Twenty-two consecutive patients underwent esophageal stimulation and recording for the diagnosis and management of supraventricular tachycardia. In 13 of these patients, the resting electrocardiogram was normal and in nine it showed pre-excitation. Of the 13 patients with a normal resting electrocardiogram, supraventricular tachycardia was initiated in all. Seven patients had a ventricular-to-a...

Tetralogy of Fallot (TOF) is a cyanotic congenital heart disease which, without corrective surgery, has a poor prognosis. These patients have an increased incidence of arrhythmias both supraventricular and ventricular post surgical correction. The supraventricular arrhythmias are usually related to the scar tissue at the surgical repair site. We present a case of a young male patient status pos...

INTRODUCTION Standard electrophysiologic techniques generally allow discrimination among mechanisms of paroxysmal supraventricular tachycardia. The purpose of this study was to determine whether the response of paroxysmal supraventricular tachycardia to atrial and ventricular overdrive pacing can help determine the tachycardia mechanism. METHODS AND RESULTS Fifty-three patients with paroxysma...

Supraventricular arrhythmias are relatively common, often persistent, and rarely life-threatening cardiac rhythm disturbances that arise from the sinus node, atrial tissue, or junctional sites between the atria and ventricles. The term "supraventricular arrhythmia" most often is used to refer to supraventricular tachycardias and atrial flutter. The term "supraventricular tachycardia" commonly r...

OBJECTIVE To review the diagnosis, treatment, and outcome of fetal atrial flutter compared with supraventricular tachycardia. DESIGN Retrospective review of published reports: 11 papers about fetal tachyarrhythmia published between 1991 and 2002 were selected for review. MAIN OUTCOME MEASURES All selected studies were analysed for the type of arrhythmia, degree of atrioventricular block in ...

Five babies who presented with supraventricular tachycardia were treated with verapamil intravenously. All developed severe hypotension and two died. Verapamil should not be used in the initial management of supraventricular tachycardia in neonates.

introduction: recent studies have shown acute cardioprotective effects of cyclosporine. the aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (avnrt) by using extracellular field potential recordings of isolated atrioventricular-node (av-node) of rabbit. methods: this study was performed on isolated double-perfus...

Hydrops fetalis is defined by the accumulation of fluids in serous membranes (pleurisy, ascites, pericarditis...), it a rare condition; its etiologies are divided into immunological and non-immunological. Supraventricular tachycardia remains known cause, non-immunological, but difficult to manage.
 In this article we report case newborn with hydrops secondary supraventricular tachycardia, ...
