![]() There was no significant difference in QTc increase between the groups. A prolongation of QTc appeared when standing up for both cases and controls. QTc was prolonged among long-QT syndrome children while lying down and when standing up, compared to controls. ResultsĪll children with long-QT syndrome were treated with propranolol. The QTc interval and QTc-difference by changing the body position were calculated. The ECG standing was performed immediately after the ECG in the supine position. MethodsĬhildren aged 1–18 years with long-QT syndrome ( N = 17) matched to two healthy controls ( N = 34) were included in this case-control study. In this study, we assessed the QTc interval while laying down and during active standing in children with known long-QT syndrome compared to healthy controls. Few studies have assessed QTc in relation to body posture in children. Long-QT syndrome may be presented with syncope, ventricular arrhythmias or sudden death and is vital to exclude as an underlying cause in children presented with syncope. Class Ia, Ic, and III antiarrhythmics are avoided.Syncope is a common and often benign disorder presenting at the pediatric emergency department. read more ) shortens the QT interval and may be effective especially for drug-induced torsades de pointes. If necessary, direct antiarrhythmic therapy, including antiarrhythmic. Lidocaine (a class Ib antiarrhythmic drug Class Ib antiarrhythmic drugs The need for treatment of arrhythmias depends on the symptoms and the seriousness of the arrhythmia. If this treatment is unsuccessful, a 2nd bolus is given in 5 to 10 minutes, and a magnesium infusion of 3 to 20 mg/minute may be started in patients without renal insufficiency. Patients often respond to magnesium, usually magnesium sulfate 2 g IV over 1 to 2 minutes. read more ), which can exacerbate the risk of ventricular arrhythmias, should be corrected. Electrolyte abnormalities (eg, hypokalemia Hypokalemia Hypokalemia is serum potassium concentration < 3.5 mEq/L (< 3.5 mmol/L) caused by a deficit in total body potassium stores or abnormal movement of potassium into cells. Nevertheless, early recurrence is the rule. ![]() Symptoms and Signs of Torsades de Pointes Ventricular TachycardiaĪn acute episode prolonged enough to cause hemodynamic compromise is treated with unsynchronized cardioversion Defibrillation Cardiopulmonary resuscitation (CPR) is an organized, sequential response to cardiac arrest, including Recognition of absent breathing and circulation Basic life support with chest compressions. read more, and structural heart disease (especially acute ischemia, myocarditis, and ventricular hypertrophy). read more, organophosphate poisoning Organophosphate Poisoning and Carbamate Poisoning Organophosphates and carbamates are common insecticide ingredients that inhibit cholinesterase activity, causing acute muscarinic manifestations (eg, salivation, lacrimation, urination, diarrhea. read more ), eating disorders Introduction to Eating Disorders Eating disorders involve a persistent disturbance of eating or of behavior related to eating that Alters consumption or absorption of food Significantly impairs physical health and/or psychosocial. ![]() Diagnosis is suspected clinically and confirmed by imaging (primarily. read more, traumatic brain injury Traumatic Brain Injury (TBI) Traumatic brain injury (TBI) is physical injury to brain tissue that temporarily or permanently impairs brain function.
