A 60-year-old woman presented with acute pulmonary edema followed by cardiopulmonary arrest due to idiopathic ventricular fibrillation. Owing to immediate cardioversion, her electrocardiogram showed sinus rhythm and echocardiography did not show any wall motion abnormalities. The next day, echocardiographic re-examination was characterized by akinesis of both apical and mid segments of the left ventricle. One hour later, subsequently performed coronary angiography revealed non-occlusive coronary artery disease, but left ventriculography demonstrated only akinesis of mid-ventricular segment with hypercontractile other segments. Further echocardiographic investigation on the following day showed total resolution of left ventricular wall motion abnormalities. The diagnosis of mid-ventricular ballooning syndrome was made according to the findings of left ventriculography. In this case, the time course changes of both patient's pathophysiological condition and echocardiographic wall motion from the onset to recovery are rapid and uncommon.
一位 60 岁女性因特发性室颤导致急性肺水肿继而心跳呼吸骤停。由于立即进行了心脏复律，她的心电图显示窦性心律，超声心动图未显示任何壁运动异常。第二天，超声心动图复查显示左心室心尖段和中段均出现无运动。1 小时后，随后进行的冠状动脉造影显示非阻塞性冠状动脉疾病，但左心室造影仅显示中段心室运动障碍，其他节段收缩亢进。第二天进一步的超声心动图检查显示左心室壁运动异常完全消失。根据左心室造影的结果，诊断为中段心室球囊样综合征。在这种情况下，患者的病理生理状况和超声心动图壁运动从发病到恢复的时间过程变化迅速且不常见。
