چکیده

Copyright © 2008 Massachusetts Medical Society. After the sudden death of a 13-year-old girl while she was playing basketball, her family comes to the clinic for medical evaluation (Fig. 1). Her parents’ resting electrocardiograms (ECGs) are normal, but her 9-year-old sister’s ECG shows an abnormally long QT interval. There is a history of recurrent syncope in female relatives of the maternal grandmother, but there is no family history of other sudden deaths, the sudden infant death syndrome, drowning, or death from a motor vehicle accident. How should these family members be further evaluated and treated?

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,...

KCNE1 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...

Lack 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...

Torsades 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...

گزارش یک مورد سندرم ژرول- لانژنلسون

Long QT syndrome, which is defined by corrected QT interval longer than 0.45 seconds in men and o. 47 sec in women , could be divided into idiopathic (congenital ) and acquired forms. The idiopathic form is a familial disorder that can be associated with sensorineural deafness (Jervell and Lange- Neelson syndrome), which is transmitted with an autosomal recessive pattern. Although this syndrome...

Background and purpose: Long QT syndrome is a heart arrhythmia identified by prolongation of the QT interval which is a cause of sudden cardiac death in young individuals. In most cases, abnormalities in heart repolarization are reasons of prolongation of action potential and arrhythmia. The activity of ion channels is sensitive to ATP level, therefore, mitochondrial disorders are considered...
