WebbP waves vary. In most cases of AV node reentry, retrograde P waves are in the terminal portion of the QRS complex (often producing a pseudo-R ′ deflection in lead V1); about one third occur just after the QRS complex, and very few occur before. P waves always follow the QRS complex in orthodromic reciprocating tachycardia of WPW syndrome.
