胃电图（EGG），其中胃的平滑肌层的电活动通过腹壁被持续记录，近年来已被应用于人类作为一种非侵入性的方法。在马的急腹症中，使用EGG分析消化活动被认为在诊断上有用。通过比较赛拉嗪给药后经皮ECG方法的结果与使用长期附着于盲肠浆膜的应变计力传感器（力传感器）获得的结果，检查了心电图（ECG），以确定其在评价马消化动力方面的有效性。作为受试者，测试使用了六只雄性纯种马（平均体重：457.5 +/- 9.2 kg）。测试显示ECG中盲肠经皮电位和力传感器测量的盲肠收缩均降低。甲苯噻嗪给药后，振幅相对于对照期的平均降低率分别为17.8 +/- 3.4%和20.0 +/- 4.6%，表明两种方法之间存在显著相关性（r=0.90）。另一方面，在EGG的傅里叶变换（FFT）分析中，功率分布集中在每分钟6个周期左右，认为与力传感器观察到的收缩频率（每分钟5.4 +/- 3.0）相似。甲苯噻嗪给药后，ECG中运行频谱总功率的总频带（1.8-12周期/min）降至甲苯噻嗪值的37.0 +/- 5.1%。基于这些发现，似乎ECG电位反映了盲肠起源的电活动，表明ECG在经皮评价马盲肠运动方面具有较高的临床适用性。
Electrogastrography (EGG), in which the electrical activity of the smooth muscular layer of the stomach is recorded percutaneously through the abdominal wall, has been applied in recent years to humans as a non-invasive method. In acute abdominal disease in horses, it is considered diagnostically useful to analyze digestive activity using EGG. Electrocecography (ECG) was examined to determine its effectiveness in evaluating equine digestive motility through comparison, after xylazine administration, between the results of the percutaneous ECG method and the results obtained using a strain-gauge force transducer (Force Transducer) chronically attached to the serous membrane of the cecum. As subjects, the test used six male thoroughbreds (average weight: 457.5 +/- 9.2 kg). The test showed a reduction in both the percutaneous electrical potential of the cecum in ECG and in cecal contractions measured with the Force Transducer. After xylazine administration, an average rates of decrease of the amplitude from the control period were 17.8 +/- 3.4% and 20.0 +/- 4.6% respectively, demonstrating a significant correlation (r=0.90) between the two methods. On the other hand, power distribution centered around 6 cycles per minute in a Fourier transform (FFT) analysis of EGG, thought similer to the contraction frequency of 5.4 +/- 3.0 per minute observed with the Force Transducer. After xylazine administration, the total frequency band (1.8-12 cycle per min) in the running spectrum total power in ECG decreased to 37.0 +/- 5.1% of the pre-xylazine value. Based on these findings, it appears that the ECG potential reflected electrical activity of cecal origin, suggesting high clinical applicability of ECG to the percutaneous evaluation of equine cecal motility.
