Acquired long QT Syndrome: Case report

III SEVEN INTERNATIONAL MULTIDISCIPLINARY CONGRESS, 2023
Long 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.

[Acquired long QT syndrome].

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 ...

Congenital and Acquired Long QT Syndrome

Cardiology in Review, 2004
Congenital 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.

Molecular basis of congenital and acquired long QT syndromes

Journal of Electrocardiology, 2004
In the United States, over 1,000 individuals will die suddenly each day due to a fatal ventricular arrhythmia. The vast majority of these individuals are middle-aged or elderly with coronary artery disease. Although less than 1% of these sudden cardiac deaths stem from a cardiac channelopathy like congenital long QT syndrome (LQTS), these deaths are ...

Atrioventricular block in a new born with acquired long QT syndrome

Cardiology in the Young, 2001
We 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.

Congenital and acquired long QT syndromes.

The Canadian journal of cardiology, 2003
Exploration into the underlying genetic causes of congenital long QT syndrome (LQTS) has opened the door to our understanding of repolarization disorders. Expression of LQTS mutations has led to an improved understanding of the mechanisms of arrhythmogenesis, clinical diagnostic tools and channel specific therapy.

Mechanisms of acquired long QT syndrome in patients with propionic academia

Heart Rhythm, 2016
Propionic acidemia (PROP) is a rare metabolic disorder caused by deficiency of propionyl-CoA carboxylase. PROP patients demonstrate QT prolongations associated with ventricular tachycardia and syncopes. Mechanisms responsible for this acquired long QT syndrome (acqLQTS) are unknown.The aim of the study was to investigate acute and chronic effects of ...

Acquired Long QT Syndrome Secondary to Cesium Chloride Supplement

The Journal of Alternative and Complementary Medicine, 2006
The use of complementary medication is on the rise worldwide. More often than not, the treating physicians are unaware of this and also unfamiliar with the potential benefit or toxicity of the agents. Here, we present the case of a 39-year-old woman who presented with new onset of syncope as a result of acquired long QT syndrome secondary to taking a ...

Case report, aetiology, and treatment of an acquired long-QT syndrome

Acta Clinica Belgica, 2014
Acquired long-QT syndrome is an iatrogenic disorder, usually induced by drugs, which can cause life-threatening arrhythmias. We present a case report on an acquired long-QT syndrome with an interesting confluence of circumstances, and comment on aetiology and treatment.

[Acquired long QT syndrome: a dominant problem?].

Annales de cardiologie et d'angeiologie, 2007
QT prolongation is essentially of pharmacologic origin. It is principally linked to a block of the outward potassium current Ikr, with as a consequence a prolongation of the repolarisation causing early after potentials and re-entry. The term "repolarisation reserve" expresses the variable risk of arrhythmia among individuals under the same drug ...
