Alvarez等人于1922年首次从人体体表记录到胃电活动。嗣后,许多学者即设想利用胃电作为胃的生理活动指标,研究胃的生理、病理规律,并希望将其作为诊断胃脏疾患及观察疗效的指标。以往,由于引导胃电技术方面的困难,由胃电获得的信息有限,因此,研究进展较慢。近十余年来,随着无线电电子学技术的发展以及对胃肠道平滑肌电生理特征研究的深入,从而引起广大科学工作者的广泛兴趣,目前已成为一个比较活 Alvarez and others in 1922 for the first time recorded from the human body surface to gastric activity. Subsequently, many scholars envisaged the use of gastric electrical activity as a physiological indicator of the stomach to study the physiology and pathology of the stomach, and hope it will be used as an indicator of gastric disorders and to observe the efficacy. In the past, due to the difficulty of guiding the technique of gastroscopy, the information obtained from the gastrocnemius was limited, therefore, the research progress was slow. In recent ten years, with the development of radio electronic technology and the research on electrophysiological characteristics of gastrointestinal smooth muscle, which has aroused widespread interest of scientists, it has become a relatively live
