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.
高级房内阻滞(A-IAB)(P≥120毫秒,且在II、III和aVF导联呈±型)在心房层面相当于心室层面的右或左束支高级阻滞,并且众所周知,这些图形可能与心动过速或心动过缓(心动过速或心动过缓依赖性右或左束支阻滞)相关而短暂出现。我们首次在心房层面呈现了同样的现象。在1例中,A-IAB与心动过速化相关出现,而在另一例中,其在室性早搏诱发的长间歇期间消失。
