阵发性室上性心动过速(PSVT)常规心电图不易捕捉到,本文对12例疑有PSVT患儿进行食道心房调搏检查,10例诱发出室上速,现报告如下.临床资料一、一般资料:收治12例患儿均有反复发作心慌、胸闷史,男女各6例,年龄8～14岁;病史半个月～10年,起病最早年龄2岁,发作频繁者每月1～2次,发作持续时间短者1～3小时,最长达15小时.入院时心电图正常7例,室上速2例,预激综合征3例,全部患儿经检查无器质性心脏病.二、方法与结果:用CF—4型多功能心脏电生理程控刺激仪(苏州产品),心电监护并记录,导管深27～35cm,电压17～25V,刺激方法用S_1S_1、RS_2、S_1S_2或再加S_3刺激.12例患儿诱发出室上速10例(附表),其中房室折返性心动过速6例(1～6),房室结
Paroxysmal supraventricular tachycardia (PSVT) conventional ECG is not easy to capture, 12 cases of suspected PSVT in children with esophageal atrial pacing examination, 10 cases of induced supraventricular tachycardia, are as follows.Clinical data, General information: 12 patients admitted to recurrent episodes of palpitation, chest tightness history, 6 males and 6 females, aged 8 to 14 years; history of half a month to 10 years, the earliest onset age of 2 years, frequent seizures 1 ~ 2 times, short duration of attack 1 to 3 hours, up to 15 hours on admission, normal electrocardiogram in 7 cases, 2 cases of supraventricular tachycardia, pre-excitation syndrome in 3 cases, all children after examination without structural heart disease Methods and Results: The CF-4 multifunctional cardiac electrophysiology program stimulator (Suzhou product) was used to monitor and record the ECG. The catheter depth was 27-35cm and the voltage was 17-25V. The stimulation method was S_1S_1, RS_2, S_1S_2 Or S_3 stimulation.Of the 12 cases, 10 cases of supraventricular tachycardia were induced (schedule), including 6 cases of atrioventricular reentrant tachycardia (1 ~ 6), atrioventricular node
