Torsades de Pointes is associated with QTc prolongation, which is the … 2020-08-11 Torsades de Pointes is associated with long QT syndrome, a condition whereby prolonged QT intervals are visible on the ECG. Long QT intervals predispose the patient to an R-on-T phenomenon, where the R wave representing ventricular depolarization occurs simultaneously to the relative refractory period at the end of repolarization (represented by the latter half of the T-wave).

The vast majority of torsades results from acquired long-QT syndrome Torsade de pointes is an uncommon and distinctive form of polymorphic ventricular tachycardia (VT) characterized by a gradual change in the amplitude and twisting of the QRS complexes around the isoelectric line (see the image below).

Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION. A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points.

Torsades can be caused by either congenital long-QT syndrome or acquired long-QT syndrome (due to electrolyte abnormalities and/or medications).

This arrhythmia may cease spontaneously or degenerate into ventricular fibrillation. Torsades de Pointes: Frequent PVCs with ‘R on T’ phenomenon trigger a run of polymorphic VT which subsequently begins to degenerate to VF. QT is difficult to see because of artefact but appears slightly prolonged (QTc ~480ms), making this likely to be TdP.
