T1 - Second‐degree interatrial block: Brief review and concept Y1 - 2018 SN - 1082-720X UR - http://hdl.handle.net/11268/7581 AB - The advanced interatrial block (A‐IAB) (P ≥ 120 ms plus ± pattern in II, III and aVF) corresponds at atrial level, to right or left advanced bundle branch block at ventricular level, and it is well known that these patterns may be seen transiently in relation to taquicardia or bradycardia (tachycardia or bradycardia dependent right or left bundle branch block). We present for the first time, the same phenomenon at atrial level. In one case, the A‐IAB appears in relation to tachycardization and in the other disappears during a pause induced by ventricular premature complex.
