Background: Atrioventricular nodal reentry tachycardia (AVNRT) is the most common paroxysmal supraventricular tachycardia. The relatively ineffective antiarrhythmic drugs and the predominant young age makes the catheter ablation the therapy of choice in many patients. This results in predominance of this arrhythmia in electrophysiological labs. The aim of the study was to analyze the gender-related differences among patients undergoing the radiofrequency catheter ablation of slow pathway entrance to the atrioventricular node. Material and methods: The study group comprised of 147 consecutive patients with diagnosed atrioventricular nodal reentry tachycardia, who underwent the radiofrequency catheter ablation (RFCA) of slow pathway. Patients have been divided into 2 groups, based on sex. Results: The overall 97.3% of effectiveness of RFCA was observed. Women were significantly younger than men (53.7+/-17.2 vs 57.7+/-9.8 years) with lower radiation dose (2383.5+/-1993.2 vs 2891.6+/-2377.1 cGyxcm2). Conclusions: Younger age of women in comparison to men during RFCA of AVNRT reflects earlier onset of symptoms in women. Gender does not affect the time of fluoroscopy, but the higher rate of inducible tachycardia after RFCA in women may suggest the existence of anatomical difficulties or the operator’s apprehensions. Sex-related difference in radiation dose that we have observed may result from the greater volume of the men’s chest.

We present a case of a 68-year-old man with a history of myocardial infarction, and CABG procedure in the past who experienced bradycardic atrial fl utter manifested by pre-syncope events and palpitations. The patient underwent a successful procedure of a catheter RF ablation with a subsequent implantation of a DDDR pacemaker. In the article, we discuss a need for specifi c treatment recommendations in case of atrial fl utter with slow ventricular response.

Przedstawiamy przypadek 68-letniego mężczyzny po przebytym zawale mięśnia serca, po operacji pomostowania tętnic wieńcowych, u którego rozpoznano trzepotanie przedsionków z wolną akcja serca manifestujące się jako stany przedomdleniowe z okresowym uczuciem kołatania serca. Chorego poddano skutecznemu zabiegowi ablacji trzepotania przedsionków, a następnie implantowano stymulator DDDR. W artykule omówiono potrzebę sformułowania określonych wytycznych postępowania w przypadku obecności trzepotania przedsionków z wolna akcją komór.
