Abstract
We present a case of a 17-year-old patient in whom recurrent bradycardia and syncope episodes were present. During the pathological bradycardia incessant runs of irregular tachycardia from the region of atrial extension of AV node were observed. The bradycardia runs were due to advanced functional AV nodal block. The patient was qualified for pacemaker implantation and antiarrhythmic treatment by his GP. Successful ablation of atrial tachycardia revealed that SA and AV node properties were in the normal range; therefore no pacemaker implantation was needed.
