متن کاملAtrio-Ventricular Block-Induced Torsades de Pointes: An Update
Torsades de pointes is a potentially life threatening form of rapid, polymorphic ventricular tachycardia. Literally meaning “twisting of the points”, torsades de pointes is electrocardiographically characterized by QRS axis undulations over runs of several beats, with a specific twist of the QRS complex around the isoelectric baseline. The definition also requires that an abnormal QT-prolongati...
متن کاملMethadone-induced Torsades de pointes.
Torsades de pointes is a polymorphic ventricular tachycardia that can quickly evolve into ventricular fibrillation and sudden death. This arrhythmia often occurs secondary to medication- induced cardiac repolarization dysfunction with resultant prolonged QTc interval on ECG. Numerous medications can predispose patients to this deadly tachycardia. We report a case of methadone-induced Torsades d...
متن کاملTorsades de pointes: unanswered questions.
Torsade de pointes (Tdp) is a polymorphic ventricular tachycardia (VT) in which the axis of the QRS complex changes direction after a certain number of complexes as if the complex rotated around the baseline. Tdp is usually associated with QT prolongation, and dispersion of ventricular repolarlization (DR). Experimental models of tdp are usually associated with induction of early after depolari...
متن کاملAtrioventricular block-induced Torsades de Pointes with clinical and molecular backgrounds similar to congenital long QT syndrome.
BACKGROUND Atrioventricular block (AVB) sometimes complicates QT prolongation and torsades de pointes (TdP). METHODS AND RESULTS The clinical and genetic background of 14 AVB patients (57±21 years, 13 females) who developed QT prolongation and TdP was analyzed. Electrophysiological characteristics of mutations were analyzed using heterologous expression in Chinese hamster ovary cells, togethe...
