Info Torsades de pointes (TdP) is a form of polymorphic VT that occurs in the setting of acquired or congenital QT interval prolongation and typically has a rate between 160 and 250 beats per minute . In the specific case of TdP, these variations take the form of a progressive, sinusoidal, and cyclic alteration of the QRS axis ( waveform 2A-B ). 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). 2020-05-25 Azole antifungal drugs (fluconazole and voriconazole) have been associated with prolongation of QT interval and cause torsade de pointes through inhibition of cardiac human ether receptor a go-go 2017-01-06 2001-03-01 2003-11-01 Background.
