Spuriously high BP is seen in all except

The auscultatory gap may give a falsely low recording of systolic BP, not spuriously high BP. In older patients with wide pulse pressure and in some hypeensive patients, the korotkoff sounds may become inaudible between SBP and DBP, reappear as cuff deflation continues, this is known as auscultatory gap. Small cuff size, obesity, and thick calcified aeries can give falsely high BP as in these condition, vessels are difficult to compress and higher cuff pressure is required to compress them.
