(A) Schematic diagrams depicting the V‐A‐A‐V and V‐A‐V responses after ventricular overdrive pacing (VOP), according to the mechanisms of tachycardia, along with intracardiac electrograms in (B) AT, (C) slow‐slow AVNRT, and (D) fast‐slow AVNRT. A, atrium; AP, accessory pathway; AVN, atrioventricular node; AVNRT; atrioventricular nodal reentrant tachycardia; AT, atrial tachycardia; CS, coronary sinus; d, distal; FP, fast pathway; H, His; HB, His bundle; HRA, high right atrium; ORT, orthodromic reciprocating tachycardia; p, proximal; RVA, right ventricular apex; S, stimulus; SP, slow pathway; VOP, ventricular overdrive pacing; V, ventricle.
