However, the value of corrected PPI\u2010TCL in determining the site of the accessory pathway (AP) in ORT has not been investigated. The purpose of this study was to assess whether the corrected PPI\u2010TCL is useful in differentiating ORT using a left\u2010sided AP from a right\u2010sided AP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We studied 52 patients with ORT using a left\u2010sided AP and 13 patients with a right\u2010sided AP. The PPI was measured upon cessation of the RV pacing at a cycle length 10\u201340 ms shorter than the TCL. The corrected PPI\u2010TCL was calculated from the subtraction of the increment in AV nodal conduction time of the first PPI from the PPI\u2010TCL.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean corrected PPI\u2010TCL was 83 \u00b1 20 ms in patients with ORT using a left\u2010sided AP and 27 \u00b1 19 ms in patients with a right\u2010sided AP (P \u2264 0.001).
