Abstract

Objective: The difference of the conduction velocity (CV) around the tricuspid valve annulus between the counter-clockwise (CCW) atrial flutter and the clockwise (CW) atrial flutter has not been well clarified. This study was undertaken to evaluate the CV and the conducting area (CA) per millisecond around the tricuspid valve annulus using the electroanatomical mapping. Methods: The electroanatomical mapping was performed during the tachycardia for 30 consecutive patients (mean age: 61±16 years) with isthmusdependent atrial flutter (CCW, 25; CW, 5). We measured the CV and the CA of five divided areas of the right atrium, that is, upper septum (US), lower septum (LS), isthmus (I), upper lateral wall (UL) and lower lateral wall (LL) using the novel measurement method in the isochronal map. Statistical differences of these data between the two groups were assessed by the Student’s t-test and one-way analysis of variance methods. Results: In total, the CV of the LS was significantly slower than other areas (m/sec: US, 0.57±0.18; LS, 0.43±0.18; UL, 0.60±0.26; LL, 0.53±0.20; I, 0.50±0.17; p

Özet

Amaç: Tipik (CCW) ve ters tipik (CW) atriyal flatterların triküspit kapak anülüsü etrafındaki ileti hızlarının farkı hala tam olarak aydınlatılmamıştır. Bu çalışma, triküspit kapak anülüsü etrafındaki ileti hızı (CV) ve iletim alanının (CA) (msn) elektroanatomik haritalama ile değerlendirmeyi amaçlamıştır. Yöntemler: İstmus bağımlı atriyal flatteri olan (CCW 25; CW 5) ardışık 30 hastada (ortalama yaş 61±16), taşikardi sırasında elektoanatomik haritalama uygulandı. CV ve CA ölçümlerini, üst septum (US), alt septum (LS), istmus (I), üst lateral duvar (UL) ve alt lateral duvar (LL) olmak üzere sağ atriyumun beş bölgesinde isokronal haritada yeni ölçüm metotları ile yaptık. Bulgular: Toplamda LS’nin CV’si diğer bölgelere kıyasla belirgin derecede yavaş idi (m/sec: US, 0.57±0.18; LS, 0.43±0.18; UL, 0.60±0.26; LL, 0.53±0.20; I, 0.50±0.17; p
