A 76-year-old woman, affected by drugs resistant focal atrial tachycardia, underwent a catheter ablation procedure in our Hospital. During ablations we observed on the surface ECG a progressive modification of the second component of the P wave (delayed and then negative in inferior leads). These findings demonstrated, compared to the beginning of the procedure, a different propagation of the activation wave from the right to the left atrium, helped to identify the true origin of a focal atrial tachycardia. Moreover, this case underlined the importance of the Bachmann's bundle for the impulse propagation through the interatrial septum in normal hearts.
一名76岁女性,患有耐药性局灶性房性心动过速,在我院接受了导管消融手术。在消融过程中,我们在体表心电图上观察到P波第二个成分的逐渐改变(在下壁导联中延迟然后变为负向)。与手术开始时相比,这些发现表明激动波从右心房到左心房的传播有所不同,有助于确定局灶性房性心动过速的真正起源。此外,该病例强调了巴赫曼束在正常心脏中通过房间隔进行冲动传导的重要性。
