Acquired long QT syndrome in chronic kidney disease patients [PDF]
Renal Failure, 2020 Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in chronic kidney disease (CKD) patients. QT interval prolongation is a congenital or acquired condition that is associated with an increased risk of torsade de pointes (TdP ...

The anti-aging factor Klotho protects against acquired long QT syndrome induced by uremia and promoted by fibroblast growth factor 23 [PDF]
BMC Medicine, 2022 Background Chronic kidney disease (CKD) is associated with increased propensity for arrhythmias. In this context, ventricular repolarization alterations have been shown to predispose to fatal arrhythmias and sudden cardiac death.

Mechanisms, Risk Factors, and Management of Acquired Long QT Syndrome: A Comprehensive Review [PDF]
The Scientific World Journal, 2012 Long QT syndrome is characterized by prolongation of the corrected QT (QTc) interval on the surface electrocardiogram and is associated with precipitation of torsade de pointes (TdP), a polymorphic ventricular tachycardia that may cause sudden death ...

Acquired Long QT Syndrome and Electrophysiology of Torsade de Pointes [PDF]
Arrhythmia & Electrophysiology Review, 2019 Congenital long QT syndrome (LQTS) has been the most investigated cardiac ion channelopathy. Although congenital LQTS remains the domain of cardiologists, cardiac electrophysiologists and specialised centres, the much more frequently acquired LQTS is the

In Vitro and In Silico Risk Assessment in Acquired Long QT Syndrome: The Devil Is in the Details [PDF]
Frontiers in Physiology, 2017 Acquired long QT syndrome, mostly as a result of drug block of the Kv11. 1 potassium channel in the heart, is characterized by delayed cardiac myocyte repolarization, prolongation of the T interval on the ECG, syncope and sudden cardiac death due to the ...

The diagnostic role of T wave morphology biomarkers in congenital and acquired long QT syndrome: A systematic review. [PDF]
Ann Noninvasive Electrocardiol, 2023 QTc prolongation is key in diagnosing long QT syndrome (LQTS), however 25%–50% with congenital LQTS (cLQTS) demonstrate a normal resting QTc. T wave morphology (TWM) can distinguish cLQTS subtypes but its role in acquired LQTS (aLQTS) is unclear.

Vomiting, electrolyte disturbance, and medications; the perfect storm for acquired long QT syndrome and cardiac arrest: a case report [PDF]
Journal of Medical Case Reports, 2022 Background Acquired long QT syndrome is an important and preventable cause of cardiac arrest. Certain medications and electrolyte disturbance are common contributors, and often coexist. In this case, we report five contributors to cardiac arrest.

Acquired Long QT Syndrome: Ventricular Fibrillation in an Otherwise Healthy Young Female. [PDF]
Cureus, 2023 Long QT syndrome (LQTS) occurs when there is an abnormality of myocardial repolarization characterized specifically by a prolonged QT interval on an electrocardiogram (ECG). This can be particularly dangerous as it is associated with an increased risk of

Acquired Long QT Syndrome after Acute Myocardial Infarction: A Rare but Potentially Fatal Entity. [PDF]
Tex Heart Inst J, 2020 Acquired long QT syndrome is typically caused by medications, electrolyte disturbances, bradycardia, or catastrophic central nervous system events. We report a case of myocardial infarction-related acquired long QT syndrome in a 58-year-old woman that ...
