Abstract
We thank Dr. Bhargava for his interest in our case.1 We agree that the findings in Figure 1 described by Dr. Bhargava, including S-A – VA interval >85 ms and postpacing interval – tachycardia cycle length (PPI – TCL) >115 ms are highly suggestive of atrioventricular nodal reentrant tachycardia and make orthodromic atrioventricular reentrant tachycardia (AVRT) using a septal accessory pathway unlikely.2 However, it also is true that delayed atrial activation induced by a His-synchronous ventricular extrastimulus is thought to rule in orthodromic reentrant tachycardia using a decremental accessory pathway.
