Editorial to “pseudo‐slow‐fast atrioventricular nodal reentrant tachycardia: Is the fast pathway a criminal or innocent bystander?”

The earliest atrial activation site (EAAS) was the proximal coronary sinus (CS). [...]the final diagnosis of SVT1 was slow-slow AVNRT with an upper common pathway. An additional investigation to measure the longer coupling interval of a single extra stimulus from the proximal CS region than near the His bundle site to reset SVT2 may further support that SVT2 is a slow-slow AVNRT. 2 In addition, it may have been better to test reproducibility by gradually shifting the timing of the ventricular extrastimuli to exclude the possibility that the early ventricular extrastimuli accidentally changed the retrograde conduction from the fast pathway to the slow pathway.
