腺苷试验对阵发性室上性心动过速患者诱发隐匿性预激综合征的研究

目的：探讨静脉注射腺苷试验对阵发性室上性心动过速（ PSVT ）患者诱发隐匿性预激综合征的检出率。方法静脉注射腺苷试验对45例PSVT患者和45名无PSVT者（对照组）能否诱发出预激（δ）波进行分析。结果45例患者在静脉注射腺苷试验中诱发出预激（δ）波43例（95.55％），对照组45名诱发出预激（δ）波2例（4.44％），P＜0.01。结论腺苷试验对PSVT患者可诱发出预激（δ）波，可诊断隐匿性预激综合征。

Study on concealed pre-excitation syndrome induced by adenosine test in patients with paroxysmal supravent-riclar tachycardia

Objective To study the detection rate of concealed pre-excitation syndrome induced by intrave-nous injection of adenosine in patients with paroxysmal supraventriclar tachycardia .Methods The intravenous injec-tion of adenosine were performed in 45 patients with paroxysmal supraventriclar tachycardia and 45 healthy people （healthy control group） to investigate the Delta（δ） wave.Results During Intravenous injectiion of adenosine （Del-ta,δ） wave was detection in 43 patients（95.55%） in 45 patients with paroxysmal supraventriclar tachycardia ,and this wave was found in 2 patients（4.44%） in healthy group,which showed significant differences （P〈0.01）.Con-clusion The adenosine test for patients with paroxysmal supraventriclar tachycardia can induce Delta （δ） wave,and can be helpful to diagnosis of concealed pre-excitation syndrome .
