Abstract
The ability of transcutaneous recordings of gastric electrical activity to detect gastric electrical abnormalities was determined by simultaneous measurements of gastric electrical activity with surgically implanted serosal electrodes and cutaneous electrodes in six patients undergoing abdominal operations. Transient abnormalities in gastric electrical activity were seen in five of the six patients during the postoperative period. Recognition of normal gastric electrical activity by visual analysis was possible 67% of the time and with computer analysis 95% of the time. Ninety four per cent of abnormalities in frequency were detected by visual analysis and 93.7% by computer analysis. Abnormalities involving a loss of coupling, however, were not recognised by transcutaneous recordings. Transcutaneous recordings of gastric electrical activity assessed by computer analysis can usually recognise normal gastric electrical activity and tachygastria. Current techniques, however, are unable to detect abnormalities in electrical coupling.
摘要
通过对6例接受腹部手术患者同时使用手术植入的浆膜电极和皮肤电极测量胃电活动，来确定经皮记录胃电活动检测胃电异常的能力。6例患者中有5例在术后出现胃电活动的短暂异常。通过视觉分析识别正常胃电活动的时间为67%，通过计算机分析为95%。通过视觉分析检测到94%的频率异常，通过计算机分析为93.7%。然而，经皮记录未识别出涉及耦合丧失的异常情况。通过计算机分析评估的胃电活动经皮记录通常能够识别正常胃电活动和胃动过速。然而，目前的技术无法检测电耦合异常。
