A patient with recurrent PSVT undergoes an electrophysiology procedure. A regular narrow QRS complex tachycardia is induced with a CL 360 ms and a 1:1 AV relationship with simultaneous atrial and ventricular activation. Figure 43.1 shows the response immediately after overdrive atrial pacing at a CL of 350 ms. Shown are the surface recordings I, II, V1, and V5 and intracardiac recordings from the high right atrium (HRA), at the His bundle region with the ablation catheter (Abl), and right ventricular apex (RV). A stimulation channel is also displayed. What is the diagnosis of the tachycardia?
