A 69-year-old patient came to the Emergency Department with dyspnea on exertion. ECG showed QRS alternans and echocardiography showed pericardial effusion. The diagnosis 'pericarditis carcinomatosis' was made after pericardial fenestration. QRS alternans is caused by the swinging motion of the heart, due to the excess of pericardial fluid.
一名69岁患者因劳力性呼吸困难来到急诊科。心电图显示QRS波交替，超声心动图显示心包积液。心包开窗术后诊断为“癌性心包炎”。QRS波交替是由于心包积液过多导致心脏摆动运动引起的。
