BACKGROUND Bradycardia and syncope are known sequelae of brain lesions. However, in the absence of neurological signs and symptoms, bradycardia and syncope are often investigated purely from the cardiovascular perspective and central nervous system-related causes may be easily overlooked during differential diagnosis. CASE PRESENTATION Here we report a case of a 69-year-old Caucasian man who presented to the emergency department after a fall. He had 1-year history of syncope and bradycardia with frequent ectopic beats shown on his electrocardiogram. He had no neurological symptoms. He was previously investigated as an out-patient and a diagnosis of idiopathic bradycardia with ventricular ectopic beats was made. On admission, cardiovascular investigations could not reveal the cause of his bradycardia. Computed tomography and magnetic resonance imaging scans of his head showed a localized mass in left basal ganglia consistent with infiltrating glioma. CONCLUSION To the best of our knowledge this is the first case report demonstrating central nervous system-related bradycardia and syncope without other neurological symptoms. This case will serve as a useful reminder to general practitioners, accident and emergency doctors, and cardiologists.

心动过缓和晕厥是颅骨病变的唯一表现：一例病例报告。

背景技术心动过缓和晕厥是已知的脑损伤后遗症。然而，在缺乏神经系统症状和体征的情况下，通常仅从心血管的角度来研究心动过缓和晕厥，并且在鉴别诊断中很容易忽略与中枢神经系统相关的原因。病例介绍这里我们报告一例69岁高加索人跌倒后到急诊室就诊的情况。他有1年晕厥和心动过缓的病史，心电图显示有频繁的异位搏动。他没有神经系统症状。先前曾在门诊接受过调查，并诊断为特发性心动过缓并伴有室性异位搏动。入院时，心血管检查无法揭示其心动过缓的原因。他的头部的计算机断层扫描和磁共振成像扫描显示左基底神经节中有局部肿块，与浸润性胶质瘤一致。结论据我们所知，这是第一例病例报告，显示了中枢神经系统相关的心动过缓和晕厥，没有其他神经系统症状。这种情况将为全科医生，事故和急诊医生以及心脏病专家提供有益的提醒。
