胃的电活动控制胃的收缩,而类似于胃麻痹这样的胃功能性疾病与胃的机械蠕动(收缩)有密切的关系。胃蠕动时可以用置于胃粘膜上的测压计进行损伤性测量,而抑制胃收缩的胃电信号则可以利用表皮电极无损伤地进行测量。本文采用体表电极记录胃电信号来研究水和固态食物对胃电活动的影响。作者采用改进的记录方法,对记录信号进行了功率谱分析和统计分类。记录信号分为:进食前、饮水后和进食后。同时记录了胃麻痹患者的表皮胃电信号和压力信号,以便进行对比研究更有效地证明水和固态食物对胃电慢波及胃蠕动的影响,实验结果表明,水并不诱发胃的收缩,但使得胃慢波幅度和频率都提高。进食后胃电幅度的提高是胃收缩及胃扩张后使胃
Gastric electrical activity controls gastric contractions, and gastric functional disorders such as gastric paralysis are closely related to the mechanical peristalsis (contraction) of the stomach. Gastric peristalsis can be placed on the gastric mucosa on the manometer to measure the damage, while the inhibition of gastric contraction of the gastric electrical signal can be epidermal electrodes without damage measurements. In this paper, the body surface electrode recording gastric electrical signal to study the water and solid food on gastric electrical activity. The author uses improved recording methods, the recorded signal power spectrum analysis and statistical classification. Record the signal is divided into: before eating, after drinking water and after eating. At the same time, we recorded epidermal gastric signal and pressure signal in patients with gastric paralysis so as to compare the effects of water and solid food on gastric motility and gastric motility more effectively. The experimental results show that water does not induce gastric contraction, Make gastric slow wave amplitude and frequency are increased. Increased gastric electrical amplitude after eating stomach contraction and gastric dilatation
