A 66-year-old woman with atrial fibrillation and hypertension developed tako-tsubo cardiomyopathy following acutely uneventful radiofrequency catheter ablation of the atrioventricular (AV) node. We speculate that the increase in sympathetic activity that accompanies AV node ablation contributed to the pathophysiological process, which involves increased catecholamines and/or apical adrenoreceptor density and responsiveness.
一名66岁患有心房颤动和高血压的女性，在房室结进行急性平稳的射频导管消融术后发生了应激性心肌病。我们推测，房室结消融伴随的交感神经活动增加促成了这一病理生理过程，该过程涉及儿茶酚胺增加和/或心尖部肾上腺素能受体密度及反应性增加。
