Abstract

A 58-year-old man presented with worsening dyspnea. Electrocardiogram showed variation in T-wave amplitude occurring every other beat. Transthoracic echocardiography revealed a severe aortic stenosis with beat-to-beat variation in stroke volume, suggestive of pulsus alternans. Recognition of pulsus alternans is important because it is considered a marker of poor prognosis.

摘要

一名58岁男性因呼吸困难加重前来就诊。心电图显示每隔一次心跳T波振幅就有变化。经胸超声心动图显示严重主动脉瓣狭窄，每搏量逐搏变化，提示交替脉。认识到交替脉很重要，因为它被认为是预后不良的一个指标。
