A case of long QT syndrome: challenges on a bumpy road
نویسندگان
چکیده
Beta-agonist treatment during pregnancy may unmask the diagnosis of long QT syndrome. The QT prolongation can result in functional AV block. A history of seizure and/or sudden death in a family member should raise suspicion of ventricular tachycardia. More than one mutation may coexist. Refusal of beta-blocker therapy complicates risk stratification.

The relationship between Tonic-Clonic sizures in children and increased time of ventricular repolarization
Background: Long QT syndrome (LQTS) is a disorder in which electrical cardiac ventricular repolarization is impaired. It results in an increased risk of an irregular heartbeat which can result in palpitations, fainting, drowning, or sudden death. Long QT Syndrome may present as tonic-clonic seizure or a seizure-like disorder. By taking a superficial electrocardiogram (ECG) and proper diagnosis,...
متن کاملTorsades de pointes: Should ECG be taken from all patients before surgery? A case report
Torsades de pointes is a rare but potentially lethal arrhythmia which mainly occurs in the setting of a prolonged QT interval. ECG is a reliable tool to detect such abnormalities, routinely taken from all patients over 40 who undergo surgery. We describe the case of a 35-year-old woman with torsades de points arrhythmia after hysterectomy surgery. Most likely, our patients had long QT syndro...
متن کاملKCNE1 and KCNE2 variants in Patients with Long QT Syndrome
Introduction: Long QT syndrome (LQTS) is a type of ventricular arrhythmia characterized by prolonged QT intervals on electrocardiogram or delay in ventricular repolarization and it can lead to syncope, seizure and sudden cardiac death. Here, KCNE1 and KCNE2 variants are studied among Iranian affected families with this syndrome. Materials and Methods: Fifty patients referring to Rajaei Cardiov...
متن کاملLack of association between coding region of KCNE2 gene and the congenital long QT syndrome in an Iranian population
Introduction: Congenital long QT syndrome (LQTS) is a cardiac disorder characterized by QT interval prolongation at basal ECG. Different LQTS genes encode ion channel subunits or proteins involved in regulating cardiac ionic currents. Long QT syndrome type 6 (LQT6) is caused by mutation in the KCNE2 gene. Our research aimed to analyze genetic variants of KCNE2 gene causing the disease in Irania...
متن کاملIdentification of a Novel KCNQ1 Frameshift Mutation and Review of the Literature among Iranian Long QT Families
Background: Long QT syndrome (LQTS) is characterized by the prolongation of QT interval, which results in syncope and sudden cardiac death in young people. KCNQ1 is the most common gene responsible for this syndrome. Methods: Molecular investigation was performed by DNA Sanger sequencing in Iranian families with a history of syncope. In silico examinations were performed for predicting the path...
