近来有报道侧脑室内注射五肽胃泌素可使胃肠道推进运动增强,静脉注入胃泌素后可翻转心脏对肾上腺素的反应,提示胃泌素对植物神经系统功能有一定作用。但至今尚未见报道胃泌素对心脏电活动有何影响。木文以肌肉或侧脑室注射五肽胃泌素对心肌细胞动作电位幅
Recent reports of intracerebroventricular injection of pentagastrin can increase gastrointestinal motility, intravenous gastrin reverses the heart’s response to epinephrine, suggesting that gastrin has a role in autonomic nervous system function. However, no reports have been made on the effects of gastrin on cardiac electrical activity. Woody muscle or lateral ventricle injection of pentagastrin cardiomyocyte action potential amplitude
