Evaluation of the pulmonary artery potential using a 20-polar circumferential catheter and three-dimensional integrated intracardiac echocardiography.

abstract：:The inducibility of reentry was compared for four QT patterns in a heart conduction simulation model. Local (L) and gradual (G) QT prolongation models are more susceptible to reentry induction than the no (N) QT prolongation model (reentry induced episodes for N, L, and G numbered 90, 120, and 122, respectively). This...
