摘要
为探讨房室结改良术成功后不同电生理终点对复发率的影响，观察了８０例房室结改良术患者复发情况。其中双径现象消失（Ａ组）５１例；仍有双径现象，但无心房回波（Ｂ组）２１例；有双径现象，且有１个心房回波（Ｃ组）８例。消融成功后观察３０ｍｉｎ，急性复发４例（５．８％）；术后随访１４．７±５．６（６～３９）个月慢性复发３例（３．８％），共复发７例（８．８％）。７例中，Ａ组与Ｂ组各２例、Ｃ组３例，复发率分别为３．９％、９．５％、３７．５％。其中Ａ组与Ｃ组比较复发率差异非常显著（Ｐ＜０．０１），其余差异无显著性（Ｐ＞０．０５）。此结果表明，选用三种终点中的任何一种，术后大多数患者都未复发。而为了降低复发率，除了消融成功后至少应观察３０ｍｉｎ以消除急性复发外，在技术成熟的单位，可力争以双径现象消失为改良术终点。
The correlation between the different electrophysiologic ends of radiofrequency atrioventricular node (AVN) modification and the recurrence rate of atrioventricular nodal reentrant tachycardia(AVNRT) were studied in 80 patients with AVNRT successfully treated with radiofrequency AVN modification.Of them,51 patients had no the dual AVN pathway (Group A),21 patients had the jump atrioventricular conduction without an atrial echo (Group B) and 8 patients had the jump atrioventricular conduction with an atrial echo (Group C). AVNRT recurred acutely on 4 patients (5.8%) during 30 minuts after the first successful radiofrequency ablation and chronically on 3 patients (3.8%) in 14.7±5 6(6～39) months fallow up duration after successful operation.There was the total recurrent rate 8.8%(7/80).The recurrence rate was 3.9% (2/51) in Group A,9.5%(2/21) in Group B and 37.5%(3/8) in Group C.There was significant variables ( P <0.01) between Group A and Group C.The results showed that most patients had no recurrence of AVNRT after successful radiofrequency AVN modification with any one of the three ends.But for a lower recurrence rate of AVNRT,a doctor with rich experience of radiofrequency AVN modification should have the end without the dual AVN pathways;besides,a patient should be surveyed at least 30 minuts.
