Brief Summary
To study new maneuvers to differentiate AVNRT from orthodromic AVRT including VA interval variability at tachycardia induction, SA-VA base and local VA index (difference between local VA interval, measured on the coronary sinus catheter during tachycardia and entrainment, at the site of earliest atrial activity).
