经食道心房调搏检查心肌炎患儿36例,结果:SACTc延长11例,cSNRT延长7例,SNRT延长3例;AVERP延长15例,AVFRP延长6例,文氏、2:1阻滞点降低分别为13、14例。SACT延长有5例与AVERP延长并存,AVERP延长者几乎与文氏,2:1阻滞点均降低。房室结功能异常的心电图表现主要为束支传导阻滞,其次为ST及T波改变;窦房结功能异常的心电图表现主要为窦房结传导阻滞。异常电生理患者仅有4例在1～3周内发病,大多在1月以上,最长1～2年,有心脏扩大者均有电生理异常。 Transient esophageal atrial pacing in 36 children with myocarditis, the results: SACTc extended in 11 cases, cSNRT prolonged in 7 cases, SNRT extended in 3 cases; AVERP extended in 15 cases, AVFRP extended in 6 cases, Venn and 2: 1 block points decreased 13,14 cases. SACT extended in 5 cases and AVERP prolonged coexistence, AVERP prolongation were almost with Wen, 2: 1 block points were reduced. Abnormal ECG findings of atrioventricular node were mainly bundle branch block, followed by changes of ST and T wave. Electrocardiogram of sinoatrial node dysfunction mainly showed conduction block of the sinus node. Only 4 patients with abnormal electrophysiology in 1 to 3 weeks of onset, mostly in January above, up to 1 to 2 years, there are electrophysiological abnormalities were enlarged heart.
