Electrophysiology study (EPS) and catheter ablation (CA) in children and adolescents carries a potentially harmful effect of radiation exposure when performed with the use of fluoroscopy. Our aim was to evaluate the feasibility, safety and effectiveness of fluoroless EPS and CA of various supra-ventricular tachycardias (SVTs) with the use of the 3D mapping system and intracardiac echocardiography (ICE). Forty-three consecutive children and adolescents (age 13 ± 3 years) underwent fluoroless EPS and CA for various supra-ventricular tachycardias...

Caffeine is arguably the most widely used stimulant drug in the world. Here we describe a suicide attempt involving caffeine overdose whereby the patient's severe intoxication was successfully treated with the prompt infusion of Intralipid. A 19-year-old man was found in an agitated state at home by the volunteer emergency team about 1 h after the intentional ingestion of 40 g of caffeine (tablets). His consciousness decreased rapidly, followed quickly by seizures, and electrocardiographic monitoring showed ventricular fibrillation...

OBJECTIVE: Loperamide, a non-prescription anti-diarrheal agent, is a peripheral mu-opioid receptor agonist that is excluded from the blood-brain barrier by p-glycoprotein at therapeutic doses. Overdoses of loperamide penetrate the central nervous system (CNS), leading to abuse. We report cardiac conduction abnormalities and dysrhythmias after ingestion of a recreational supra-therapeutic dose of loperamide confirmed with an elevated blood loperamide concentration. CASE DETAILS: A 48-year-old woman with a history of alcohol and benzodiazepine abuse presented to the emergency department (ED) with somnolence, weakness and slurred speech...

Cardiac arrhythmias, with, on top of the list, atrial fibrillation, are frequent conditions and any physician might have to get involved at any stage of patient care (from diagnosis to treatment), without always having the opportunity to immediately refer to the cardiologist. The aim of this review is to present a summary of pathophysiology, clinical and electrocardiographic presentations, as well as diagnostic and therapeutic strategies for the main cardiac arrhythmias. Supra-ventricular tachycardias (atrial fibrillation and flutter, atrioventricular reciprocating tachycardias) and ventricular tachycardias will be consecutively presented and discussed...

RATIONALE: Flecainide, a class 1c antiarrhythmic, has emerged as an effective therapy in preventing arrhythmias in patients with catecholaminergic polymorphic ventricular tachycardia (CPVT) refractory to β-adrenergic receptor blockade. It has been proposed that the clinical efficacy of flecainide in CPVT is because of the combined actions of direct blockade of ryanodine receptors (RyR2) and Na(+) channel inhibition. However, there is presently no direct evidence to support the notion that flecainide blocks RyR2 Ca(2+) flux in the physiologically relevant (luminal-to-cytoplasmic) direction...

BACKGROUND: Paroxysmal supraventricular tachycardia (PSVT) has always been a diagnostic and therapeutic challenge for the cardiologists. There are many modalities to treat the problem. Of the available pharmacological treatment, the role of verapamil and adenosine is under debate. This study was carried out to detect and compare the efficacy of both drugs. The objective of this study was to compare the efficacy of intravenous adenosine and verapamil in termination of PSVT. METHODS: This experimental study was carried out in the Emergency department of Chauhdry Pervaiz Elahi Institute of Cardiology, Multan from to August 2008 to February 2010...

Left Atrial Thrombus is uncommon in neonates. We present a neonate who had Paroxysmal Supraventricular Tachycardia (PSVT), whose echocardiography revealed a large left atrial thrombus which resolved later with treatment. Supra Ventricular Tachycardia (SVT) is not an uncommon event in infants with an incidence of 1:2500.

Two young patients with documented episodes of symptomatic paroxysmal atrial fibrillation have been referred for pulmonary vein isolation. Both patients had a history of concomitant regular tachycardia. in both cases pulmonaryvein isolation has not been performed but in each patient a supraventricular tachycardia (right focal atrial tachycardia/atrioventricular reentry tachycardia) could be induced and ablated instead. Concomitant supraventricular tachycardia acting as a trigger arrhythmia is frequent in young patients with atrial fibrillation without underlying cardiacdisease...

BACKGROUND: Some outflow tract ventricular tachycardias (VTs) are known to be successfully ablated from the aortic cusp (AC). However, radiofrequency catheter ablation (RFCA) at the AC for the treatment of supraventricular tachyarrhythmia (SVT) has limited experience. METHODS: We performed RFCA at the AC in 19 patients (male 64.7%, 46.9 ± 21.9 years old) with mid- to anteroseptal SVTs (12 atrial tachycardias [AT], 7 atrioventricular reciprocating tachycardia [AVRT]), and analyzed the prevalence, electrophysiologic findings, clinical outcome, and compilation risk...

BACKGROUND: The prevalence and nature of arrhythmias in horses following general anaesthesia and surgery is poorly documented. It has been proposed that horses undergoing emergency surgery for gastrointestinal disorders may be at particular risk of developing arrhythmias. Our primary objective was to determine the prevalence and nature of arrhythmias in horses following anaesthesia in a clinical setting and to establish if there was a difference in the prevalence of arrhythmias between horses with and without gastrointestinal disease undergoing surgery...

We report a case of fibroid uterus with Wolff-Parkinson-White (WPW) syndrome in a 48-year-old female, posted for elective hysterectomy. Patient gave history of short recurrent episodes of palpitation and electrocardiograph confirmed the diagnosis of WPW syndrome. The anaesthetic management of these patients is challenging as they are known to develop life threatening tachyarrhythmia like paroxysmal supra-ventricular tachycardia (PSVT) and atrial fibrillation (AF). Epidural anaesthesia is preferred compared to general anaesthesia to avoid polypharmacy, noxious stimuli of laryngoscopy and intubation...

In this paper we summarize present trends and controversies in the use of beta-blockers in cardiovascular diseases. Beta-blockers are catecolamine competitive inhibitors and act through alpha and beta adrenergic receptors blockade. Different agents have a dose-dependent affinity for different beta adrenergic receptors (beta 1, beta 2, beta 3) which is less with higher doses. The most important therapeutic effects of beta-blockers are on cardiovascular system, where they act as negative chronotropic and inotropic agents, lowering cardiac work and improving oxygen demand /supply ratio...
