additionally , the demonstration of one form of concealed entrainment , namely pacing during a ventricular tachycardia from a site which increases the tachycardia to the pacing rate but does not change the morphology of the qrs complexes , we suggest also identifies the area of slow conduction is a keystone for maintenance of the reentrant circuit , ablation of this area should be expected to provide effective therapy of the tachycardia .
