Despite the development of ventricular assist devices, cardiac transplantation remains an important procedure for patients with advanced heart failure. The number of transplants done annually has remained stable because of lack of of donors. Left ventricular systolic dysfunction remains one of the most important reasons for seeking a donor heart. Myocardial stunning is an important cause of reversible systolic dysfunction. Electrical injury is a recognized cause of myocardial stunning with variable duration ranging from days to weeks. Repeating the transthoracic echocardiogram to look for reversibility of left ventricular dysfunction can be a cost-effective method to improve the selection of heart donors. This can significantly help to decrease critical organ shortage. We present a case of myocardial stunning after electrocution which was completely reversible within a few hours, thus meeting cardiac transplant donor criteria.
尽管心室辅助装置不断发展，但心脏移植对于晚期心力衰竭患者而言仍是一项重要的手术。由于供体短缺，每年进行的移植手术数量一直保持稳定。左心室收缩功能障碍仍然是寻求心脏供体的最重要原因之一。心肌顿抑是可逆性收缩功能障碍的一个重要原因。电击伤是心肌顿抑的一个公认病因，其持续时间长短不一，从数天到数周不等。重复进行经胸超声心动图检查以寻找左心室功能障碍的可逆性，可能是一种具有成本效益的方法，有助于改进心脏供体的选择。这可显著有助于减少重要器官短缺的情况。我们报告一例电击伤后心肌顿抑的病例，该病例在数小时内完全可逆，从而符合心脏移植供体标准。
