A 55 year-old man with a history of inferoapical myocardial infarction presented with symptomatic tolerated ventricular tachycardia (VT) and was referred for catheter ablation. A linear tridecapolar catheter (1-1-1 mm, T3, Access Point Technologies, Rogers, MN) was positioned along the region of endocardial isochronal crowding on the isochronal late activation map. Stable monomorphic VT with right bundle branch superior axis with V4 transition was induced and exhibited spontaneous variability in tachycardia cycle length (TCL; 360–415 ms). What is the mechanism of oscillation in TCL? (Figure 1)
