Two female patients undergoing left atrial radiofrequency catheter ablation developed Tako-tsubo cardiomyopathy. This reversible form of left ventricular dysfunction is known to occur under conditions associated with marked sympathetic nervous activation. Radiofrequency catheter ablation in the left atrium can damage autonomic ganglionated plexi, leading to vagal withdrawal, thus resulting in enhanced sympathetic tone. Tako-tsubo cardiomyopathy has not been previously described following radiofrequency catheter ablation.
两名接受左心房射频导管消融术的女性患者发生了应激性心肌病。这种左心室功能障碍的可逆形式已知在与明显交感神经激活相关的情况下发生。左心房射频导管消融可损伤自主神经节丛，导致迷走神经张力减退，从而导致交感神经张力增强。此前尚未有射频导管消融术后发生应激性心肌病的报道。
