Pharmacogenomics and Acquired Long QT Syndrome
Pharmacogenomics, 2005During the past decade pharmaceutical companies have been faced with the withdrawal of some of their marketed drugs because of rare, yet lethal, postmarketing reports associated with ventricular arrhythmias. The implicated drugs include antiarrhythmics, but also non-cardiac drugs, such as histamine blockers, antipsychotics, and antibiotics.

Ciprofloxacin-induced acquired long QT syndrome
Heart Rhythm, 2004Quinolone antibiotics have potentially serious proarrhythmic effects. The effects on intracardiac potassium channels result in QT interval prolongation, leading to torsades de pointes. Evidence suggests fluoroquinolones cause QT-mediated proarrhythmia, and weak evidence links ciprofloxacin with QT-mediated arrhythmias.

Pediatric Emergency Care, 2014
Acquired long QT syndrome (LQTS) is a disorder of cardiac repolarization most often due to specific drugs, hypokalemia, or hypomagnesemia that may precipitate torsade de pointes and cause sudden cardiac death. Common presentations of the LQTS are palpitations, presyncope, syncope, cardiac arrest, and seizures.

Acquired Long QT Syndrome and Torsades de Pointes
, 2020Acquired long QT syndrome is an arrhythmogenic syndrome which is associated with life-threatening ventricular tachyarrhythmias termed as torsades de pointes and sudden death as the consequence of QT prolongation after exposure to secondary factors, e.g., drugs; electrolyte abnormalities including hypokalemia, hypomagnesemia, or hypocalcemia; and marked

Patients with chronic kidney disease (CKD) have a high risk of fatal arrhythmias. The extended severe corrected QT (QTc) interval is a hallmark of ventricular arrhythmias and sudden cardiac death.

The long QT syndrome may be acquired or genetically determined. The syndrome is characterized by a prolonged QT interval and is associated with an increased risk of cardiac arrhythmia such as a torsade de pointe and death. Electrolytes disorders such as hypomagnesemia and hypokaliemia and several drugs may increase the risk to develop a long QT ...

Acquired (Drug-Induced) Long QT Syndrome
2008The most common cause of acquired drug-induced long QT syndrome (ADILQTS) in clinical practice is an exposure of the heart to drugs known for their potential to prolong the QT interval. It has long been recognized that most drugs that prolong the duration of the QT interval can cause fatal tachyarrhythmias. However, it took decades to sensitize medical

Congenital and Acquired Long QT Syndrome
Cardiology in Review, 2004Congenital long QT syndrome (LQTS) is a rare but potentially lethal disease, characterized by prolongation of QT interval, recurrent syncope, and sudden death. In the pregenomic era (1959-1991), sympathetic imbalance was thought to be responsible for this disease.

Acquired long QT syndrome and elective anesthesia in children
Pediatric Anesthesia, 2006SummaryWe present the case of a child who had had a previous episode of torsades de pointes (TdP) and who was scheduled for elective surgery under general anesthesia. The pathophysiology of this condition and the anesthesia concerns are discussed. An 8‐year‐old male with a history of osteogenic sarcoma had undergone an uneventful limb salvage procedure
