Three cases are reported who have short runs of atrial premature contractions (APCs) induced by swallowing and cough. The occurrence of the APCs were affected by autonomic nervous system in all cases. The precipitating factor is considered to be the increase of vagal tone in case 1, sympathetic tone in case 2 and both of them in case 3. The autonomic mechanism of swallowing-induced tachycardia could be divided into three categories and the treatment of these arrhythmias might be different in each group. Pharmacological autonomic blockade with atropine and propranolol is useful to reveal the underlying autonomic mechanisms.
报告了3例吞咽和咳嗽诱发短阵房性早搏（APC）的病例。所有病例中APC的发生均受自主神经系统影响。在病例1中，诱发因素被认为是迷走神经张力增加；病例2中是交感神经张力增加；病例3中是两者均增加。吞咽诱发心动过速的自主机制可分为三类，每组这些心律失常的治疗可能有所不同。使用阿托品和普萘洛尔进行药理学自主神经阻滞有助于揭示潜在的自主神经机制。
