چکیده
A case of a 58-year-old woman with occasionally diagnosed persistent atrial fibrillation (AF) is presented. The patient for many years experienced palpitations relived by oral propranolol treatment. After electrical cardioversion of AF to sinus rhythm prolongation of the QTc interval up to 520 ms became evident. Molecular screening of LQTS-related genes revealed the presence of R231S mutation in the KCNQ1 gene.

Assessment of P-wave indices as atrial fibrillation predictors in psoriasis patients
Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...
متن کاملمعرفی یک مورد بیمار نجات یافته از مرگ ناگهانی ناشی از سندرم QT طولانی
Çongenital long-QT syndrome (LQTS) is an inherited disorder that presents with syncope, polymorphic ventricular tachycardia, torsade de pointes and sudden death. The incidence rate of LQTS is 1 to 2 per 100000 and mainly involves children and young individuals. Because of familial and genetic underling and predisposing factors for life threatening arrhythmias in patients, diagnosis and treatm...
متن کاملTorsades de Pointes associated with QT prolongation after catheter ablation of paroxysmal atrial fibrillation
A 79-year-old woman who underwent catheter ablation for paroxysmal atrial fibrillation presented with Torsades de Pointes (TdP). Aggravation of prolonged QT interval which is most likely due to neural modulation by catheter ablation, played major role in the initiation of TdP. The patient was successfully treated with isoproterenol during acute stage and discharged after stabilization without i...
متن کاملCongenital Short QT Syndrome
Long QT intervals in the ECG have long been associated with sudden cardiac death. The congenital long QT syndrome was first described in individuals with structurally normal hearts in 1957.1 Little was known about the significance of a short QT interval. In 1993, after analyzing 6693 consecutive Holter recordings Algra et al concluded that an increased risk of sudden death was present not only ...

We are presenting a case illustrating atrial fibrillation (AF) following the use of methylprednisolone in a patient with pelvic and femur fracture. A 48- year- old man with no significant past medical history, was admitted to the emergency department after injury in a car accident. He suffered a multiple bone fracture with chief complaints of pain and shortness of breath. He was transfer...

OBJECTIVES The purpose of this study was to evaluate the efficacy of various antiarrhythmic drugs at prolonging the QT interval into the normal range and preventing ventricular arrhythmias in patients with short QT syndrome. BACKGROUND Short QT syndrome is a recently described genetic disease characterized by short QT interval, high risk of sudden death, atrial fibrillation, and short refract...
