Bayés syndrome and acute cardioembolic ischemic stroke

Figure 1 Scheme of the anatomo-electrophysiologic features of the Bayés syndrome[27]. AVN: AV node; BB: Bachmann bundle; IAB: Interatrial block; LBB: Left bundle branch; RBB: Right bundle branch; SN: Sinus node.

Figure 2 A 55-year-old male diagnosed with Bayés syndrome, with a history of paroxysmal atrial fibrillation showing normal values of echocardiographic measurements, except for a discrete left atrial enlargement (40 mm). ECG shows the presence of advanced interatrial block. P-wave duration is wide (120 ms) and biphasic in inferior leads (II, III and aVF). ECG: Electrocardiogram.
