Negative lead I P waves during anteroseptal accessory pathway orthodromic reciprocating tachycardia

Am J Cardiol. 1997 Jul 15;80(2):227-9. doi: 10.1016/s0002-9149(97)00329-9.

Abstract

Although a negative retrograde P wave in lead I during orthodromic reciprocating tachycardia is thought to indicate a left free wall accessory pathway, we describe similar negative P waves in lead I during orthodromic reciprocating tachycardia through anteroseptally situated accessory pathways.
