Fever-Induced QTc Prolongation and Ventricular Fibrillation in a Healthy Young Man
نویسندگان
چکیده
Long QT syndrome is associated with lethal tachyarrhythmia that can lead to syncope, seizure, and sudden death. Congenital long QT syndrome is a genetic disorder, characterized by delayed cardiac repolarization and prolongation of the QT interval on the electrocardiogram (ECG). Type 2 congenital long QT is linked to mutations in the human ether a go-go-related gene (HERG). There are environmental triggers of adverse cardiac events such as emotional and acoustic stimuli, but fever can also be a potential trigger of life-threatening arrhythmias in long QT syndrome type 2 patients. Herein, we report a healthy young man who experienced fever-induced polymorphic ventricular tachycardia and QT interval prolongation.

گزارش موردی نادر از دو شاخه شدن موج T در زمینه طولانی شدن قطعه QT ناشی از سندرم حاد کرونری
Introduction: Bifid T waves are seen in healthy young children and alcoholic adults. They also occur in certain pathological conditions, including organic heart diseases, and the central nervous system disorder. Myocardial ischemia can affect T wave morphology in a variety of ways one of which is t wave change as bifid t wave observed in QTc prolongation forms oc-curring in acute coronary event...
متن کاملFever-induced QTc prolongation and ventricular arrhythmias in individuals with type 2 congenital long QT syndrome.
Type 2 congenital long QT syndrome (LQT-2) is linked to mutations in the human ether a-go-go-related gene (HERG) and is characterized by rate-corrected QT interval (QTc) prolongation, ventricular arrhythmias, syncope, and sudden death. Recognized triggers of these cardiac events include emotional and acoustic stimuli. Here we investigated the repeated occurrence of fever-induced polymorphic ven...
متن کاملWhen Prescribing Pain Medications, Think About Qtc Index
The QT interval in the electrocardiogram is the expression of ventricular repolarisation, it is variable in the general population and highly dependent upon heart frequency; therefore, in clinical practice, the QTc index is used, to correct for heart frequency through the well-known Bazzett’s correction formula (QTc=QT/ RR0.5) for heart frequencies below 90 bpm. The QTc index is considered norm...
متن کاملCardiac arrest in a young woman with the long QT syndrome and concomitant astemizole ingestion.
Ventricular fibrillation developed in a 19 year old woman taking the antihistamine astemizole. She was successfully resuscitated. QTc prolongation was found and persisted despite withdrawal of the drug. Aggravation of congenital long QTc syndrome by astemizole is postulated. More caution should be exercised with the use of this drug.
متن کاملQuinidine-Induced QTc Interval Prolongation and Gender Differences in Healthy Korean Subjects
Background and Objectives: Drug-induced electrocardiographic QT interval prolongation is associated with the occurrence of a potentially lethal form of polymorphic ventricular tachycardia, termed ‘torsades de pointes’ (TdP). Women are at greater risk for the development of drug-induced TdP. To determine whether this may be the result of gender-specific differences in the effect of quinidine on ...
