心律失常是Wallenberg综合征的罕见表现;病变位于脑干,尤其是延髓下部,调节交感神经和副交感神经活动。一名55岁的男子被送往大学医院,症状包括共济失调,左上眼睑,右侧疼痛和温度降低的感觉,左侧面部麻木,和头晕。脑磁共振成像显示左延髓背外侧梗死。因此,他被诊断出患有Wallenberg综合征.在他因Wallenberg综合征接受保守治疗时,他经历了几次自我限制的心脏跳动事件,这需要心脏功能的评估。24小时Holter监护仪显示RR间期增加,伴有心动过缓和窦性停顿延长。因此,诊断为病窦综合征合并Wallenberg综合征。病态窦房结综合征是Wallenberg综合征的一种罕见心脏并发症,当最初的心电图显示窦性心律正常时,临床医生可能会忽略它。如果没有适当的医疗干预,病态窦房结综合征可导致猝死。因此,临床医生应考虑进一步评估,包括一个24小时Holter监视器,以检查Wallenberg综合征急性期是否存在病态窦房结综合征。
Cardiac arrhythmia is a rare manifestation of the Wallenberg syndrome; lesions are located in the brainstem, especially the lower medulla, which regulates sympathetic and parasympathetic activity. A 55-year-old man was admitted to the university hospital with symptoms including ataxia, left ptosis, decreased sensation of pain and temperature on the right side, left facial numbness, and dizziness. Brain magnetic resonance imaging revealed an infarction in the left dorsolateral medulla. Therefore, he was diagnosed with Wallenberg syndrome. While he underwent conservative treatment for Wallenberg syndrome, he experienced several events of self-limiting heart pounding, which required an evaluation of cardiac function. The 24-hour Holter monitor showed an increased RR interval with bradycardia and prolonged sinus pause. As a result, the diagnosis of sick sinus syndrome combined with Wallenberg syndrome was made. Sick sinus syndrome is a rare cardiac complication of the Wallenberg syndrome, and clinicians could overlook it when the initial electrocardiography shows a normal sinus rhythm. Sick sinus syndrome can cause sudden death without appropriate medical intervention. Therefore, clinicians should consider further evaluation, including a 24-hour Holter monitor, to check for the potential presence of sick sinus syndrome in the acute phase of Wallenberg syndrome.
