我们报告一个短暂的tako-tsubo心肌病的特点是一个不寻常的触发器在一个妇女受害者的近溺水综合征。24小时后，尽管没有胸痛，心电图变化和典型的心尖气球样变超声心动图模式伴血清肌钙蛋白水平轻度升高，但仍怀疑为Tako-tsubo心肌病。左心室造影证实心尖部气球样变，冠状动脉造影显示冠状动脉正常。心电图改变和心尖收缩异常在1个月内逆转。总之，我们推测，低氧血症相关的溺水综合征可能会引起短暂的心肌功能障碍介导的交感神经激活。
We report a case of transient tako-tsubo cardiomyopathy characterized by an unusual trigger in a woman victim of near-drowning syndrome. After 24h, electrocardiogram changes and a typical echocardiographic pattern of apical ballooning with a mild increase of serum troponin level induced the suspicion of tako-tsubo cardiomyopathy despite the absence of chest pain. Left ventriculography confirmed the apical ballooning, and coronary angiography revealed normal coronary arteries. Electrocardiogram changes and apical contraction abnormalities were reversed within 1 month. In conclusion, we hypothesize that hypoxemia related to near-drowning syndrome could have induced transient myocardial dysfunction mediated by a sympathetic nerve activation.
