After ensuring adequate hydration, baseline RA pressures were measured as the height of \u2018a\u2019 and \u2018v\u2019 waves. The patients were asked to take deep breaths, and the measurements were taken in both inspiration and expiration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of the 16 participants, 14(87.5%) showed a normal fall in the height of \u2018a\u2019 and \u2018v\u2019 waves with inspiration, 1(6.25%) showed no change and 1(6.25%) showed a rise in height at baseline, p &lt;0.01. During induced AVNRT, the \u2018a\u2019 and \u2018v\u2019 wave heights increased in 8(50%), remained same in 6(37.5%) and showed a normal fall in 2(12.5%), p\u2009=\u20090.07 for \u2018a\u2019 waves and p\u2009=\u20090.09 for \u2018v\u2019 waves. When the magnitude and direction of change in \u2018a\u2019 and \u2018v\u2019 wave height at baseline was compared with AVNRT, it showed a significant difference with 13(81.25%) participants demonstrating positive Pseudo-Kussmaul's sign, p &lt;0.01. Mean age was numerically higher in those with a more considerable inspiratory rise in RA pressures but was not statistically significant, \u03c7\n                      <jats:sup>2<\/jats:sup>\n                      (2)\u2009=\u20093.1, p\u2009=\u20090.21.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Pseudo-Kussmaul's sign does occur in a substantial number of patients during AVNRT.
