The results of transoesophageal atrial stimulation (TAS) were retrospectively evaluated in 22 patients (13 women, nine men, mean age forty-five years), in whom the method was used in the process of diagnosing or specifying supraventricular arrhythmias. The patients were tested for corrected sinus node recovery time, the response to incremental stimulation and burst pacing. TAS resulted in a pathological outcome in 11 patients (50%). Among 14 patients suffering from unprovoked palpitations suspicious of tachyarrhythmias TAS was able to induce a pathological response in 10 patients (71%). In five of eight patients (63%) with inducible SVT, this arrhythmia had not previously been observed. TAS was able to induce atrial fibrillation in four of eight patients with an accessory pathway. Typical symptoms rather than a prior pathological electrocardiography (12-lead ECG, Holter-monitoring, exercise-ECG) was able to predict the outcome of TAS (p < 0.05). We conclude that TAS is a safe and suitable supplement in the evaluation of supraventricular arrhythmias; primarily among patients with characteristic symptoms.
对22例患者（13例女性，9例男性，平均年龄45岁）经食管心房刺激（TAS）的结果进行了回顾性评估，这些患者在诊断或明确室上性心律失常过程中采用了该方法。对患者进行了校正窦房结恢复时间、递增刺激反应和短阵猝发刺激测试。TAS在11例患者（50%）中导致了病理性结果。在14例无故心悸且怀疑有心律失常的患者中，TAS在10例患者（71%）中诱发了病理性反应。在8例可诱发室上性心动过速（SVT）的患者中，有5例（63%）此前未观察到这种心律失常。TAS在8例有旁路的患者中能诱发4例房颤。典型症状而非先前的病理性心电图（12导联心电图、动态心电图监测、运动心电图）能够预测TAS的结果（p<0.05）。我们得出结论，TAS是评估室上性心律失常的一种安全且合适的补充方法；主要适用于有特征性症状的患者。
