In 9 voluntary test persons with a sound heart comparative examinations were carried out to discover the optimum depth of insertion by unipolar and bipolar determination of the absolute threshold and transoesophageal derivation as well as the correlation of the optimum depth of insertion with external measurements of the body. The methods mentioned to ascertain the optimum depth of insertion are equivalent concerning the bipolar arrangement of the electrodes in the oesophagus. The average effective depth of insertion can simplified be defined. A correlation of the average effective depth of insertion concerning external measurements of the body could not be found, so that the conscientious discovering of the optimum depth of insertion is a necessity for every patient. The average value found could attain an orientating importance with the primary placing of the probe concerning the average effective depth of insertion of 37 cm.
对9名心脏健康的志愿者进行了对比检查，通过单极和双极测定绝对阈值、经食管导联来确定最佳插入深度，以及最佳插入深度与身体外部测量值之间的相关性。就食管中电极的双极排列而言，上述确定最佳插入深度的方法是等效的。平均有效插入深度可以简化定义。未发现平均有效插入深度与身体外部测量值之间存在相关性，因此为每位患者认真确定最佳插入深度是必要的。所发现的平均值对于探头初次放置时的平均有效插入深度37厘米可能具有一定的指导意义。
