Electromyographic responses of the canine-pyeloureter to dobutamine, a beta 1-adrenoceptor agonist were investigated in vitro. Dobutamine produced a marked enhancement of potential in the pelvicalyceal (PC-) border, but failed to evoke noticeable responses in the renal pelvis and ureter. Dobutamine, however, made the pacemaker rhythm a little slow. This finding shows that the renal pacemaker is somewhat different form the cardiac pacemaker, pace of which is quickened by dobutamine.
在体外研究了β1肾上腺素能受体激动剂多巴酚丁胺对犬肾盂输尿管的肌电图反应。多巴酚丁胺使肾盂（PC）边缘的电位显著增强，但未能在肾盂和输尿管中引起明显反应。然而，多巴酚丁胺使起搏器节律稍有减慢。这一发现表明，肾脏起搏器与心脏起搏器有所不同，心脏起搏器的节律会被多巴酚丁胺加快。
