Protective effect of acquired long QT syndrome in Takotsubo syndrome
Internal Medicine Journal, 2019AbstractBackgroundClinical variables that predict long‐term mortality and recurrence of Takotsubo syndrome (TTS) are not completely understood as the role of acquired corrected QT interval (QTc) prolongation.AimTo detect the prevalence of QTc interval prolongation in patients with TTS and to evaluate its long‐term prognostic impact.MethodsQTc intervals

Acquired long QT syndrome and torsade de pointes
PACE - Pacing and Clinical Electrophysiology, 2018AbstractSince its initial description by Jervell and Lange‐Nielsen in 1957, the congenital long QT syndrome (LQTS) has been the most investigated cardiac ion channelopathy. Although congenital LQTS continues to remain the domain of cardiologists, cardiac electrophysiologists, and specialized centers, the by far more frequent acquired drug‐induced LQTS ...

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.

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.

Post-acute management of the acquired long QT syndrome
Postgraduate Medical Journal, 2014Abstract The mechanisms underlying drug induced QT prolongation and the immediate treatment of torsade de pointes have been extensively studied but the post-acute management of the Acquired Long QT Syndrome (ALQTS) remains to be addressed.

Acquired long QT Syndrome: Case report
III SEVEN INTERNATIONAL MULTIDISCIPLINARY CONGRESS, 2023Long QT syndrome, whether genetic or acquired, is closely associated with arrhythmogenic potential and consequently with syncope or even sudden death. This case report concerns a 77-year-old female who attended the emergency department for right-sided hemiparesis, diagnosed with ischemic stroke.

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

Revue medicale suisse, 2013
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 ...

Atrioventricular block in a new born with acquired long QT syndrome
Cardiology in the Young, 2001We report a case of 2:1 atrioventricular block associated with acquired long QT syndrome. A newborn presented to our neonatal intensive care unit with intermittent bradycardia due to 2:1 atrioventricular block. Initial evaluation showed QT prolongation and significant electrolytic abnormalities.
