Аннотация:ABSTRACT
Radiofrequency ablation of atrioventricular nodal reentrant tachycardia is commonly
guided by slow and sharp bipolar potentials of the atrioventricular slow nodal pathway.
We optimized the morphology of the guiding potential by unipolar mapping of the slow
nodal pathway. We identified a novel unipolar dual-component atrial electrogram at the
anterior limb of the coronary sinus ostium. The first component was a positive delta-wave
type that corresponded to the isoelectric phase on a bipolar electrogram. The second
component had fast biphasic morphology and corresponded to the R wave on a bipolar
atrial electrogram. Of 104 consecutive patients with typical atrioventricular nodal
reentrant tachycardia, 51 were treated with ablation guided by the novel potential, and 53
underwent ablation using the conventional technique. There was no recurrence of
tachycardia in any of these patients. In those treated by the novel potential, there was
significantly less radiofrequency power applied and a shorter duration of application than
in patients treated by the traditional approach. The novel approach to mapping and
ablation of the slow nodal pathway in atrioventricular nodal reentrant tachycardia guided
by unipolar recording was safe and effective, and comparable to the traditional technique.
