We experienced a case of sinus arrest probably induced by right stellate ganglion block (SGB). A healthy medical student volunteered in our study of the cardiac autonomic nervous system and received the SGB. After the Holter ECG had been attached, the SGB was performed with mepivacaine 8 ml. Horner's sign was observed after about 3 minutes. A transient (15 s) sinus arrest occurred suddenly after about 6 minutes of the tilt test probably due to a vasovagal reflex, and the subject lost consciousness. From spectral analysis of the Holter ECG recording, the right SGB may be closely involved in the induction of the sinus arrest. Our present case suggests that sinus arrest may occur if a patient stands up after right SGB.
我们遇到了一例可能由右侧星状神经节阻滞（SGB）诱发的窦性停搏病例。一名健康的医学生自愿参与我们关于心脏自主神经系统的研究并接受了SGB。在连接动态心电图（Holter）后，用8毫升甲哌卡因进行了SGB。大约3分钟后观察到霍纳氏征。在倾斜试验约6分钟后突然发生了短暂（15秒）的窦性停搏，可能是由于血管迷走反射，受试者失去了意识。从Holter心电图记录的频谱分析来看，右侧SGB可能与窦性停搏的诱发密切相关。我们目前的病例表明，右侧SGB后如果患者站立可能会发生窦性停搏。
