title: [Spectrum of atrial arrhythmias from the right upper pulmonary vein--successful isolation of the arrhythmogenic focus by RF ablation of atriovenous breakthroughs--a case report].
abstract: We present a case of a 19-year-old patient with incessant arrhythmias originating from the right upper pulmonary vein (RUPV) presenting as frequent premature beats, automatic rhythms mimicking sinus rhythm (SR) and pulmonary vein tachycardias. Morphology of P' wave resembled sinus P wave due to relatively short distance of the ectopic focus from the sinus node. Occasionally, when discharges from the focus were relatively slow (800-500 ms) and regular it was mimicking sinus rhythm. Activation preceding P' wave during arrhythmia was recorded in RUPV as well as in superior vena cava. In this paper we discuss our approach that allowed localising the arrhythmogenic focus in the RUPV. After isolation of the RUPV sinus rhythm was restored with tachycardia at a cycle length of 320 ms continuing in the isolated vein.
