ECG was recorded in 38 patients with achalasia of the esophagus before, during and after pneumatic dilatation. During the dilatation both marked increases as well as decreases of heart frequency were observed. The mean values of all patients remained virtually unchanged. The most frequent type of arrhythmia were ventricular extrasystolies (16 patients), whereas supraventricular extrasystolies (4 patients), second degree-av-block (2 patients) and av-dissociation (1 patient) occured infrequently. In none of our patients arrhythmia was critical, even in a patient with preexisting cardiac insufficiency. Thus, patients with achalasia of the esophagus are not endangered to a major degree by cardiac arrhythmia during pneumatic dilatation.
对38例食管贲门失弛缓症患者在气囊扩张术前、术中和术后进行了心电图记录。在扩张过程中，观察到心率显著增加和降低。所有患者的平均值基本保持不变。最常见的心律失常类型是室性期前收缩（16例患者），而室上性期前收缩（4例患者）、二度房室传导阻滞（2例患者）和房室分离（1例患者）较少见。在我们的患者中，即使是已有心脏功能不全的患者，心律失常也不严重。因此，食管贲门失弛缓症患者在气囊扩张期间不会受到严重的心律失常威胁。
