Figure 2. Non-invasive programmed stim from the RV ICD lead with up to 3 extrastimuli following a drive train of 400ms could not induce VT in this patient with ischemic cardiomyopathy and known history of VT (Panel A). PVCs were also present and pacing from the LV lead at 600ms intermittently fusing with PVCs readily induced the clinical VT in the same patient.
