[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]. / Zespól uporczywych arytmii z zyly plucnej górnej prawej w postaci licznych pobudzen przedwczesnych, rytmów imitujacych rytm zatokowy, patologicznej bradykardii oraz napadów czestoskurczu--rola ablacji wybiórczej.

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.

[Focus from superior vena cava and atypical atrioventricular nodal reentrant tachycardia in patient with paroxysmal atrial fibrillation--selective RF ablation]. / Wybiórcza ablacja migotania przedsionków u pacjentki z ogniskiem w zyle glównej górnej i atypowa postacia AVNRT.

We describe a case of a 34-year-old woman with atrial fibrillation induced by focal frequent tachycardias from superior vena cava and atypical atrioventricular nodal reentrant tachycardia. Selective isolation of SVC and slow pathway RF ablation cured all types of atrial arrhythmias. The slow pathway was localised in the postero-septal mitral anulus and ablated from the left atrium.

[Pseudoaneurysm of arteriovenous fistula for haemodialysis]. / Tetniak rzekomy przetoki tetniczo-zylnej do hemodializy--opis dwóch przypadków.

On the basis of two cases of haemodialysed patients we present the usefulness of spiral computed tomography in the diagnosis of pseudoaneurysm as a complication of arteriovenous fistula for haemodialysis.
