A 54-year-old woman with history of septal atrial mixoma surgically treated and drug-refractory supraventricular tachyarrhythmia underwent catheter ablation of macro-reentry areas near the pericardial patch placed to repair an interatrial defect. The use of ablative therapy has been successful to cure this arrhythmia.

A neonatal patient with Wolff-Parkinson-White type A and supraventricular tachycardia is described. Demonstration of the mechanism of the tachycardia and its termination were achieved using intracardiac electrography and cardiac pacing. Quantitative left ventricular angiography and echocardiography showed impaired left ventricular function following the arrhythmia. Serial echocardiograms demons...

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...

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 ...

A case of bidirectional tachycardia is presented in a patient with cardiomyopathy, pulmonary emboli, and digitalis toxicity. The arrhythmia has usually been considered ventricular in origin. A supraventricular origin has also been suggested. Simultaneous recordings of standard electrocardiographic leads and His bundle potentials demonstrated that the abnormal rhythm originated in the left ventr...

• It was reported recently that cardiac arrhythmia induced in cyclopropane anesthetized dogs by infusion of epinephrine could be converted to normal sinus rhythm by vagal stimulation. The termination of multifocal ventricular tachycardia is interesting because it is not readily apparent how vagal influence, presumably limited to the A-V node or upper bundle of His, alters arrhythmia predominant...
