OBJECTIVE To study various types of supraventricular arrhythmias in patients with Brugada Syndrome. METHODS Forty six patients with ECG of spontaneous type Brugada and with ventricular and/or supraventricular tachyarrhythmia, without structural heart diseases which were excluded by echocardiography, underwent 24 h-Holter recording, electrophysiological study and/or radiofrequency ablation. ...

A 48-year-old man with severe pectus excavatum presented with incapacitating supraventricular tachycardia, paroxysmal in nature and invariably provoked by exercise. During mild supine leg exercise on a bicycle ergometer an abnormal increase in right heart pressures, particularly in the right atrium, was observed, followed immediately by supraventricular tachycardia. The latter was also shown du...

We present here a 45-year-old male with no past medical problem who presented with palpitations. He was found to have supraventricular tachycardia intractable to medical therapy. Later his rhythm converted to junctional tachycardia. Further workup revealed hemochromatosis to be primary etiology causing the arrhythmia. The low index of suspicion for additional workup is key to diagnosis and succ...

PURPOSE Flecainide is a class 1C antiarrhythmic drug especially used for the management of supraventricular arrhythmia. Flecainide also has a recognized proarrhythmic effect in patients treated for ventricular tachycardia. It is used to treat a variety of cardiac arrhythmias including paroxysmal atrial fibrillation, paroxysmal supraventricular tachycardia and ventricular tachycardia. Flecainide...

A total of 13 (4.5%) of 290 patients with aborted sudden death had either documented (7; 54%) or strong presumptive evidence of supraventricular tachycardia that deteriorated into ventricular fibrillation. Six (46%) of the 13 had an accessory conduction pathway and either atrial fibrillation (5 patients) or paroxysmal atrioventricular (AV) reentrant tachycardia (1 patient) that deteriorated int...

In six successive patients, none of whom had the Wolf-Parkinson-White syndrome, recurrent episodes of paroxysmal supraventricular tachycardia (SVT) were analyzed to determine the mechanism by which this arrhythmia is initiated and sustained. In each patient, simultaneous intracavitary atrial electrograms and surface electrocardiograms were recorded during the onset of numerous spontaneous episo...
