However, human data regarding RVP burden and mitochondrial function is scarce. We aimed to investigate the association between the duration and percentage of RVP and mitochondrial function in the peripheral blood mononuclear cells (PBMCs). This cross\u2010sectional study enrolled individuals with a permanent pacemaker device with RVP capabilities, implanted for over 1\u2009month, and exhibiting preserved left ventricular (LV) systolic function. The assessment of mitochondrial function was conducted using PBMCs to explore its correlation with RVP burden since pacemaker implantation. The analysis included 96 patients. The majority of patients had advanced or third\u2010degree atrioventricular block, with a median RVP percentage of 84% and a median duration since implantation was 64\u2009months. Substantial RVP percentage (RVP\u2009\u2265\u200940%) was independently associated with increased cellular oxidative stress (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.015). Patients with longer RVP exposure (duration since implantation\u2009\u2265\u200960\u2009months) were independently associated with increased mitochondrial oxidative stress (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.030).
