【摘要】 目的：评价程控刺激（ＰＥＳ）在儿科临床应用的价值。方法：通过ＰＥＳ检测室上性心动过速（ＰＳＶＴ）１６０例。结果：①１６０例ＰＳＶＴ分别由：房室折返性心动过速（ＡＶＲＴ）７８例（４８７５％）、房室结折返性心动过速（ＡＶＮＲＴ）６９例（４３１２５％）、复合型折返性心动过速６例（３５７５％）和房内折返性心动过速（ＩＡＲＴ）７例（４３７５％）构成；②ＰＥＳ能快速鉴别各类型ＰＳＶＴ，并了解其形成机理及折返途径；③２０例顺向性房室折返性心动过速患儿静脉推注心律平后经ＰＥＳ检测有１６例不再诱发心动过速，其用药后的旁道前传有效不应期（ＡＰＥＲＰ）有显著延长（Ｐ＜００１）。结论：ＰＥＳ是目前儿科临床诊断ＰＳＶＴ颇有价值的检测手段更多还原

【Abstract】 Objective:To evaluate programmed electrical stimulation(PES) in diagnosis of paroxysmal supraventricular tachycardia (PSVT).Method:160 cases with PSVT were examined by PES.Results:Among 160 cases there were 78 cases (48.75%) with atrioventricular reentry tachycardia(AVRT),69 cases (43.125%) with atrioventricular node reentry tachycardia(AVNRT),6 cases(3.75%) with complex reentry tachycardia(CRT) and 7 cases (4.375%) with intraartrial reentry tachycardia (IART);PES can quickly distinguish all kinds of PSVT and detect the forming mechanism and reentry path;20 cases with OAVRT were treated with propafenone and 16 of them could not be induced to OAVRT with PES.Conclusion:PES is a valuable method of diagnosing PSVT.更多还原
