A 44-year-old man with a long history of a narrow complex tachycardia and prior left lateral accessory pathway(LL-AP)ablation was brought to the electrophysiology laboratory for a redo supraventricular tachycardia(SVT)ablation procedure.Catheters were positioned within the coronary sinus(CS)and right ventricular apex(RVa).The case was performed with the guidance of a 3D mapping system A long RP tachycardia with a cycle length of 320 ms was easily
