目的 探讨经食管左心房调搏术 (TEAP)在小儿心脏病特别是病毒性心肌炎的非创伤性诊断中的应用价值。方法 用S1-S2 对 46例正常儿童及 5 6例心脏疾病患儿进行了房室结不应期的测定。结果 ① 6个月至 3岁组患儿上述参数与正常组相比无显著性差异 ;②～ 7岁组患儿FP、RRP及～ 13岁组患儿FP、ERP、FRP、RRP与正常组相比 ,均明显延长 ,有显著性差异。结论 TEAP可用于小儿心脏病的辅助诊断 ,可以发现常规心电图不能显示的房室结受损情况。
Objective To investigate the value of transesophageal left atrial pacing (TEAP) in noninvasive diagnosis of pediatric heart disease, especially viral myocarditis. Methods S1-S2 in 46 cases of normal children and 56 cases of heart disease in children with atrioventricular node refractory period was measured. Results ① There was no significant difference between the 6-month-old and 3-year-old children in the above parameters compared with the normal group. ② FP, RRP and FP-RRP in children aged 7 to 7 years old were significantly higher than those in normal group Compared with the control group, it was significantly prolonged with significant difference. Conclusion TEAP can be used in the diagnosis of pediatric heart disease, and can be found in conventional ECG can not be displayed atrioventricular node damage.
