采用食管心房调搏对已证实或疑有室上速（ＳＶＴ）患儿进行检测，共诱发ＳＶＴ１８例。其中２例自发出现ＳＶＴ，且程控电刺激不能终止，ＲＰ＇／Ｐ＇Ｒ＞１，诊断为房性自律性增高性心动过速；１６例均能被电刺激诱发和终止，ＲＰ＇／Ｐ＇Ｒ＜１。该１６例中１例ＲＰ＇为５０ｍｓ，且诱发ＳＶＴ前有Ｓ２Ｒ跳跃式延长（≥６０ｍｓ），诊断为房室结折返性心动过速；另１５例ＲＰ＇＞８５ｍｓ，诊断为房室折返性心动过速。诱发ＳＶＴ以Ｓ１Ｓ２早搏刺激法较敏感，终止ＳＶＴ以Ｓ１Ｓ２Ｓ３早搏刺激法成功率最高，且重复性好。
The use of esophageal atrial pacing has been confirmed or suspected of supraventricular tachycardia (SVT) in children were detected, a total of 18 cases of SVT induced. Two cases of spontaneous SVT, and programmed electrical stimulation can not be terminated, RP ’/ P’R> 1, diagnosis of atrial tachycardia increased self-discipline; 16 cases were induced and terminated by electrical stimulation, RP’ / P ’R <1. One of the 16 patients had a RP ’of 50 ms and had an episode of S2R lengthening (≥60 ms) prior to SVT, a diagnosis of atrioventricular nodal reentrant tachycardia; the other 15 cases of RP’> 85 ms were diagnosed as atrioventricular reentrant Tachycardia. SVT induced by S1S2 premature stimulation more sensitive to terminate the SVT to S1S2S3 premature beat stimulation the highest success rate, and good reproducibility.
