摘要: 目的 探讨房室结折返性心动过速(AVNRT) 患者在窦性心律时静注三磷酸腺苷(ATP) 非侵入性诊断房室结双径路(AVNDP) 的价值及对射频消融(RFCA)结果的评价。方法 研究组(45 例) 系自发或能被诱发出持续性AVNRT 患者;对照组(37 例) 为成功接受了RFCA 的房室折返性心动过速(AVRT) 患者。在窦性心律时静注递增剂量的ATP (10~40 mg), 出现连续两次心搏之间AH 跳跃≥50 ms 或诱发出AVNRT 者认为存在AVNDP。结果 4 例患者(研究组和对照组各2 例) 由于不能耐受ATP 而被剔除。研究组43 例中, 按心内电生理标准诊断AVNDP 者38 例(88%), 静注ATP 后出现AVNDP者36 例(84%);对照组35 例静注ATP 后仅有1 例(3%) 出现AVNDP (P<0.01)。从体表心电图记录分析的结果与心内电图记录分析的结果一致。对成功地接受RFCA 的28 例患者重复了ATP 试验, 结果AVNDP 消失者在慢径路消融的20 例患者中有19 例(95%);在慢径路改良的8 例患者中仅有3 例(38%), (P<0.01)。结论 ATP 试验是诊断AVNDP 的一个有价值的非侵入性床旁试验方法, 也是判断慢径路消融结果的可靠方法。

Abstract: Aim To assess the value of the administration of adenosine-5'-triphosphate (A TP) during sinus rhythm for noninvasive diagnosis of AV node dual pathways(AVNDP) and aboli tion or modification of the slow pathway (SP) after radiof requency (RFCA) in patient s with inducible sustained AVNRT.Methods Incremental doses of ATP were int ravenously administ rated during sinus rhy thm to patients with spontaneous or inducible sustained AVN RT (study group, n=45) and to patients with no evidence of AVNDP or inducible AVNRT (control group, n= 37) until ECG sig ns of AVNDP (50 ms increase or decrease in P-R interval in two consecutive beats, or occurrence of AVNRT) or second-degree AV block were observed.Results Four patients (two in study patient s and two in co nt rol patients) could not complete the t rial and were excluded from analysis. AVNDP was observed by ATP in 36(84%) study patients, whereas it was diagnosed by electrophy siology criteria in 38(88%) patients.AVNDP was observed only in 1(3%) control patient.AVNDP by ATP test was disappeared in 18(90%) of 20 patients who underwent SP abolition and in 3 (38%) of 8 patients who underwent SP modification.Conclusion ATP test during sinus rhythm enables noninvasive diagnosis of AVNDP in a high percentage of patients with inducible AVN RT and reliably confirms the Results of RFCA of the SP.
