本文报道1例因吞嚥诱发的阵发性房性心动过速。患者男性,52岁,吞嚥时伴头晕、面色苍白及下胸部不适已3个月,进干食时明显。吞钡检查发现小的可复性裂孔疝及食道蠕动消失。吞嚥时,出现不规则房性心动过速,频率为160～220/min。该患者心动过速还可由下述方法引起:在距门齿25～45cm 的食道任何部位放置一气球,注入4～20ml 空气使其膨胀,随着注入空气量的增多,心动过速即可发生,并持续存在至气球放气。如将患者倾斜60°可减少对气球膨胀的反应,奎尼丁和心得安可有同样效果,右星状神经节阻滞,阿托品及颈动脉窦按摩均无效。心内研究结果表明,传导间期、窦房结功能和不应期均
This article reports a case of swallowing induced paroxysmal atrial tachycardia. Male, 52 years old, swallowing with dizziness, pale and chest discomfort have been 3 months into the dry food significantly. Barium swallow found a small refolding hiatal hernia and esophageal peristalsis disappeared. Swallowing, there is irregular atrial tachycardia, the frequency of 160 ~ 220 / min. The patient tachycardia can also be caused by the following method: placing a balloon in any part of the esophagus 25 ~ 45cm away from the incisors, infuse 4 ~ 20ml of air to inflate, as the amount of injected air, tachycardia can occur, And persist to the balloon deflation. Such as the patient tilted 60 ° can reduce the balloon dilation response, Quinidine and enzepam have the same effect, right stellate ganglion block, atropine and carotid sinus massage are invalid. The results of intracardiac studies show that the conduction period, sinus node function and refractory period are
