BACKGROUND Intravenous (IV) amiodarone has proven efficacy in adults. However, its use in children is based on limited retrospective data. METHODS AND RESULTS A double-blind, randomized, multicenter, dose-response study of the safety and efficacy of IV amiodarone was conducted in 61 children (30 days to 14.9 years; median, 1.6 years). Children with incessant tachyarrhythmias (supraventricular...

BACKGROUND The aim of this study was to investigate the use of prophylactic magnesium sulphate and amiodarone in treating arrhythmias that may occur following coronary bypass grafting operations. METHODS The study population consisted of 192 consecutive patients who were undergoing coronary artery bypass grafting (CABG). Sixty-four patients were given 3 g of magnesium sulphate (MgSO4) [20 ml ...

OBJECTIVE The aim of this study was to examine the prognostic significance of ventricular arrhythmia on the ambulatory electrocardiogram (ECG) after repair of tetralogy of Fallot. BACKGROUND Ventricular arrhythmia is common after repair of tetralogy of Fallot and has been proposed as the basis for late sudden death. The prognostic significance of ventricular arrhythmia on ambulatory ECG and t...

In order to assess the additional information obtained from 24 hours compared to 12 hours of ambulatory ECG (electrocardiogram) recording, we analyzed 72 ambulatory ECG monitoring tapes in which arrhythmias were present. In all cases the second 12 hours included the entire period of sleep. Only 38 of 233 (16 percent) episodes of arrhythmias, frequent premature ventricular contractions (PVC's), ...

OBJECTIVE The aim of the present study was to examine the relationship between serious arrhythmias in patients with psychotropic drug overdose and electrocardiography (ECG) findings that have been suggested previously to predict this complication. METHODS Thirty-nine patients with serious arrhythmias (ventricular tachycardia, supraventricular tachycardia or cardiac arrest) after tricyclic ant...

OBJECTIVES The goal of this study was to establish the role of ventricular filling on the 1b phase of ischemia-induced arrhythmias. BACKGROUND Ischemia-induced ventricular arrhythmias occur in two phases. The mechanism of the initiation of delayed (1b) arrhythmias is unknown. The 1b arrhythmias (15 to 60 min of ischemia) are abundant in in situ hearts but scarce in isolated perfused hearts (w...

Introduction. Atrial fibrillation is the most common supraventricular arrhythmia which also a frequent cause of calls by Emergency Medical Services Teams. The purpose work was presentation conduct Rescue Teams in about patients with atrial fibrillation. Research methodology. study included an 86-year-old woman who called Team due to increasing weakness accompanied chest pain and dyspnoea. At pa...

Amiodarone is an antiarrhythmic agent unrelated to other drugs in current use. It has been little used in Britain, and no formal clinical trials have been possible because the drug has not been licensed by the Committee on Safety of Medicines. Nevertheless it has unique properties which can be valuable in the treatment of a wide spectrum of arrhythmias, particularly supraventricular tachycardia...
