the 24 patients of the C‐group (+4 .9 bpm, p = 0 .02) .  \nConclusion: This study suggests that the cardiovascular response to dynamic provocative manoeuvres is found specifically in the presence of positional venous upper‐limb entrapment and likely results from decreased cardiac pre‐charge rather than from adrenergic nerve excitation.  \nKEYWO R DS  \nelevated arm stress test, heart rate, hemodynamics, pathophysiology, photoplethysmography, venous entrapment  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2025 The Author(s) .

The structures usually involved in the thoracic outlet region are the first rib and the anterior scalene muscle, whose local imprint mainly affects the brachial plexus and subclavian vessels (Grunebach et al., 2015). While some authors estimated only 2.5 to 4 cases per 100000 people per year in the general population (Illig & Rodriguez‐Zoppi, 2021), other studies have reported a broader incidence range, estimating between 3 and 80 cases per 1000 people (Liet al., 2021).
