Transient Long QT Development in a Patient with Takotsubo Cardiomyopathy

Journal of Cardiovascular Emergencies, 2016
QT interval prolongation on the electrocardiogram is considered a precursory sign for imminent, potentially lethal ventricular arrhythmias. Beside the inherited condition of long QT syndrome, numerous drugs, certain electrolyte disturbances and early ...

CLINICAL SIGNIFICANCE OF DRUGINDUCED INTERVALS QT AND QTC PROLONGATION

Рациональная фармакотерапия в кардиологии, 2015
Interval QT prolongation is a predictor of the life-threatening cardiac arrhythmias — polymorphic ventricular tachycardia (torsade de pointes). Long QT syndrome may be congenital or acquired.

Torsades de pointes during laparoscopic adrenalectomy of a pheochromocytoma: a case report

Journal of Medical Case Reports, 2011
Introduction Torsades de pointes is a rare but potentially lethal arrhythmia. The amount of literature available on Torsades de pointes occurring in patients with pheochromocytoma is limited, and we found no literature describing this dysrhythmia in a ...

Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]

, 2000
Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

Prolonged QT Interval in Cirrhosis: Twisting Time?

Gut and Liver, 2022
Approximately 30% to 70% of patients with cirrhosis have QT interval prolongation. In patients without cirrhosis, QT prolongation is associated with an increased risk of ventricular arrhythmias, such as torsade de pointes (TdP).
