Three cases with supraventricular tachyarrhythmias related to oesophageal transit are reported. A 61 year old man had episodes of atrial tachycardia on each swallow of food but not liquid; this has been reported only rarely. A 55 year old man had atrial fibrillation initiated by drinking ice cold beverages; this has not been described previously although atrial tachycardia triggered by drinking...

Introduction The preferential origin of atrial tachycardia (AT) is generally associated with specific anatomical atrial structures such as crista terminalis, tricuspid annulus, mitral annulus, and pulmonary veins. There are 3 major mechanisms of focal AT: enhanced automaticity, triggered activity, and microreentry. Focal AT can be eliminated via radiofrequency ablation with fairly good long-ter...

INTRODUCTION The superior vena cava (SVC) can act as an origin of atrial fibrillation (AF). The complex structure and special conductive properties of the SVC can result in complicated atrial tachycardia (AT), atrial flutter, or AF. SYMPTOMS AND CLINICAL FINDINGS We report a case of the clinical observation of various kinds of AT and AF in 1 patient. Electrophysiological (EP) studies confirme...

BACKGROUND Catheter ablation has evolved as a possible curative treatment modality for supraventricular tachycardias (SVT) in patients with univentricular heart. However, the long-term outcome of ablation procedures is unknown. We evaluated the procedural and long-term outcome of ablative therapy of late postoperative SVT in patients with univentricular heart. METHODS AND RESULTS Patients wit...

The effect of surgical ablation of atrioventricular accessory pathways on the incidence of atrial fibrillation in patients with Wolff-Parkinson-White syndrome was examined and the results of preoperative electrophysiologic testing were studied to determine factors predictive of outcome. Among 50 consecutive surgical cases, 19 patients were identified with a past history of at least one episode ...
