Phase 2 Early Afterdepolarization as a Trigger of Polymorphic Ventricular Tachycardia in Acquired Long-QT Syndrome

Background —This study examined the role of phase 2 early afterdepolarization (EAD) in producing a trigger to initiate torsade de pointes (TdP) with QT prolongation induced by dl -sotalol and azimilide. The contribution of transmural dispersion of repolarization (TDR) to transmural propagation of EA... View More
