Bayés syndrome is an under-recognized clinical condition characterized by advanced interatrial block. Bayés syndrome is a subclinical disease that manifests electrocardiographically as a prolonged wave duration > 120 ms with biphasic morphology ± in the inferior leads. The clinical relevance of Bayés syndrome lies in the fact that is a clear arrhythmological syndrome and has a strong association with supraventricular arrhythmias, particularly atypical atrial flutter and atrial fibrillation. Likewise, Bayés syndrome has been recently identified as a novel risk factor for non-lacunar cardioembolic ischemic stroke and vascular dementia. Advanced interatrial block can be a risk for embolic stroke due to its known sequelae of left atrial dilation, left atrial electromechanical dysfunction or atrial tachyarrhythmia (paroxysmal or persistent atrial fibrillation), conditions predisposing to thromboembolism. Bayés syndrome may be responsible for some of the unexplained ischemic strokes and shall be considered and investigated as a possible cause for cryptogenetic stroke. In summary, Bayés syndrome is a poorly recognized cardiac rhythm disorder with important cardiologic and neurologic implications.
贝耶斯综合征是一种未被充分认识的临床病症，其特征为存在高度房间阻滞。贝耶斯综合征是一种亚临床疾病，心电图表现为下壁导联中波时限延长>120毫秒且呈双向形态±。贝耶斯综合征的临床意义在于它是一种明确的心律失常综合征，与室上性心律失常密切相关，尤其是不典型房扑和房颤。同样，贝耶斯综合征最近被确定为非腔隙性心源性栓塞性缺血性卒中及血管性痴呆的一个新危险因素。高度房间阻滞因其已知的左房扩大、左房机电功能障碍或房性快速心律失常（阵发性或持续性房颤）后遗症，可成为栓塞性卒中的一个危险因素，这些情况易导致血栓栓塞。贝耶斯综合征可能是一些不明原因缺血性卒中的病因，应作为隐源性卒中的一个可能原因加以考虑和研究。总之，贝耶斯综合征是一种认识不足的心律失常疾病，具有重要的心脏和神经学意义。
