The authors herein present the case of a 53-year-old female who was being treated as an outpatient for seizure disorder but was also receiving high-dose methadone therapy. She presented to the emergency department (ED) for what appeared to be a seizure and was found to have a prolonged QT interval,
BACKGROUND
Long QT syndrome (LQTS) is characterized by corrected QT interval prolongation leading to torsades de pointes and sudden cardiac death. LQTS type 2 (LQTS2) is caused by mutations in the KCNH2 gene, leading to a reduction of the rapidly activating delayed rectifier K+ current and loss of
Syncope is a common and difficult differential diagnosis for epilepsy. One possible cause for a cardiac syncope is a long QT syndrome (LQTS). LQTS with torsade de pointes tachycardia can lead to lethal ventricular fibrillation and cardiac arrest. Patients with LQTS when first diagnosed as suffering
Torsades de pointes (TdP) is a rare but hazardous ventricular dysrhythmia caused by an increase in the QT interval of the heart rhythm and is categorized into congenital or acquired types. Signs and symptoms of TdP include syncope, seizure, ventricular fibrillation, and even sudden death. According
Drug-induced QT prolongation is a potentially dangerous adverse effect of some medication combinations. When QT prolongation progresses to torsade de pointes, life-threatening or fatal outcomes may result. A 57-year-old man with a history of human immunodeficiency syndrome on abacavir, nevirapine,
Sudden unexpected death in epilepsy (SUDEP) is the most common epilepsy-related cause of death. While the precise pathophysiological mechanisms underlying SUDEP are still uncertain, impaired cardiac function including seizure-induced arrhythmias has received increased attention. In addition, the
We report here 2 cases of methadone induced Torsades de Pointes with a clinical presentation mimicking convulsive seizures in a substance abuser. These cases highlight the importance of being aware of methadone-induced Torsades de Pointes and the occasional atypical clinical presentations of this
A 50 year old woman with a previous diagnosis of epilepsy presented to the emergency department with a generalised seizure. Her admission ECG showed QT prolongation secondary to bradycardia and a subsequent seizure in the department demonstrated that these events were secondary to cerebral
METHODS
A 17-year-old female student presented in our emergency room after a seizure with motoric fits and enuresis. It was the second event of this kind within 3 weeks.
METHODS
The resting ECG on admission showed sinus bradycardia at 45 bpm and a remarkable repolarisation with notched or bifurcated
Seizures can be difficult to distinguish from other causes of transient cerebral hypoxia in the emergency department. We present a case of seizure activity in a woman in whom EKG led to a diagnosis of intermittent monomorphic and polymorphic ventricular tachycardia (torsades de pointes),
An overdose of astemizole predisposes the myocardium to ventricular dysrhythmias, including torsades de pointes. Herein we describe a case of astemizole-induced torsades de pointes ventricular tachycardia and also review previous case reports in the literature. All the patients were young, and
A case of torsade de pointes (TdP) with complete atrioventricular block and pacemaker failure that was misdiagnosed as epilepsy is presented herein. An 82-year-old female with recurrent seizure-like attacks showed epileptiform discharge during an electroencephalogram recording. A long QT interval
BACKGROUND
Alcohol withdrawal seizures and delirium tremens (DT) are serious complications of alcohol dependence. The prevalence of arrhythmias and other electrocardiographic (ECG) changes occurring in these clinical situations is not well studied.
METHODS
We performed a retrospective analysis of
