The report describes the case of electrophysiological study and catheter ablation of seven types of supraventricular tachycardia in one patient. During radiofrequency ablation for WPW-syndrome three functionated discrete retrograde conductive accessory atrioventricular pathways were documented and were successfully ablated. Further incessant activity of two ectopic atrial focuses was revealed. First localized in upper part of crista terminalis and another – in left superior pulmonary vein ostium. Five months after patient had a recurrence of supraventricular tachycardia. EPI-study demonstrated evidence for retrograde ventriculoatrial dissociation with induction of atypical fast/slow and typical slow/fast atrioventricular nodal reentry tachycardia, wich were successfully ablated. With further observation, rhythm disturbances did not recur.
