经食管心房调搏检查经食管心房调搏检查transesophag?eal atrial pacemaker check食管下端贴近左房，故该方法为间接左房调搏。近年儿科已广泛应用于心脏电生理检查。临床应用于下列情况：①检查窦房结功能：可测定窦房结恢复时间，校正窦房结恢复时间及窦房传导时间。儿童正常值分别为913.3±139.7ms，(247.7±51.3）ms及(102.5±18.6）ms。②评价房室传导功能：可测定文氏阻滞点、2∶1阻滞点、房室功能不应期和有效不应期。③检测房室结双径路：正常儿童23.6%存在房室结双径路。④研究室上性心动过速的折返机制：经食管心房调搏可诱发窦房结、房内、房室交界区及房室旁路折返性室上性心动过速。同步描记食管心电图及V1导联心电图，可分辨P波形态、心房激动顺序，测定RP、PR间期及房室传导曲线，明确室上性心动过速的不同折返机制，并选择有效的药物治疗。⑤对预激综合征可进行以下检查：检出房室旁道，确诊隐性预激综合征；测定旁道不应期，初筛高危患者。儿童旁道不应期＜220ms者，房颤发生率高，易致室颤，为高危患者。⑥应用食管心房调搏超速抑制方法终止室上性心动过速发作。⑦研究抗心律失常药的电生理作用，并观察疗效。
