WebApr 1, 2008 · Long QT syndrome (LQTS) is caused by malfunction of cardiac ion channels impairing ventricular repolarization. 1 This predisposes to the development of the polymorphic ventricular tachycardia torsade de pointes (‘twisting of the points’) (Fig. 1).This may either revert spontaneously back to sinus rhythm causing syncope or degenerate to … WebMar 18, 2024 · This retrospective study evaluated 190 patients with polymorphic ventricular tachycardia (VT). The QT of patients with pseudo–torsade de pointes (TdP) was (by definition) longer than that of patients with polymorphic VT and a normal QT interval (QTc 491.4 ± 25.2 ms vs 447.3 ± 55.6 ms; P < .001).
